Molecular phylogeny and evolution of world Tachinidae (Diptera)

Revision of the Neotropical Obscure Genus Ebenia Macquart 1846 (Diptera, Tachinidae, Dufouriini)

The Neotropical genus Ebenia Macquart, 1846, is a member of the tribe Dufouriini (Dexiinae), and before the current work, comprised four species, viz. E. claripennis Macquart 1846, E. fumata (Wulp, 1891), E. neofumata Santis & Nihei, 2022 and E. trichopoda (Wulp, 1891). The present taxonomic revision results in a new generic synonymy: Comyops Wulp, 1891 syn. nov. of Ebenia. The following two new combinations result from this act: E. nigripennis (Wulp, 1891) comb. nov. and E. striaticollis (Wulp, 1891) comb. nov. both originally described in Comyops. In addition, the species originally described as Homodexia spinosa Bigot, 1889 is moved from its current placement in Thelairodes Wulp, 1891 to Ebenia as Ebenia spinosa (Bigot, 1889) comb. nov. A new specific synonymy is proposed for this last species: Morinia trichopoda Wulp, 1891, previously treated as a valid species of Ebenia, becomes a junior synonym of E. spinosa. All valid species are redescribed and photographed with the first description and illustration of the male terminalia for E. claripennis, E. neofumata and E. nigripennis and female terminalia for E. spinosa. Additionally, lectotype fixations are made for E. nigripennis and M. trichopoda. Finally, an updated diagnosis for the genus Ebenia and a key to the six known species are provided.

Phylogenomics resolves long-standing questions about the affinities of an endangered Corsican endemic fly

Recent studies on oestroidean Diptera (Brachycera) are providing a comprehensive and nuanced understanding of the evolutionary history of this remarkably diverse clade of holometabolous insects. The Oestroidea, which includes formidable pests such as various blowflies, botflies, and flesh flies that infest livestock, pets and humans, are mostly composed of beneficial species that act as scavengers or parasitoids on various pest insects. In our research, we used genomic methods to elucidate the phylogenetic position of Nesodexia corsicana Villeneuve, 1911 (Diptera: Calliphoridae), a mysterious oestroid species endemic to Corsica and characterized by distinctive morphological features that have puzzled taxonomists for years. Contrary to initial hypotheses, our results place Nesodexia Villeneuve, 1911 within the Calliphoridae subfamily Rhinophorinae, a small lineage of terrestrial isopod parasitoids. Through detailed morphological analysis of adults of both sexes and eggs, we uncovered significant insights consistent with our phylogenomic reconstruction. The unique morphological features of the species, coupled with its restricted and fragmented habitat, highlight its potential conservation importance. We delineated the area of occupancy for N. corsicana and assessed its "threatened" category using specific IUCN Red List criteria. In addition, we mapped the available habitat within its range and determined potential key biodiversity areas (KBA) triggered by N. corsicana. New potential KBAs are only partially covered by the Corsican Regional Park. Finally, we mapped the distribution of habitats on the island to assess the potential distribution of the species beyond its currently known geographic range.

The complete mitochondrial genome of Vibrissina turrita (Meigen, 1824) (Diptera, Tachinidae)

In this study, the mitogenome of Vibrissina turrita (Meigen, 1824) (Diptera, Tachinidae) was sequenced based on the next-generation sequencing approach and analyzed here for the first time. The 17,387 bp genome has a high A + T content and consists of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one noncoding control region. The phylogenetic analysis results support that Exoristinae is monophyletic and V. turrita belongs to the subfamily. This study reveals the systematic classification status of V. turrita and will enrich the genetic data on Tachinidae.

A parasitoid regulates 20E synthesis and antibacterial activity of the host for development by inducing host nitric oxide production

Parasitoids are important components of the natural enemy guild in the biological control of insect pests. They depend on host resources to complete the development of a specific stage or whole life cycle and thus have evolved towards optimal host exploitation strategies. In the present study, we report a specific survival strategy of a fly parasitoid Exorista sorbillans (Diptera: Tachinidae), which is a potential biological control agent for agricultural pests and a pest in sericulture. We found that the expression levels of nitric oxide synthase (NOS) and nitric oxide (NO) production in host Bombyx mori (Lepidoptera: Bombycidae) were increased after E. sorbillans infection. Reducing NOS expression and NO production with an NOS inhibitor (NG-nitro-L-arginine methyl ester hydrochloride) in infected B. mori significantly impeded the growth of E. sorbillans larvae. Moreover, the biosynthesis of 20-hydroxyecdysone (20E) in infected hosts was elevated with increasing NO production, and inhibiting NOS expression lowered 20E biosynthesis. More importantly, induced NO synthesis was required to eliminate intracellular bacterial pathogens that presumably competed for shared host resources. Inhibiting NOS expression down-regulated the transcription of antimicrobial peptide genes and increased the number of bacteria in parasitized hosts. Collectively, this study revealed a new perspective on the role of NO in host-parasitoid interactions and a novel mechanism for parasitoid regulation of host physiology to support its development.

Three new species and two newly recorded species of Tachininae from Tibet, China (Arthropoda, Insecta, Diptera, Tachinidae)

During our studying of the fauna of Tibet, China, many specimens of the subfamily Tachininae (Diptera, Tachinidae) were collected and examined. Three species are described here as new to science, Leskialatisurstylasp. nov., Trichoformosomyiacuonaensissp. nov., and Tachinajilongensissp. nov., and two species, Nemoraeajavana (Brauer & Bergenstamm, 1894) and N.echinata Mesnil, 1953, are newly recorded from Tibet. In addition to their descriptions, illustrations, and diagnoses, three identification keys are provided. The specimens in this study are kept in the Insect Collection of Shenyang Normal University, China (SYNU).

Unusual rearrangements of mitogenomes in Diptera revealed by comparative analysis of 135 tachinid species (Insecta, Diptera, Tachinidae)

The Tachinidae is one of the most speciose families in Diptera, and the exclusively parasitoid species play an important role in regulating populations of many herbivorous insects in ecosystems, including many agricultural pests. To better comprehend the characteristics and evolution of the mitochondrial genome for the Tachinidae, we are adding a massive amount of new molecular data by assembling the mitogenomes for 71 genera and 135 species from all four tachinid subfamilies through next-generation sequencing, and we are presenting the most comprehensive mitogenomic phylogenetic analysis of this family so far. Extensive rearrangements observed in the mitogenome of Admontia podomyia (Exoristinae) are unique for the entire suborder Cyclorrhapha. The rearrangement pattern suggests that the process involved a tandem duplication of the complete mitogenome, followed by both random and nonrandom loss of one copy of each gene. Additionally, five minor mitogenome rearrangements are discovered and described in three subfamilies. We present the largest species-level phylogenetic hypothesis for Tachinidae to date, based on mitogenomes of 152 species of Tachinidae, representing all four subfamilies and with five non-tachinid outgroups. Our analyses support the monophyly of the Tachinidae and most tribes and genera were recovered with good support, but the higher-level phylogenetic relationships within Tachinidae were poorly resolved, indicating that mitogenome data alone are not enough to unambiguously resolve the deeper phylogenetic relationships within Tachinidae.

Elevational homogenization of mountain parasitoids across six decades

Elevational gradients are characterized by strong environmental changes within small geographical distances, providing important insights on the response of biological communities to climate change. Mountain biodiversity is particularly sensitive to climate change, given the limited capacity to colonize new areas and the competition from upshifting lowland species. Knowledge on the impact of climate change on mountain insect communities is patchy, but elevation is known to influence parasitic interactions which control insect communities and functions within ecosystems. We analyzed a European dataset of bristle flies, a parasitoid group which regulates insect herbivory in both managed and natural ecosystems. Our dataset spans six decades and multiple elevational bands, and we found marked elevational homogenization in the host specialization of bristle fly species through time. The proportion of specialized parasitoids has increased by ca. 70% at low elevations, from 17 to 29%, and has decreased by ca. 20% at high elevations, from 48 to 37%. As a result, the strong elevational gradient in bristle fly specialization observed in the 1960s has become much flatter over time. As climate warming is predicted to accelerate, the disappearance of specialized parasitoids from high elevations might become even faster. This parasitoid homogenization can reshape the ecological function of mountain insect communities, increasing the risk of herbivory outbreak at high elevations. Our results add to the mounting evidence that symbiotic species might be especially at risk from climate change: Monitoring the effects of these changes is urgently needed to define effective conservation strategies for mountain biodiversity.

Abundance, diversity and richness of natural enemies of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), in Zambia

The fall armyworm (FAW), Spodoptera frugiperda, an invasive pest originating from the Americas is a serious pest threatening cereal production and food security in Zambia. We studied the prevalence and abundance of natural enemies of FAW in three Agroecological regions (AERs I, II, and III) to identify those that could potentially serve as bio-control agents. Sampling of FAW parasitoids and predators was done along trunk roads at intervals of 10 km. Molecular sequence analysis and morphological characterization were used to identify natural enemies. Over 11 species of FAW natural enemies, including egg, egg-larval, and larval parasitoids, and predators, were identified in Zambia. The mean number of natural enemies and species richness was higher in AER I and IIa. Consequently, egg parasitism was highest in those two regions, at 24.5% and 12.2%, respectively. Larvae parasitism was highest in AER I (4.8%) and AER III (1.9), although no significant differences were observed. The most abundant and widely distributed parasitoid was Drino sp. (Diptera: Tachinidae), while Rhynocoris segmentarius (Germar) (Hemiptera: Reduviidae) and Belanogaster sp. (Hymenoptera: Vespidae) were the most prevalent predators. Our study reveals the presence of two natural enemies belonging to the genus Tiphia and Micromeriella, uncommon to FAW. Significant differences in the number of parasitoids were observed in polycropping, with the highest recovery of 12 ± 10% from maize + cowpeas + pumpkin and watermelon mixed cropping. The higher the rainfall, the lower the number of natural enemies recorded. Variations in rainfall patterns which affect FAW availability, cropping systems and the three AERs may explain natural enemies' species diversity in Zambia. The information provided in this study can aid the development of a national biological control programme for sustainable management of fall armyworm.

Launching insectphylo.org; a new hub facilitating construction and use of synthesis molecular phylogenies of insects

The Holy Grail of an Insect Tree of Life can only be 'discovered' through extensive collaboration among taxon specialists, phylogeneticists and centralized frameworks such as Open Tree of Life, but insufficient effort from stakeholders has so far hampered this promising approach. The resultant unavailability of synthesis phylogenies is an unfortunate situation given the numerous practical usages of phylogenies in the near term and against the backdrop of the ongoing biodiversity crisis. To resolve this issue, we establish a new online hub that centralizes the collation of relevant phylogenetic data and provides the resultant synthesis molecular phylogenies. This is achieved through key developments in a proposed pipeline for the construction of a species-level insect phylogeny. The functionality of the framework is demonstrated through the construction of a highly supported, species-comprehensive phylogeny of Diptera, built from integrated omics data, COI DNA barcodes, and a compiled database of over 100 standardized, published Diptera phylogenies. Machine-readable forms of the phylogeny (and subsets thereof) are publicly available at insectphylo.org, a new public repository for species-comprehensive phylogenies for biological research.

First report of Aphrialatifrons (Diptera, Tachinidae, Leskiini) in the Canary Islands

Background

The Canary Islands are an archipelago of volcanic origin, located off north-west Africa comprising eight islands. Fuerteventura and Lanzarote are the oldest (20 and 15 millon years old, respectively) and the easternmost islands. The order Diptera is one of the most relevant taxa in the Canary Islands as they constitute the second highest species richness. Within this order, the family Tachinidae is especially interesting as all species are endoparasitoids of arthropods and most species play a key role as pollinators. In the Canary Islands, the family comprises 52 species, with Fuerteventura and Lanzarote harbouring up to 20 species each.

New information

Aphrialatifrons, a Palaearctic tachinid fly, is reported for the first time from the Canary Islands, where it was found on Fuerteventura and Lanzarote. Morphological examination was carried out and the first known barcode of the species is presented. Its potential distribution and source of origin are discussed.

Phylogenetic relationships of the woodlouse flies (Diptera: Rhinophorinae) and the cluster flies (Diptera: Polleniidae)

Phylogenetic relationships within the oestroid subclades Rhinophorinae (Calliphoridae) and Polleniidae were reconstructed for the first time, applying a Sanger sequencing approach using the two protein-coding nuclear markers CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase; 1794 bp) and MCS (molybdenum cofactor sulfurase; 2078 bp). Three genera of Polleniidae and nineteen genera of Rhinophorinae were analyzed together with a selection of taxa representing the major lineages of Oestroidea (non-rhinophorine Calliphoridae, Oestridae, Sarcophagidae, Tachinidae). The selected markers provide good resolution and moderate to strong support of the distal branches, but weak support for several deeper nodes. Polleniidae (cluster flies) emerge as monophyletic and their sister-group relationship to Tachinidae is confirmed. Morinia Robineau-Desvoidy as currently circumscribed emerges as paraphyletic with regard to Melanodexia Williston, and Pollenia Robineau-Desvoidy is the sister taxon of the Morinia-Melanodexia clade. We propose a classification with two subfamilies, Moriniinae Townsend (including Morinia, Melanodexia, and Alvamaja Rognes), and Polleniinae Brauer & Bergenstamm (including Pollenia, Dexopollenia Townsend, and Xanthotryxus Aldrich). Anthracomyza Malloch and Nesodexia Villeneuve are considered as Oestroidea incertae sedis pending further study. Rhinophorinae (woodlouse flies) emerge as monophyletic and sister to a clade composed of (Ameniinae + (Ameniinae + Phumosiinae)), and a tribal classification is proposed with the subfamily divided into Rhinophorini Robineau-Desvoidy, 1863 and Phytonini Robineau-Desvoidy, 1863 (the Stevenia-group and the Phyto-group of authors, respectively). Oxytachina Brauer & Bergenstamm, 1891, stat. rev. is resurrected to contain nine Afrotropical rhinophorine species currently assigned to genus Rhinomorinia Brauer & Bergenstamm, 1891: Oxytachina approximata (Crosskey, 1977) comb. nov., O. atra (Bischof, 1904) comb. nov., O. bisetosa (Crosskey, 1977) comb. nov., O. capensis (Brauer & Bergenstamm, 1893) comb. nov., O. scutellata (Crosskey, 1977) comb. nov., O. setitibia (Crosskey, 1977) comb. nov., O. verticalis (Crosskey, 1977) comb. nov., O. vittata Brauer & Bergenstamm, 1891, and O. xanthocephala (Bezzi, 1908) comb. nov.

Cloak Scavenges the Reactive Oxygen Species around the Larvae of Drino inconspicuoides (Diptera: Tachinidae)

Drino inconspicuoides (Diptera: Tachinidae) is an endoparasitoid that develops inside the lepidopteran host. When the larva of D. inconspicuoides penetrates into the host, Mythimna separata (Lepidoptera: Noctuidae), the larva creates a cap-like structure, called the funnel, by using host hemocytes, forming a respiratory attachment to permit efficient respiration. A newly described cloudy and cottony structure, called the "cloak", is formed outside the funnel within 24 h of parasitism. The cloak contains the host fat body and hemocytes. In this study, we aimed to clarify the function of the cloak, which has to date remained unknown. We hypothesized that the funnel generates reactive oxygen species (ROS) through melanization, and that the cloak detoxifies them. We confirmed that the black pigments of the funnel were caused by melanization, which inevitably generates ROS that are potentially harmful to the D. inconspicuoides larva inside the funnel. The cloak showed high activities of antioxidant enzymes, including superoxide dismutase, glutathione peroxidase, and catalase. These results suggest that the cloak scavenged the ROS from the melanized funnel through the diversion of antioxidant enzymes in the fat body, thereby protecting the D. inconspicuoides larva from oxidative damage.

Evaluation of suitable reference genes for expression analysis using quantitative real-time polymerase chain reaction in the parasitoid Exorista sorbillans (Diptera: Tachinidae)

The parasitoid Exorista sorbillans (Diptera: Tachinidae) is a larval endoparasitoid of the silkworm Bombyx mori, causing severe damage to silkworm cocoon industry. It is also an important natural enemy resource of insect pests in agriculture and forestry. Despite their roles in biocontrol and pest status on sericulture, there has been limited research on the functional studies of dipteran parasitoids. Quantitative real-time polymerase chain reaction (qRT-PCR) is the most commonly used to address gene functions. Using qRT-PCR, stably expressed reference genes under different experimental conditions are required to normalize the expression of target genes. However, no information regarding suitable qRT-PCR reference genes in dipteran parasitoids has been reported. In this study, we evaluate the expression stability of nine commonly used reference genes in insects including eukaryotic translation elongation factor 1δ (eEF1δ), elongation factor 2, 18S ribosomal RNA (18S rRNA), tubulin 3, actin87, ribosomal protein 49 (RP49), ribosomal protein S15, glyceraldehyde-3-phosphate dehydrogenase, and TATA-box binding protein (TBP) in E. sorbillans under different treatments, including tissues, developmental stages, genders, feeding density and pesticide stress, using ∆C_t , BestKeeper, geNorm, Normfinder and RefFinder, respectively. The results showed that the genes RP49, eEF1δ and 18S rRNA were recommended as the most suitable reference genes in E. sorbillans across all experimental conditions. This finding provides the necessary foundation for future functional studies in E. sorbillans and its effective use in both sericulture and pest control.

Exorista sorbillans (Diptera: Tachinidae) parasitism shortens host larvae growth duration by regulating ecdysone and juvenile hormone titers in Bombyx mori (Lepidoptera: Bombycidae)

The tachinid fly, Exorista sorbillans, is a notorious ovolarviparous endoparasitoid of the silkworm, Bombyx mori, causing severe damage to silkworm cocoon industry. Silkworm larvae show typically precocious wandering behavior after being parasitized by E. sorbillans; however, the underlying molecular mechanism remains unexplored. Herein, we investigated the changes in the levels of 20-hydroxyecdysone (20E) and juvenile hormone (JH) titer, and they both increased in the hemolymph of parasitized silkworms. Furthermore, we verified the expression patterns of related genes, which showed an upregulation of 20E signaling and biosynthesis genes but a significant downregulation of ecdysone oxidase (EO), a 20E inactivation enzyme, in parasitized silkworms. In addition, related genes of the JH signaling were activated in parasitized silkworms, while related genes of the JH degradation pathway were suppressed, resulting in an increase in JH titer. Notably, the precocious wandering behavior of parasitized silkworms was partly recoverable by silencing the transcriptions of BmCYP302A1 or BmCYP307A1 genes. Our findings suggest that the developmental duration of silkworm post parasitism could be shortened by regulation of 20E and JH titers, which may help silkworm to resist the E. sorbillans infestation. These findings provide a basis for deeper insight into the interplay between silkworms and E. sorbillans and may serve as a reference for the development of a novel approach to control silkworm myiasis.

Citizen Science Meet South American Tachinids: New Records of Feather-Legged Fly Trichopoda (Galactomyia) pictipennis Bigot (Diptera: Tachinidae) from Chile

The species of Gymnosomatini (Diptera: Tachinidae) are specialized to attack stink bugs (Hemiptera: Pentatomidae). Some of these flies, such as those in the genus Trichopoda Berthold, are conspicuous and represent target species to study with citizen science. Here we report for the first time the distribution range of T. (Galactomyia) pictipennis Bigot, a newly introduced biological control species of tachinid for use against stink bugs in Chile using data obtained through the citizen science method. Additionally, we update the distribution of T. arcuata (Bigot), a native biological control species of tachinid, and assess the grade of overlap between the flies and their main stink bug hosts. We obtained data regarding the occurrence of flies and stink bugs from the citizen science program "Moscas Florícolas de Chile," from Facebook groups, and from iNaturalist. We standardized our data to avoid temporal, spatial, and geographic biases. We report the extent of occurrence (EOO) and area of occupancy (AOO) for each fly and stink bug species. The EOOs for T. pictipennis and T. arcuata are 85,474 km² and 20,647 km² through central Chile ecosystems, respectively. The EOO of T. arcuata is overlapped by 53% with the introduced species. Trichopoda pictipennis has a high percentage of overlap with the EOO of Nezara viridula Linnaeus (61%), whereas T. arcuata has low percentages of overlap with different native Acledra species and with N. viridula. We discuss the potential of citizen science to detect (1) areas with higher diversity or gaps of occurrences, (2) new biological control agents, (3) prey records, (4) negative impacts on non-target species, (5) changes in composition at long-term, and (6) areas to promote conservation biological control in agricultural landscapes.

The complete mitochondrial genome of Peleteria iavana (Diptera, Tachinidae) in Guizhou, China, and its phylogenetic placement

The mitochondrial genome of the tachinid fly Peleteria iavana (Wiedemann, 1819), which belongs to the family Tachinidae, was obtained for the first time using high-throughput sequencing techniques. The complete mitochondrial genome is 15,697 bp in size and consists of 13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNAs and a non-coding control region. The nucleotide composition biases A and T, the overall A + T percentage is up to 78.9% of the entire mitogenome. A phylogenetic analysis of 30 species within the family Tachinidae suggested that P. iavana is most closely related to (Janthinomyia sp.+Lydina aenea). The P. iavana mitochondrial genome will be a fundamental resource for understanding the molecular phylogenetic relationships of the species-rich subfamily Tachininae of Tachinidae.

Heat tolerance variation reveals vulnerability of tropical herbivore-parasitoid interactions to climate change

Assessing the heat tolerance (CTmax) of organisms is central to understand the impact of climate change on biodiversity. While both environment and evolutionary history affect CTmax, it remains unclear how these factors and their interplay influence ecological interactions, communities and ecosystems under climate change. We collected and reared caterpillars and parasitoids from canopy and ground layers in different seasons in a tropical rainforest. We tested the CTmax and Thermal Safety Margins (TSM) of these food webs with implications for how species interactions could shift under climate change. We identified strong influence of phylogeny in herbivore-parasitoid community heat tolerance. The TSM of all insects were narrower in the canopy and parasitoids had lower heat tolerance compared to their hosts. Our CTmax-based simulation showed higher herbivore-parasitoid food web instability under climate change than previously assumed, highlighting the vulnerability of parasitoids and related herbivore control in tropical rainforests, particularly in the forest canopy.

Four New Species of Macquartia (Diptera: Oestroidea) from China and Phylogenetic Implications of Tachinidae

Macquartia Robineau-Desvoidy (Diptera: Tachinidae, Tachininae) represents one of the most ancient evolutionary lineages of tachinids, parasitizing Chrysomelidae larvae. We found four new Macquartia species collected by malaise traps, namely M. brunneisquama sp. nov., M. chinensis sp. nov., M. flavifemorata sp. nov., and M. flavipedicel sp. nov. These new species are described and illustrated, and their comparison with congeners as well as an identification key to the 12 species of Macquartia from China known to date are included. To determine the significance of the mitogenome architecture and evolution across different tachinid lineages of this primitive taxonomic group, four complete mitochondrial genomes were sequenced, annotated, and analyzed. The gene arrangements are consistent with the ancestral insect mitogenomes. The full-length sequences and protein-coding genes (PCGs) of the mitogenomes of the four species are all AT-biased. Analyses of Ka/Ks and overall p-genetic distance demonstrated that nad5 showed the highest evolutionary rate and nad1/nad4L were the most conserved genes among the four species. Phylogenetic reconstruction based on 13 PCGs strongly supported the monophyly of Macquartia, and the relationships of the four species are (M. flavifemorata + (M. flavipedicel + (M. brunneisquama + M. chinensis))). This study will help enhance our understanding of the taxonomic status and phylogenetic relationships in Tachinidae.

Comparative morphology of antennal ultrastructure in Tachinidae parasitoid flies (Diptera): The phylogenetic importance of antennal sensilla

Tachinidae are one of the most diverse clades of Diptera. All tachinids are parasitoids of insects and other arthropods, and thus are considered an important source of biological pest control. Antennae are the most important olfactory organs of Tachinidae playing key roles in their lives, especially in locating hosts, and details of antennal ultrastructure could provide useful features for phylogenetic studies and understanding their adaptive evolution. Despite the ecological and evolutionary importance of antennae, the current knowledge of antennal ultrastructure is scarce for Tachinidae. Our study examined antennal sensilla of thirteen species belonging to thirteen genera within eleven tribes of all the four subfamilies (Phasiinae, Dexiinae, Tachininae, and Exoristinae): Beskia aelops Walker, Trichodura sp., Voria ruralis (Fallén), Zelia sp., Cylindromyia carinata Townsend, Phasia xenos Townsend, Neomintho sp., Genea australis (Townsend), Copecrypta sp., Hystricia sp., Belvosia sp., Leschenaultia sp., and Winthemia pinguis (Fabricius). Types, length and distribution of antennal sensilla were investigated via scanning electron microscopy (SEM). Our comparative analysis summarized 29 variable characters and we evaluated their phylogenetic signal for subfamilial, tribal and generic/specific levels, showing that antennal ultrastructure could be a reliable source of characters for phylogenetic analysis. Our findings demonstrate the remarkable diversity of the antennal ultrastructure of Tachinidae.

Parasitism by the Tachinid Parasitoid Exorista japonica Leads to Suppression of Basal Metabolism and Activation of Immune Response in the Host Bombyx mori

The dipteran tachinid parasitoids are important biocontrol agents, and they must survive the harsh environment and rely on the resources of the host insect to complete their larval stage. We have previously demonstrated that the parasitism by the tachinid parasitoid Exoristajaponica, a pest of the silkworm, causes pupation defects in Bombyx mori. However, the underlying mechanism is not fully understood. Here, we performed transcriptome analysis of the fat body of B. mori parasitized by E. japonica. We identified 1361 differentially expressed genes, with 394 genes up-regulated and 967 genes down-regulated. The up-regulated genes were mainly associated with immune response, endocrine system and signal transduction, whereas the genes related to basal metabolism, including energy metabolism, transport and catabolism, lipid metabolism, amino acid metabolism and carbohydrate metabolism were down-regulated, indicating that the host appeared to be in poor nutritional status but active in immune response. Moreover, by time-course gene expression analysis we found that genes related to amino acid synthesis, protein degradation and lipid metabolism in B. mori at later parasitization stages were inhibited. Antimicrobial peptides including Cecropin A, Gloverin and Moricin, and an immulectin, CTL11, were induced. These results indicate that the tachinid parasitoid perturbs the basal metabolism and induces the energetically costly immunity of the host, and thus leading to incomplete larval-pupal ecdysis of the host. This study provided insights into how tachinid parasitoids modify host basal metabolism and immune response for the benefit of developing parasitoid larvae.

A world review of the bristle fly parasitoids of webspinners

Background

Dipteran parasitoids of Embioptera (webspinners) are few and extremely rare but known from all biogeographical regions except Australasia/Oceania. All belong to the fly family Tachinidae, a hyperdiverse and widespread clade of parasitoids attacking a variety of arthropod orders.

Results

The webspinner-parasitizing Diptera are reviewed based mostly on records from the collecting and rearing by Edward S. Ross. A new genus is erected to accommodate a new Afrotropical species, Embiophoneus rossi gen. et sp. nov. The genus Perumyia Arnaud is reviewed and a new species, Perumyia arnaudi sp. nov., is described from Central America while P. embiaphaga Arnaud is redescribed and new host records are given. A new species of Phytomyptera Rondani, P. woodi sp. nov., is described from Myanmar, representing the first report of a member of this genus obtained from webspinners. The genus Rossimyiops Mesnil is reviewed, R. longicornis (Kugler) is redescribed and R. aeratus sp. nov., R. fuscus sp. nov. and R. rutilans sp. nov. are newly described from the Oriental Region, and an updated key to species is given.

Conclusions

Webspinners were probably colonized independently at least four times by tachinids shifting from other hosts, most likely Lepidoptera.

Molecular Analysis of Parasitoid Flies Tachinidae

The parasitoids from Tachinidae family have important role in biological control; nevertheless, the phylogenetic relationships of supra genera groups are poorly studied. Here, we present phylogenetic analyses of the family based on molecular data. 73 species of parasitoid flies belonging to 30 tachinid genera, including the four currently recognized subfamilies (Dexiinae, Exoristinae, Phasiinae, Tachininae) and 20 tribes were analyzed in the molecular study. The Tachinidae are reconstructed as a monophyletic assemblage based on morphological data and with four nonhomoplasious apomorphies (synapomorphies). Monophyly is well supported by a bootstrap value. Our morphological analysis generally supports the subfamily grouping Dexiinae + Phasiinae, while Tachininae + Exoristinae is not supported as one group, and with only the Exoristinae and the Phasiinae reconstructed as monophyletic assemblages. The Dexiinae, which were previously considered a wellestablished monophyletic assemblage (except for few studies), are reconstructed as polyparaphyletic with respect to the Phasiinae. The Tachininae are reconstructed as a paraphyletic grade, while monophyly of Exoristinae was recovered except genus Admontia Brauer Bergenstamm, which arose within subfamily Tachininae. In contrast to molecular analysis, all subfamilies are polyparaphyletic groups in which they interact with each other, with the exception of Phasiinae, which includes most of its taxa in a monophyletic group.

Characterization and Comparative Analysis of Mitochondrial Genomes Among the Calliphoridae (Insecta: Diptera: Oestroidea) and Phylogenetic Implications

The Calliphoridae (blowflies) are significant for forensic science, veterinary management, medical science, and economic issues. However, the phylogenetic relationships within this family are poorly understood and controversial, and the status of the Calliphoridae has been a crucial problem for understanding the evolutionary relationships of the Oestroidea these years. In the present study, seven mitochondrial genomes (mitogenomes), including six calliphorid species and one Polleniidae species, were sequenced and annotated. Then a comparative mitochondrial genomic analysis among the Calliphoridae is presented. Additionally, the phylogenetic relationship of the Calliphoridae within the larger context of the other Oestroidea was reconstructed based on the mitogenomic datasets using maximum likelihood (ML) and Bayesian methods (BI). The results suggest that the gene arrangement, codon usage, and base composition are conserved within the calliphorid species. The phylogenetic analysis based on the mitogenomic dataset recovered the Calliphoridae as monophyletic and inferred the following topology within Oestroidea: (Oestridae (Sarcophagidae (Calliphoridae + (Polleniidae + (Mesembrinellidae + Tachinidae))))). Although the number of exemplar species is limited, further studies are required. Within the Calliphoridae, the Chrysomyinae were recovered as sister taxon to Luciliinae + Calliphorinae. Our analyses indicated that mitogenomic data have the potential for illuminating the phylogenetic relationships in the Oestroidea as well as for the classification of the Calliphoridae.

Effect of Tachinid Parasitoid Exorista japonica on the Larval Development and Pupation of the Host Silkworm Bombyx mori

The Tachinidae are natural enemies of many lepidopteran and coleopteran pests of crops, forests, and fruits. However, host-tachinid parasitoid interactions have been largely unexplored. In this study, we investigated the effects of tachinids on host biological traits, using Exorista japonica, a generalist parasitoid, and the silkworm Bombyx mori, its lepidopteran host, as models. We observed that E. japonica parasitoidism did not affect silkworm larval body weight gain and cocooning rate, whereas they caused shortened duration of molting from the final instar to the pupal stage, abnormal molting from larval to pupal stages, and a subsequent decrease in host emergence rate. Moreover, a decrease in juvenile hormone (JH) titer and an increase in 20-hydroxyecdysone (20E) titer in the hemolymph of parasitized silkworms occurred. The transcription of JH and 20E responsive genes was downregulated in mature parasitized hosts, but upregulated in parasitized prepupae while Fushi tarazu factor 1 (Ftz-f1), a nuclear receptor essential in larval ecdysis, showed dramatically reduced expression in parasitized hosts at both the mature and prepupal stages. Moreover, the transcriptional levels of BmFtz-f1 and its downstream target genes encoding cuticle proteins were downregulated in epidermis of parasitized hosts. Meanwhile, the content of trehalose was decreased in the hemolymph, while chitin content in the epidermis was increased in parasitized silkworm prepupae. These data reveal that the host may fine-tune JH and 20E synthesis to shorten developmental duration to combat established E. japonica infestation, while E. japonica silences BmFtz-f1 transcription to inhibit host pupation. This discovery highlights the novel target mechanism of tachinid parasitoids and provides new clues to host/tachinid parasitoid relationships.

Annotated catalogue of the Tachinidae (Insecta, Diptera) of Chile

The Tachinidae (Diptera) of Chile are catalogued and information is given on distributions, name-bearing types, synonyms, nomenclatural issues, and pertinent literature. The history of tachinid collectors in Chile and authors who have contributed to the systematic knowledge of Chilean tachinids is extensively reviewed. The classification has been updated and 122 genera and 264 species are recognised in Chile. There is a significant amount of endemism with 28 genera and 100 species known only from Chile. There are also 113 species with distributions shared only between Chile and Argentina, particularly in the southern portions of these countries comprising Patagonia. The catalogue is based on examination of the original descriptions of all nominal species and all other references known to us containing relevant taxonomic and distributional information, for a total of approximately 450 references. Many of the name-bearing types and other Chilean specimens housed in collections were examined. Taxa are arranged hierarchically and alphabetically under the categories of subfamily, tribe, genus, subgenus (where recognised), and species. Nomenclatural information is provided for genus-group and species-group names, including lists of synonyms (mostly restricted to Neotropical taxa) and name-bearing type data. Species distributions are recorded by country within the New World and by larger geographical divisions in the Old World. Additional information is given in the form of notes and references under valid names at the level of tribe, genus, and species. Two genera are newly recorded from Chile: Chaetoepalpus Vimmer & Soukup, 1940 (Tachinini) (also newly recorded from Argentina) and Patelloa Townsend, 1916 (Goniini). Four species are newly recorded from Chile or other countries: Lyphaornata Aldrich, 1934 (Chile); Chaetoepalpuscoquilleti Vimmer & Soukup, 1940 (Argentina and Chile); Phytomypteraevanescens (Cortés, 1967) (Argentina); and Xanthobasisunicolor Aldrich, 1934 (Chile).

Phylogenomics reveals accelerated late Cretaceous diversification of bee flies (Diptera: Bombyliidae)

Bombyliidae is a very species-rich and widespread family of parasitoid flies with more than 250 genera classified into 17 extant subfamilies. However, little is known about their evolutionary history or how their present-day diversity was shaped. Transcriptomes of 15 species and anchored hybrid enrichment (AHE) sequence captures of 86 species, representing 94 bee fly species and 14 subfamilies, were used to reconstruct the phylogeny of Bombyliidae. We integrated data from transcriptomes across each of the main lineages in our AHE tree to build a data set with more genes (550 loci versus 216 loci) and higher support levels. Our overall results show strong congruence with the current classification of the family, with 11 out of 14 included subfamilies recovered as monophyletic. Heterotropinae and Mythicomyiinae are successive sister groups to the remainder of the family. We examined the evolution of key morphological characters through our phylogenetic hypotheses and show that neither the "sand chamber subfamilies" nor the "Tomophthalmae" are monophyletic in our phylogenomic analyses. Based on our results, we reinstate two tribes at the subfamily level (Phthiriinae stat. rev. and Ecliminae stat. rev.) and we include the genus Sericosoma Macquart (previously incertae sedis) in the subfamily Oniromyiinae, bringing the total number of bee fly subfamilies to 19. Our dating analyses indicate a Jurassic origin of the family (165-194 Ma), with the sand chamber evolving early in bee fly evolution, in the late Jurassic or mid-Cretaceous (100-165 Ma). We hypothesize that the angiosperm radiation and the hothouse climate established during the late Cretaceous accelerated the diversification of bee flies, by providing an expanded range of resources for the parasitoid larvae and nectarivorous adults.

Revison of Metaplagia Coquillett (Diptera: Tachinidae) with description of five new species from Area de Conservación Guanacaste in northwestern Costa Rica

Background

We revise the genus Metaplagia Coquillett, 1895 and describe five new species from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica. All new species were reared from an ongoing inventory of wild-caught caterpillars spanning a variety of species within the family Sphingidae (Lepidoptera: Sphingidae). Our study provides a concise description of each new species using morphology, life history, molecular data and photographic documentation. In addition to the new species, the authors provide a re-description of the genus and a revised key to the species of Metaplagia.

New information

The following five new species of Metaplagia are described: Metaplagialeahdennisae Fleming & Wood sp. n., Metaplagialindarobinsonae Fleming & Wood sp. n., Metaplagiapaulinesaribasae Fleming & Wood sp. n., Metaplagiarobinsherwoodae Fleming & Wood sp. n. and Metaplagiasvetlanakozikae Fleming & Wood sp. n.

The following is proposed by Fleming & Wood as new combination of Plagiomima Brauer & Bergenstamm, 1891: Plagiomimalatifrons (Reinhard, 1956) comb. n.

Eudexia Brauer Bergenstamm, 1889, a Dexiini genus restricted to the Neotropical Region, is revised with proposal of the following new synonymies: Chaetocalirrhoe Townsend, 1935 = Eudexia, syn. nov. and Cordillerodexia Townsend, 1927 = Eudexia, syn. nov. As a result, the following new combinations are proposed: Eudexia brevicornis (Macquart, 1851), comb. nov., Eudexia colombiana (Townsend, 1929), comb. nov., Eudexia grandis (Townsend, 1935), comb. nov., and Eudexia orientalis (Townsend, 1927), comb. nov. Redescriptions, photographs and a lectotype designation are provided for the type species Eudexia formidabilis (Bigot, 1889). Diagnoses and photographs are provided for Eudexia colombiana, E. grandis, and E. orientalis, and a diagnosis is provided for E. brevicornis. A new species from Brazil, Eudexia lopesi sp. nov., is described. Finally, an updated diagnosis for the genus Eudexia and a key to the seven known species are given.

Extraordinary diversification of the “bristle flies” (Diptera: Tachinidae) and its underlying causes

The family Tachinidae (“bristle flies”) is the most diverse and ecologically important group of insect parasitoids outside the parasitic wasps. It is among the most species rich families of flies (Diptera) and has experienced a recent adaptive radiation across the globe. We make use of a molecular phylogeny of the family to examine its rapid radiation and explore the traits of tachinid lineages that may have contributed to variation in their diversification. We apply a range of diversification analyses to assess the consistency and robustness of effects. We find that the Tachinidae are among the most rapidly diversifying families of animals. Six to eight clades of bristle flies, distributed across the phylogeny, exhibit strong evidence of accelerated diversification. Our results suggest that the use of holometabolous insect larvae, and specifically caterpillars (Lepidoptera), as hosts, is associated with increased diversification rates. However, these effects were inconsistent across analyses. We detected little influence of oviposition strategy (egg type) or host feeding habit, and we recovered evidence that unmeasured “hidden” traits may explain greater variance in diversification. We evaluated the strengths and weaknesses of different Maximum Likelihood and Bayesian approaches for analysing diversification and the potential for extrinsic factors, such as geography, to influence patterns of richness and diversification. In general, we conclude that although certain traits may provide opportunities for diversification, whether this is capitalized on may depend on additional traits and/or historical contingency.

First report of the mitogenome of Hamaxiella brunnescens (Diptera, Tachinidae) from Beijing, China

Hamaxiella brunnescens (Mesnil, 1967) (Diptera, Tachinidae) is a parasitic fly species and of great ecological importance in natural systems as parasitoids of herbivorous insects. The mitogenome of H. brunnescens was sequenced and analyzed here for the first time. The genome is 14,956 bp in length with high A + T content, which consists of 13 protein-coding, 22 tRNA, two rRNA genes, and a partial non-coding control region. The phylogenetic analyses support a monophyletic Tachinidae. The two subfamilies Exoristinae and Phasiinae are fully supported as monophyletic while Tachininae is inferred to be paraphyletic.

The world Polleniidae (Diptera, Oestroidea): key to genera and checklist of species

A key to the world genera and a checklist of the world species for the family Polleniidae, including distributions, are provided. The following taxonomic and nomenclatural changes are proposed: Nitellia hermoniella Lehrer, 2007 = Pollenia mediterranea Grunin, 1966, syn. nov., Pollenia bentalia Lehrer, 2007 = Pollenia semicinerea Villeneuve, 1911, syn. nov., Dasypoda angustifrons Jacentkovský, 1941 = Pollenia tenuiforceps Séguy, 1928, syn. nov.; Anthracomyza Malloch, 1928, resurrected name (monotypic; type species Anthracomyia atratula Malloch) is considered a valid name and tentatively assigned to Polleniidae, giving Anthracomyza atratula (Malloch, 1927) as a resurrected combination; Morinia crassitarsis (Villeneuve, 1936), stat. rev. is considered a valid species, and Micronitellia Enderlein, 1936, stat. nov. is considered an available name.

Tachinid (Diptera, Tachinidae) parasitoids of Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera, Tortricidae) and other moths

The present paper reports data on the biology of eleven species of tachinid flies collected in Italy and Spain on different host plants and emerged from different host larvae. An annotated list of the eleven species emerged from the collected lepidopterans is provided; information about distribution and biology are given as well as the description of their puparia. Two new parasitoid species of the European Grapevine Moth (EGVM) Lobesia botrana were recorded: Clemelis massilia, whose host preferences were unknown so far, and Neoplectops pomonellae. A list of lepidopteran pest species with their associated plants and tachinid parasitoids is then given in order to highlight the relationships among the three components of the biocenosis (plant, herbivore and parasitoid). Eventually, due to the great economic importance of L. botrana in viticulture, a preliminary identification key to the puparia of its tachinid parasitoids is provided.

A new genus and new species in the tribe Uramyini (Diptera: Tachinidae) from Area de Conservación Guanacaste in northwestern Costa Rica

Background

We describe one new genus and its one new species from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica. Our study provides a concise description of this new species using morphology, life history, molecular data and photographic documentation.

The world woodlouse flies (Diptera, Rhinophoridae)

The world Rhinophoridae are catalogued, recognising 33 genera and 177 species. Nomenclatural information is provided for all genus-group and species-group names, including lists of synonyms and name-bearing type data. Species distributions are recorded by country. A key to the world genera is presented. Four new genera are erected to accommodate five new species, which do not fit within any of the current generic concepts in Rhinophoridae, according to the results of a morphology-based phylogenetic analysis: Marshallicona Cerretti & Pape with type species Marshallicona quitu Cerretti & Pape, gen. et sp. nov. (Ecuador); Maurhinophora Cerretti & Pape with type species Maurhinophora indoceanica Cerretti & Pape, gen. et sp. nov. (Mauritius); Neotarsina Cerretti & Pape with type species Neotarsina caraibica Cerretti & Pape, gen. et sp. nov. (Trinidad and Tobago) and Neotarsina andina Cerretti & Pape, sp. nov. (Peru); Kinabalumyia Cerretti & Pape with type species Kinabalumyia pinax Cerretti & Pape, gen. et sp. nov. (Malaysia, Sabah). The genus Aporeomyia Pape & Shima (type species Aporeomyia antennalis Pape & Shima), originally assigned to Tachinidae, is here reassigned to Rhinophoridae based on a reassessment of the homologies of the male terminalia. The following five species-group names, which were previously treated as junior synonyms or nomina dubia, are recognised as valid species names: Acompomintho caucasica (Villeneuve, 1908), stat. rev. [from nomen dubium to valid species]; Acompomintho sinensis (Villeneuve, 1936), stat. rev. [from nomen dubium to valid species]; Stevenia bertei (Rondani, 1865), stat. rev. [from nomen dubium to valid species]; Stevenia sardoa Villeneuve, 1920, stat. rev. [from junior synonym of Rhinophora deceptoria Loew, 1847 to valid species]; Stevenia subalbida (Villeneuve, 1911), stat. rev. [from junior synonym of Rhinophora deceptoria Loew, 1847 to valid species]. Reversal of precedence is invoked for the following case of subjective synonymy to promote stability in nomenclature: Rhinophora lepida (Meigen, 1824), nomen protectum, and Musca parcus Harris, 1780: 144, nomen oblitum. New generic and specific synonymies are proposed for the following two names: Mimodexia Rohdendorf, 1935, junior synonym of Tromodesia Rondani, 1856, syn. nov. and Ptilocheta tacchetti Rondani, 1865, junior synonym of Stevenia obscuripennis (Loew, 1847), syn. nov. The following new combinations are proposed: Acompomintho sinensis (Villeneuve, 1936), comb. nov. [transferred from Tricogena Robineau-Desvoidy, 1830]; Tromodesia guzari (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia intermedia (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia lindneriana (Rohdendorf, 1961), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia magnifica (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia obscurior (Rohdendorf, 1935), comb. nov. [transferred from Mimodexia Rohdendorf, 1935]; Tromodesia pallidissima (Rohdendorf, 1935), comb. nov.

A new synonym for Zelia Robineau-Desvoidy, 1830 (Diptera, Tachinidae), the genus Opsozelia Townsend, 1919, with the description of three new species

The monotypic tachinid genus Opsozelia Townsend, 1919 (Diptera: Tachinidae) is synonymized with ZeliaRobineau-Desvoidy 1830, syn. nov. The single species of Opsozelia, O. discalis Townsend, 1919, is redescribed as Zelia discalis, comb. nov., based on examination of the holotype from Guyana and additional material from Suriname, Brazil and Paraguay. Three new species of Zelia similar to Z. discalis are described from Brazil: Z. magna sp. nov., Z. guimaraesi sp. nov. and Z. formosa sp. nov. These four species are treated informally as the Zelia discalis species group. An identification key to the species of this species group is provided based on male specimens. Descriptions and illustrations are provided for the male terminalia of all species and for the female terminalia of one species, Z. guimaraesi.

The complete mitochondrial genome of Exorista japonica (Townsend, 1909) (Diptera:Tachinidae)

Exorista japonica (Townsend, 1909), a dipteran tachinid fly, is an endoparasitoid of lepidopteran larvae as a potential biological agent. We have determined a 17,663 bp mitogenome of E. japonica which includes 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs, and a single large non-coding region of 2,773 bp. The base composition was AT-biased (81.4%). Phylogenetic trees present monophyly of Tachinidae and Exoristinae, where two Exorista species are clustered in single clade, Exoristini. The E. japonica mitogenome will be a good resource for understanding phylogenetic relationship among species of Tachinidae presenting morphological and ecological complexities.
