Abstract
Alpha taxonomy is fundamental for many biological fields. Delineation of the species boundary, however, can be challenging in a species complex, where different species share a similar morphology and diagnostic characters may not be available. In this context, integrative approaches that incorporate molecular and morphological data sets, and account for speciation history can be helpful to alpha taxonomy. Different approaches to species delimitation based on different assumptions are complementary and by integrating the results from multiple approaches we can generate a more reliable and objective taxonomic decision. In this study, we applied three molecular approaches to species delimitation and inferred the demographic history based on an isolation with migration model to test a morphologically based taxonomic hypothesis for the Cylindera pseudocylindriformis complex. We discuss the association between genetic divergence and microhabitat specialisation, and further corroborate that C. subtilis sp. nov. is a valid new species by integrating the results from model-based species delimitation and the genealogical divergence index. We argue that genetic endemism can occur at a small geographic scale, even in a winged insect like tiger beetles. Our results also indicated that there may still be undocumented species diversity of Taiwanese Cylindera remaining to be discovered.

Chou MH, Yeh WB. Delineation of two new, highly similar species of Taiwanese Cylindera tiger beetles (Coleoptera, Carabidae, Cicindelinae) based on morphological and molecular evidence. Zookeys 2019; 875:31-62.

Abstract
Tiger beetles have been recognized primarily based on morphological characters. However, the variations of elytral maculation and coloration sometimes lead to misjudgment in species classification and the overlooking of the existence of cryptic species. Recently, specimens of two endemic species of Taiwanese Cylindera, C.sauteri and C.pseudocylindriformis, exhibit morphologically recognizable forms, indicating that some undescribed species may exist. To clarify their taxonomic status, morphological characteristics including male genitalia were examined and two mitochondrial genes, COI and 16S rDNA, and one nuclear 28S rDNA were analyzed. Molecular phylogenetic inferences indicated that both forms in both species are reciprocally monophyletic. Moreover, molecular dating showed the forms diverged approximately 1.3 million years ago. Two new species, Cylinderaooasp. nov. and Cylinderaautumnalissp. nov., are thereby described. The main recognizable characteristics separating C.ooasp. nov. from C.sauteri are the lack of a triangular spot at the middle edge of elytron and the elongated but not rounded subapical spot. For C.autumnalissp. nov., the apical lunula near the elytral suture is thickened but not linear and slender, and its elytra are more metallic brownish than those of C.pseudocylindriformis. Although their aedeagi characteristics are not distinctive, the body size of the proposed two new species is different. Field observation revealed that niche utilization would be relevant for differentiating these closely related species.

Characterisation and expression analysis of UBC9 and UBS27 genes in developing gonads of cicindelids (Coleoptera: Cicindelidae). Comp Biochem Physiol B Biochem Mol Biol 2016; 202:75-82.

Abstract
Ubiquitin and small ubiquitin-like modifiers (SUMO) are post-translational modifiers essential in a variety of cellular processes, including gametogenesis. SUMO-conjugating enzyme (UBC9) and the ubiquitin ribosomal fusion protein UBS27 have been characterised in several model species. However, their expression in coleopteran remains unstudied. In this study, UBC9 and UBS27 genes have been characterised in the tiger beetle Cicindela campestris for the first time. Bioinformatic analysis showed that the Cc-UBC9 gene encoded a 159 amino acid protein with a predicted molecular weight of 18.18kDa, and the Cc-UBS27 gene encoded a 156 amino acid protein with a predicted molecular weight of 17.71kDa. Selection analyses carried out in several cicindelid species revealed that both genes were affected by purifying selection. Real time quantitative PCR analysis demonstrated that Cc-UBC9 and Cc-UBS27 were expressed in different tissues. The highest expression on both genes was found in the ovary and testis, and there were differential expression levels between immature and mature stages of testis development. The expression patterns of Cc-UBC9 and Cc-UBS27 suggest that these genes play important roles in gametogenesis in C. campestris. This information is relevant to better understand the reproductive process in cicindelids and the function of ubiquitin and small ubiquitin-related modifier genes in the Coleoptera.

Pleistocene phylogeography and cryptic diversity of a tiger beetle, Calomera littoralis, in North-Eastern Mediterranean and Pontic regions inferred from mitochondrial COI gene sequences. PeerJ 2016; 4:e2128. [PMID: 27547517 PMCID: PMC4958013 DOI: 10.7717/peerj.2128] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2016] [Accepted: 05/23/2016] [Indexed: 11/23/2022] Open
Abstract
Background. Calomera littoralis is a Palearctic species, widely distributed in Europe; inhabiting predominantly its Atlantic, Mediterranean and Black Sea coastlines. Methods. Its phylogeography on the Balkan Peninsula and on the north-western Black Sea coast was inferred using a 697 bp long portion of the mitochondrial COI gene, amplified from 169 individuals collected on 43 localities. Results. The results revealed two genetically divergent groups/lineages, the southern one inhabiting both the Balkan Peninsula and the Pontic Region and the northern one found exclusively in the Pontic Region. Species delimitation based on DNA barcoding gap suggested an interspecific level of divergence between these groups. Multivariate analysis of eight male and female morphometric traits detected no difference between the groups, implying they may represent cryptic species. The Bayesian time-calibrated reconstruction of phylogeny suggested that the lineages diverged ca. 2.3 Ma, in early Pleistocene. Discussion. The presence of the two genetically divergent groups results most likely from contemporary isolation of the Pontic basin from the Mediterranean that broke the continuous strip of coastal habitats inhabited by C. littoralis. Demographic analyses indicated that both lineages have been in demographic and spatial expansion since ca. 0.15 Ma. It coincides with the terminal stage of MIS-6, i.e., Wartanian/Saalian glaciation, and beginning of MIS-5e, i.e., Eemian interglacial, during which, due to eustatic sea level rise, a wide connection between Mediterranean and the Pontic basin was re-established. This, along with re-appearance of coastal habitats could initiate north-east expansion of the southern lineage and its secondary contact with the northern one. The isolation of the Pontic basin from the Mediterranean during the Weichselian glaciation most likely did not have any effect on their phylogeography.

Abstract
A recent molecular phylogenetic study on Glaucus, a genus of neustonic aeolid nudibranchs, revealed undescribed cryptic diversity. Glaucus atlanticus is sister to the traditional species Glaucus marginatus, which is a complex of four genetically distinct cryptic species (Informal clade ‘Marginatus’). The present paper revises the systematics of Glaucus and provides formal descriptions for three new species in the informal clade ‘Marginatus’ substantiated by species delimitation analyses. Molecular and morphological evidence confirms that the type species of Glaucus, Glaucus atlanticus, has a cosmopolitan subtropical distribution and is characterised by having a uniseriate ceratal arrangement, a penial spine and a longitudinal, medial silver stripe on the sole of the foot. Examination of type material indicates that the name G. marginatus should be retained for the most widespread of these species, found in the Indian and Pacific Oceans. This species is characterised by molecular diagnostic characters as well as the presence of a bursa copulatrix. Glaucus marginatus is sister to the undescribed species Glaucus bennettae, sp. nov., which is found in the South Pacific Ocean and lacks a bursa copulatrix. The other two undescribed species, Glaucus thompsoni, sp. nov. and Glaucus mcfarlanei, sp. nov. are only known from the North Pacific Ocean, and are characterised by molecular diagnostic characters as well as possessing and lacking a bursa copulatrix, respectively. Because sister species of Glaucus differ in their reproductive anatomy, we hypothesise that mating behaviour has played a role in cladogenesis in this group.
