Abstract
Phlebotomus perniciosus is the most important vector of Leishmania infantum in the Western part of the Mediterranean basin. Atypical specimens of Ph. perniciosus called (pna) with a parameral sheath simply curved, not bifurcated, have been reported in many locations. In this study, we describe abnormal Ph. perniciosus male specimens. Sand flies were collected in center Tunisia and identified morphologically. Cytochrome b PCR-sequencing was carried out for abnormal Ph. perniciosus male specimens in order to confirm the morphological identification and assess the intraspecific genetic polymorphism. Abnormal Ph. perniciosus specimens were characterized by a multifurcated parameral sheath. A parsimonious haplotype network based on cyt b locus analysis showed that typical and abnormal Ph. perniciosus described in our investigation were grouped together in the same branch. Thus, genetic outcomes confirmed that the new phenotype is only an original morphotype of Ph. perniciosus.

Abstract
The idea of the existence of Phlebotomus (Larroussius) neglectus (Diptera: Psychodidae) Tonnoir, 1921 in Iran and the skepticism about the existence of Phlebotomus major s.str. Annandale, 1910 had been grown recently in the country. This study reports a combined analysis of mitochondrial and ribosomal DNA target regions of P. major s.l.Annandale, 1910, specimens collected from different parts of Iran. Two different morphotypes were found among the collected samples based on the shape of the aedeagus, ventrally located hairs of the coxite, and parameral sheets. One morphotype seemed similar to P. neglectus Tonnoir 1921 or P. major krimensis Perfiliv1966 (called here MI.N.K.); the other one was similar to P. neglectus and to some extent to P. notus Artemiev & Neronov 1984 (here called MII.N.NO). Cytochrome B, elongation factor 1-alpha, and internal transcribed spacer II loci were amplified, sequenced, and characterized. High sequence homology (98-100%) was observed between P. neglectus and these morphotypes, and phylogenetic analysis was also concordant. Phlebotomus neglectus sequences available in GenBank are located as the sister group of sequences here, particularly near to morphotype MII.N.NO. Moreover, ITS2 locus provides the maximum resolution for differentiation of two morphotypes. Based on achieving results, although a strong support for the presence of P. neglectus was provided, but it is too early to say that P. major s.str. does/does not exist in Iran. This question could be resolved by studying more samples and, most importantly, by comparing the topotypes of P. neglectus and P. major s. str. if possible in the future.

Abstract
Phlebotomus (Transphlebotomus) mascittii Grassi, 1908 (Diptera: Psychodidae) has been found in several European countries. In Spain, sporadic records were reported in the early '80s in Catalonia (Northeast Spain), and it was never detected again. Recent entomological surveys carried out between 2004 and 2020 revealed the presence of several specimens of P. mascittii in Spain. The species identification was confirmed by both morphological and molecular analyses. The analyzed specimens belonged to the haplotype (COI_2) defined by one polymorphic site compared to other European specimens. Phlebotomus mascittii was found in low population densities in rural areas associated with livestock farms and in an urban cemetery during the summer season. This study provides the first records of this species in various localities along the Cantabrian cornice (Northern Spain) and represents its westernmost observation in the Palearctic region. The implications of the finding of this uncommon species are discussed at different levels, with emphasis on its suspected role in the transmission of leishmaniosis.

Abstract
Phlebotomine sand flies are the main natural vectors of Leishmania, which cause visceral and tegumentary tropical diseases worldwide. However, their taxonomy and evolutionary history remain poorly studied. Indeed, as for many human disease vectors, their small size is a challenge for morphological and molecular works. Here, we successfully amplified unbiased copies of whole genome to sequence thousands of restriction-site associated DNA (RAD) markers from single specimens of phlebotomines. RAD markers were used to infer a fully resolved phylogeny of the subgenus Paraphlebotomus (11 species + 5 outgroups, 32 specimens). The subgenus was not recovered as monophyletic and we describe a new subgenus Artemievus subg. nov. Depaquit for Phlebotomus alexandri. We also confirm the validity of Ph. riouxi which is reinstated as valid species. Our analyses suggest that Paraphlebotomus sensu nov. originated ca 12.9-8.5 Ma and was possibly largely distributed from peri-Mediterranean to Irano-Turanian regions. Its biogeographical history can be summarized into three phases: i) a first split between Ph. riouxi + Ph. chabaudi and other species that may have resulted from the rise of the Saharan belt ca 8.5 Ma; ii) a Messinian vicariant event (7.3-5.3 Ma) during which the prolonged drought could have resulted in the divergence of main lineages; iii) a recent radiation event (3-2 Ma) that correspond to cycles of wet and dry periods in the Middle East and the East African subregions during the Pleistocene. Interestingly these cycles are also hypothetical drivers of the diversification of rodents, in the burrows of which Paraphlebotomus larvae develop. By meeting the challenge of sequencing pangenomics markers from single, minute phlebotomines, this work opens new avenues for improving our understanding of the epidemiology of leishmaniases and possibly other human diseases transmitted by arthropod vectors.

Abstract
Sand flies are vector of several diseases, mostly cutaneous and visceral leishmaniasis (CL and VL). Also, 29 sand fly species have been identified in previous fauna studies carried out in 40 provinces of Turkey. Totally, 24 sand flies species belonging to Phlebotomus (Ph.) (Diptera: Psychodidae) genus have been proven or reported as possible vector species. This study aimed to develop a new software which could contribute to researchers' decision making about the identification of sand flies with obtained data from entomological surveys conducted before in Turkey. Developed software called TRsandflies included 35 textbox created with parameters obtained from caught sand flies specimens by the above-mentioned surveys. It also contained 130 photos and distribution maps related to 24 sand flies species. In addition, C# language and MYSQL database were used in the program. TRsandflies had three different forms (pages) allowing the user to compare the specimens and known species. In the species identification trials with three repetitions carried out in the program, except for the specimens belonging to the Transphlebotomus Artemiev & Neronov, 1984 subgenus, morphometric data of all previously collected sand fly species specimens were included. The process of running the morphometric measurement results of predetermined specimens in the program provided us with an accurate prediction rate of 86.66% in male specimens and 71.66% in female specimens. We concluded that the web-based software developed could play an important role in reducing the rate of possible errors that might be encountered by conventional identification methods.

Abstract
BACKGROUND Recent climate and environmental changes have resulted in the geographical expansion of Mediterranean Leishmania infantum vectors towards northern latitudes and higher altitudes in different European countries, including Italy, where new foci of canine leishmaniasis have been observed in the northern part of the country. Northern Italy is also an endemic area for mosquito-borne diseases. During entomological surveillance for West Nile virus, mosquitoes and other hematophagous insects were collected, including Phlebotomine sand flies. In this study, we report the results of Phlebotomine sand fly identification during the entomological surveillance conducted from 2017 to 2019. METHODS The northeastern plain of Italy was divided by a grid with a length of 15 km, and a CO2-CDC trap was placed in each geographical unit. The traps were placed ~ 15 km apart. For each sampling site, geographical coordinates were recorded. The traps were operated every two weeks, from May to November. Sand flies collected by CO2-CDC traps were identified by morphological and molecular analysis. RESULTS From 2017 to 2019, a total of 303 sand flies belonging to the species Phlebotomus perniciosus (n = 273), Sergentomyia minuta (n = 5), P. mascittii (n = 2) and P. perfiliewi (n = 2) were collected, along with 21 unidentified specimens. The trend for P. perniciosus collected during the entomological surveillance showed two peaks, one in July and a smaller one in September. Sand flies were collected at different altitudes, from -2 m above sea level (a.s.l.) to 145 m a.s.l. No correlation was observed between altitude and sand fly abundance. CONCLUSIONS Four Phlebotomine sand fly species are reported for the first time from the northeastern plain of Italy. Except for S. minuta, the sand fly species are competent vectors of Leishmania parasites and other arboviruses in the Mediterranean Basin. These findings demonstrate the ability of sand flies to colonize new environments previously considered unsuitable for these insects. Even though the density of the Phlebotomine sand fly population in the plain areas is consistently lower than that observed in hilly and low mountainous areas, the presence of these vectors could herald the onset of epidemic outbreaks of leishmaniasis and other arthropod-borne diseases in areas previously considered non-endemic.

Abstract
The Transphlebotomus subgenus has been drawing attention in last decade due to the uncertain vector capacity and cryptic life history of the group. During a 2015 entomological survey, Phlebotomine flies were collected in western locations of Slovenia, with a total of 22 specimens of the Transphlebotomus subgenus collected. In addition to morphological identifications, we confirmed the presence of Phlebotomus mascittii Grassi, 1908 (Diptera: Psychodidae) by nucleotide sequences of the mitochondrial cytochrome b gene. During the study, we found that P. mascittii is most abundant in the area of coastal-karst region of Slovenia, while in rare occasions can also be collected in Northeastern part of the country, near the Austrian border. Vector competence of P. mascitii, like all other member species of the Transphlebotomus subgenus, is unclear, but potential to transmit Leishmania (Kinetoplastida: Trypanosomatidae) pathogens or phleboviruses is strongly suspected.

Abstract
Cutaneous leishmaniasis (CL) is highly endemic in the Cukurova region, located on the crossroads of main refugee routes from the Middle East to Europe on the eastern Mediterranean part of Turkey. Our purpose was to investigate the phenotypic variation of Phlebotomus tobbi, the known vector of CL in the region, during one active season. Sand flies and microclimatic data were collected monthly from May to October, 2011, from five locations in six villages in the study area. A geometric morphometric approach was used to investigate wing morphology. Shape analyses revealed that males collected in May and June comprised one group, while specimens collected in August, September, and October formed a second group. Specimens from July were found to be distributed within these two groups. A similar distribution pattern was observed for females, but specimens from October were represented as the third district group. Significant size variation was detected for both sexes between months. Wing size and temperature were negatively correlated for females, but there was no temperature effect for males. Wing size of both sexes was increased in correlation to increasing relative humidity. Males were found to have smaller wings with increasing population density.

Abstract
Species identification of sandflies is mainly performed according to morphological characters using classical written identification keys. This study introduces a new web-based decision support tool (sandflyDST) for guiding the morphological identification of sandfly species present in Anatolia and mainland Europe and classified in the Phlebotomus and Sergentomyia genera (both: Diptera: Psychodidae). The current version of the tool consists of 111 questions and 36 drawings obtained from classical written keys, and 107 photographs for the quick and easy identification of 26 species of the genus Phlebotomus and four species of the genus Sergentomyia. The tool guides users through a decision tree using yes/no questions about the morphological characters of the specimen. The tool was applied by 30 individuals, who then completed study questionnaires. The results of subsequent analyses indicated that the usability (x‾SUSScore=75.4) and users' level of appreciation (86.6%) of the tool were quite high; almost all of the participants considered recommending the tool to others. The tool may also be useful in training new entomologists and maintaining their level of expertise. This is a dynamic tool and can be improved or upgraded according to feedback. The tool is now available online at http://parasitology.ege.edu.tr/sandflyDST/index.php.

Abstract
Morphological variations were observed in specimens of the sand fly species Sergentomyia bailyi Sinton 1931 collected from Pondicherry Union Territory, India. Examination of morphological characteristics showed differences in the length of sensilla chaeticum on antennal flagellomere 3 (A3) in males and females, in the size and shape of the spermathecae in females, and in the position of accessory spines on the gonostyle of males. In our previous study, DNA barcoding characterization of this sand fly species collected from Pondicherry UT revealed molecular variations within the S. bailyi population. This study confirms the existence of a species complex within S. bailyi population at Pondicherry UT.

Abstract
The adult female of the sand fly species Martinsmyia minasensis (Mangabeira, 1942) is described, and the characters of the genus Martinsmyia Galati, 1995 are defined. We performed morphometric analyses on the spermatheca and wings, and present data on the geographical distribution of M. minasensis, as well as an identification key to females of this genus. The specimens were measured, drawn, photographed, and compared with the similar species M. oliveirai. It was possible to distinguish between M. minasensis and M. oliveirai based on differences found in the common and individual ducts of the spermatheca, as well as wing shape and size.

Abstract
Phlebotomine sandflies, vectors of Leishmania (Kinetoplastida: Trypanosomatidae) parasites that affect millions of people worldwide, breed in terrestrial biotopes. As immature stages are rarely accessible, the detection of their natural breeding sites is primarily based on findings of juvenile males with unrotated external genitalia. In males, permanent 180° rotation on the longitudinal body axis occurs soon after eclosion; however, no study has as yet addressed this aspect in detail. The present study describes the timing and duration of the rotation of male external genitalia in eight highly medically important sandfly species belonging to the genera Sergentomyia, Lutzomyia and Phlebotomus (all: Diptera: Psychodidae), kept under controlled laboratory conditions. The average duration of rotation was species-specific and varied from 12 h in Sergentomyia schwetzi to 33 h in Phlebotomus sergenti. Significant differences in rotation times were found among species, even between two closely related species of the subgenus Larroussius, Phlebotomus orientalis and Phlebotomus tobbi. The rotation of genitalia in all three studied genera was randomly oriented and similar numbers of clockwise and counter-clockwise events were observed. The study also addresses the effects of some external factors. In all species studied, rotation was not affected by the time of day of eclosion. Similarly, no differences in total rotation time were found between Phlebotomus papatasi males maintained at 25 and 20 °C, respectively. The present findings will assist in the search for natural breeding sites and in studies aimed at elucidating strategies for integrated sandfly and leishmaniasis control.

Abstract
The female of Phlebotomus (Anaphlebotomus) fertei Depaquit, Léger & Robert, 2002 is described from Madagascar. The spermathecae have separated ducts, a body with an enlarged-sclerified dilatation and a deriviated large bladder with thin walls and long head. P. fertei female has the following characters: long antennal segments, pharyngeal armature with small teeth and cibarium with 15 to 30 denticles, and very long legs. Its remarkable spermatheca is closely related to that of P. berentiensis. The status of P. (Anaphlebotomus) berentiensis (Léger & Rodhain, 1978) is revised into this paper. The female is redescribed and the male is described for the first time. The latter has an unusual antennal formula (2/III-XII), a cibarium with four teeth and about 30 denticles, no tuft of setae on the coxite, four spines on the style, including a very long proximal one. Males and females were linked to each other based on morphological and molecular characteristics (second internal transcribed spacer of the ribosomal DNA and ND4 gene of the mitochondrial DNA). The inclusion of these taxa into the subgenus Anaphlebotomus Theodor, 1948 is exclusively based on male characters as listed by Theodor (style with four spines, no basal lobe on the coxite, paramere with two or three branches). The very heterogeneous characters of the females do not allow their use for the definition of this subgenus, which is probably not homogeneous.

Abstract
The male of Phlebotomus (Anaphlebotomus) fontenillei n. sp. is described from Namoroka area (Madagascar). Its belongs to the subgenus Anaphlebotomus: style with four spines, coxite without basal process and paramere with two branches. It shares with P. berentiensis an original and exclusive antennal formula: 2/III-XII which distinguishes them from P. fertei. P. fontenillei n. sp. differs mainly from P. berentiensis by about 40 setae in tuft on the ventral face of the coxite, the length of the genital ducts and the position of the spines on the style. Sequence of the second internal transcribed spacer (ITS2) of the ribosomal DNA (rDNA) is very informative: the male of P. fontenillei n. sp. cannot be linked to the female of P. huberti (male unknown) regarding the size of amplified DNA fragment (459 bp versus 600 respectively) and the high degree of variability. There are few differences (10 mutations) between the sequences of P. fontenillei n. sp. and P. berentiensis which are closely related species.

Abstract
Phlebotomus (Paraphlebotomus) riouxi Depaquit, Léger & Killick-Kendrick (Diptera: Psychodidae) was described as a typological species based on a few morphological characters distinguishing it from Phlebotomus (Paraphlebotomus) chabaudi Croset, Abonnenc & Rioux. The naming of P. riouxi coincided with its incrimination as a rural vector of Leishmania tropica Wright (junior synonym: Leishmania killicki Rioux, Lanotte & Pratlong) in Tataouine governorate, an arid region of southern Tunisia. The current report finds insufficient evidence to incriminate either phlebotomine sandfly as a vector of L. tropica in North Africa. Phlebotomus riouxi was found not to have the characteristics of a phylogenetic or biological species, and therefore it is synonymized with P. chabaudi. Both taxa were recorded together for the first time in Tunisia, in Tataouine, where three of 12 males showed intermediate morphology and both sexes of each taxon were not characterized by specific lineages of the nuclear gene elongation factor-1α or the mitochondrial gene cytochrome b, for which a long 3' terminal fragment is recommended for phlebotomine phylogenetics. This case study indicates that the eco-epidemiology of leishmaniasis should focus more on identifying key components of vectorial transmission that are susceptible to interventions for disease control, rather than on defining sibling species of vectors.

Abstract
BACKGROUND & OBJECTIVES Zoonotic visceral leishmaniasis is caused by Leishmania infantum, which is transmitted to humans by bites of phlebotomine sandflies and is one of the most important public health problems in Iran. To detect and identify the Leishmania parasites and their corresponding vector(s), an investigation was carried out in Azarshahr County, a new and important focus of the disease in East Azerbaijan province in northwestern Iran during late April to late October 2010. METHODS Sandflies were sampled using sticky papers (A4 white paper soaked in castor oil) from inside and outside of the houses and animal shelters, close to the vegetation and crevices. The head and three last abdomen segments of the specimens were removed and mounted in Puri's medium for species identification. The rest of body was subjected to molecular methods for detection of leishmanial parasites. RESULTS Among 400 female sandflies tested by polymerase chain reaction (PCR) of kDNA, ITS1-rDNA, and CPB genes of the parasite followed by restriction fragment length polymorphism (RFLP), only 2 out of 8 Phlebotomus tobbi were positive to L. infantum parasites. CONCLUSION The results indicated that, P. tobbi was the only species found infected by L.infantum and the principal vector of the disease agent to human.

Abstract
Morphological and molecular characterization of Phlebotomus (Larroussius) perniciosus Newstead and Phlebotomus (L.) longicuspis Nitzulescu in Tunisia is reported. Different localities in central and southern Tunisia were sampled. Sand flies were collected by sticky-paper traps and Center for Disease Control traps. For morphological study of males, the copulatory valves (aedeagi) were examined and the number of coxite hairs was recorded. For molecular analysis, the mitochondrial cytochrome b gene and the cytochrome c oxidase I gene were sequenced to investigate the population structure of P. perniciosus and P. longicuspis. The majority of P. perniciosus samples from southern and some specimens from central Tunisia showed single-pointed aedeagi curved at their apicies that were indistinguishable from the P. longicuspis aedeagi and appeared similar to the atypical morph of P. perniciosus, previously described in northern Morocco. The current study gives evidence of a wide distribution of atypical morphs of P. perniciosus in southern and central Tunisia.

Abstract
Phlebotomus (Phlebotomus) papatasi (Scopoli) collected in human dwellings from an agricultural villages Chaura, located in Gaya district, Bihar, India, showed morphological and anatomical variations. Male sand flies of this species exhibited variations in the genital structures, while females showed differences in the spermathecae and antenna segment three (A3). When the mitochondrial DNA of both male and female P. (P.) papatasi sensu lato population subjected to DNA barcoding, both the sexes of P. (P.) papatasi variants were found to be associated. The differences in the morphometric characteristics clearly constitutes preliminary evidence for infraspecific variation in P. (P.) papatasi s.1. population in India.

Abstract
The transmission of cutaneous leishmaniasis (CL) is of public health concern in Sri Lanka. The parasite Leishmania donovani is reported to be the causative agent for CL in Sri Lanka. However there is no report on the vector of CL in the country. Phlebotomus argentipes sensu lato is the well known vector of L. donovani which causes visceral leishmaniasis (VL) in the nearby South India. The taxon Ph. argentipes previously reported to occur as a species complex comprising of two morphospecies namely A and B. The taxonomy of the Argentipes complex was reassessed recently and reported to have three species viz. Phlebotomus glaucus, Ph. argentipes sensu stricto and Ph. annandalei. A study was carried out in Jaffna mainland, where three CL patients have been recorded, and two associated islands in northern Sri Lanka to record the presence of the members of the Argentipes complex. Sandflies were collected using human landing and cattle baited collections. Collected samples were analyzed based on reported morphometric and meristic characteristics. The study revealed the presence of all three members of the complex in which Ph. glaucus and Ph. argentipes s.s. are reported for the first time in Sri Lanka.

Abstract
Populations of Phlebotomus major were examined in two endemic and nonendemic foci of visceral leishmaniasis in Iran. Based on the shape of the aedeagus and ventrally located hairs of coxite and pharyngeal armatures, two morphotypes were found sympatrically in the endemic area of Borazjan. Significant differences in morphometric survey were observed in at least 11 measured characters. The aedeagus of the non-endemic Miyandoab morphotype, and also of a few specimens from Borazjan, is completely parallel throughout its length with a slightly expanded end. Ventrally located hairs of the middle coxite were longer and more compact. It is close morphologically to P. major neglectus (P. neglectus), which was recently recorded from Iran. It is also morphologically similar to P. notus, which has not yet been reported from Iran and needs further investigation. The aedeagus of the morphotype occurring only in Borazjan is narrower in the middle and the hairs are closer to the base of the coxite and are shorter and more outspread, which makes it similar to P. major krimensis or P. neglectus. The two morphotypes occurring sympatrically in Borazjan do not appear to be subspecies and it may be premature to propose them as separate species. Further investigation is needed to clarify the actual status of P. major s. l. in Iran.

Abstract
The closely related sandfly species of the subgenus Phlebotomus namely, Phlebotomus papatasi (Scopoli, 1786), Phlebotomus duboscqi Neveu-Lemair, 1906 and Phlebotomus bergeroti Parrot, 1934 (Diptera: Psychodidae), are major vectors of Leishmania major (Kinetoplastida: Trypanosomatidae), the causative agent of cutaneous leishmaniasis in the Old World. Although allopatric in most of their distribution, the three species exist sympatrically in many places in central and eastern Sudan. Males of the three species can be distinguished using morphological characters; however, females are much harder to identify, thus complicating epidemiological studies. We carried out a morphometric and a molecular study to determine reliable morphological features and develop a polymerase chain reaction (PCR) assay for distinguishing females of these species. Males and females from each species were collected from sites in Sudan, East Africa and from one site in Mali, West Africa. Males were analysed morphologically and 20 characters and 10 character ratios were used in a stepwise discriminant analysis. This led to the identification of four characters with high discriminant loading scores sufficient for accurate male species identification. Male DNA was then used for the development of a PCR-based species diagnostic based on the second internal transcribed spacer (ITS2) of the ribosomal DNA. A set of four primers was developed to generate fragment sizes that are specific to each species and can reliably identify females as well as hybrid DNA. Both the morphometric and the molecular findings of this study have important applications for studies of the epidemiology of cutaneous leishmaniasis.

Abstract
The taxonomic status of the sand fly Phlebotomus (Euphlebotomus) argentipes Annandale & Brunette 1908, which transmits Leishmania (Leishmania) donovani (Laveran & Mesnil 1903) in southern Asia, is reassessed, because variation in morphology, behavior, and distribution suggests it to be a complex of sibling species. The putative complex is composed of the nominotypical member Phlebotomus argentipes sensu stricto, Phlebotomus annandalei Sinton 1923 status revived and Phlebotomus glaucus Mitra & Roy 1953 new status. An allolectotype is designated for the female of P. argentipes as well as neotypes for the males of P. annandalei and P. glaucus. Morphological descriptions, illustrations, and keys are presented to allow identification of adult males and females. Based on female morphological characters, P. argentipes s.s., P. annandalei and P. glaucus can be distinguished from each other using principal component analysis. P. glaucus is widespread in India, occurring sympatrically with P. argentipes s.s. in L. donovani-endemic foci, whereas P. annandeli is peripatric to the type species in Chennai, southern India. "In copula" is a process of postcopulatory sexual selection occurring as correlated coevolution of male and female reproductive traits, which drives species isolation. This pattern has been implicated in reproductive isolation among the members of the P. argentipes complex. Further research on adult behavior and larval biology of the P. argentipes complex is needed to understand the epidemiology and control of visceral leishmaniasis.

Abstract
In female phlebotomine sandflies, little is known about the reproductive accessory glands that presumably contribute to egg production and/or oviposition. The main protein secreted in the accessory glands of female Phlebotomus papatasi was recently characterised as a lipase-like protein, the first to be found in the female accessory glands of any insect. This protein, named PhpaLIP (for Phlebotomus papatasi lipase), has now been detected and localized in the reproductive tissues of female P. papatasi, at different stages of the gonotrophic cycle, using a polyclonal anti-PhpaLIP serum and both confocal scanning laser and immuno-electron microscopy. PhpaLIP appears to be always present in the accessory glands (with a secretory peak shortly before oviposition) but was also detected in the follicle cells of the ovarioles, within the developing vitelline envelope, and in the oviducts. The results are discussed in relation to the functions that PhpaLIP could have during the gonotrophic cycle, in the various reproductive structures of female P. papatasi.

Abstract
A comparative morphological and molecular study was carried out on 11 different populations of Phlebotomus (Paraphlebotomus) caucasicus Marzinovsky 1917 caught in 7 provinces in Iran (2004-2005). Differences in the implantation level of the two distal spines of the style, the number of setae of the basal lobe of coxite, and the length of the third antennal segment, revealed the existence of two morphotypes within P. (Pa) caucasicus, a species having a confused history if we take into account an unclear synonymisation with Phlebotomus (Paraphlebotomus) grimmi Porchinsky 1874. Sequencing of mtDNA (a fragment of cytchromeB gene, tRNA for serine gene and a fragment of NADH1 gene) and Neighbour-Joining analysis showed a partial correlation between morphotypes and haplotypes. We also found a correlation between the latter and the geographical origin of the specimens. These results need further studies in order to appreciate the role of each morphotype/haplotype in the transmission of Leishmania major.

Abstract
A new species of sandfly is described from limestone caves in Thailand. The inclusion of this species in the subgenus Euphlebotomus is justified on the basis of characters of the male genitalia (paramere, basal lobe). The male-female gathering in the same taxon is based on ecological (cavernicolous species), morphological (length of male genital filaments and female spermathecal ducts) and molecular (homology of cytochrome b mt DNA sequences) criteria. A differential diagnosis between Phlebotomus mascomai n. sp. and P. argentipes Annandale & Brunetti, the vector of Leishmania donovani (Laveran & Mesnil) in India, is proposed based on several morphological characters like antennal formula and genitalia.

Abstract
The capture of a new species of the subgenus Migonemyia Galati, 1995 (Diptera, Psychodidae, Phlebotominae), Migonemyia vaniae sp. nov. in the Ribeira Valley, state of São Paulo, Brazil, together with the other two species: Mg. migonei (França, 1920) and Mg. rabelloi (Galati & Gomes, 1992) lead us to review this subgenus. The new species was described and illustrated. The genitalia of the two other species were also illustrated and some genital characteristics (number of setae on the gonocoxite tuft, ejaculatory ducts and pump and ducts/pump ratio; and number of setae on the tergite VIII of the females) considered important to differentiate the three species, including five populations of Mg. migonei (from Northeastern, Southeastern, and Southern Brazilian regions and of Peru) were submitted to variance analyses. The Mg. migonei population of Northeastern Brazilian region showed distinct smaller values (P < 0.05) than the other Brazilian populations studied as regarding these characteristics. The capture of both sexes of these three species in sympatry confirms the association between the sexes of Mg. rabelloi, recognised as doubtful when this species was originally described. Identification keys for male and female of the three species are presented.

Abstract
An intraspecific study on the morphological and molecular characteristics of Phlebotomus sergenti s.l., the main vector of Leishmania tropica, was performed on 28 Iranian populations from 11 provinces and a few samples from Greece, Morocco, Lebanon, Turkey, Pakistan, and Syria. Three morphotypes were identified as A, B and C, with some intermediate forms in the samples under investigation. Based on the number of setae and the width of basal lobe of coxite, differences between A and B morphotypes were highly significant. Excluding one unusual haplotype, sequence analysis of approximately 439 bp of mtDNA (a fragment of cytochrome B gene, tRNA for serine gene, and a fragment of NADH1 gene) revealed a 6-7% genetic distance within the Iranian populations and among the specimens of other countries. Neighbor-Joining (NJ) analysis confirmed the existence of three main groups within our samples. Although there was no consistency between morphotypes and genotypes, but an interrelationship was found between morphometry and morphotypes. Morphotype A, which was considered as P. sergenti sergenti, was the most prevalent in collection sites. Morphotype B, which was identified as Phlebotomus sergenti similis, is the first record of this subspecies in Iran, and was found to be sympatric with other morphotypes. Morphotype C had an elongated style in comparison with P. sergenti sergenti. Molecular database showed three main genetic structures. This is the first combined morphological and molecular studies on P. sergenti s.l. in Iran.

Abstract
For the first time, dissection and microscopical examination of several specimens of Chinius junlianensis Leng 1987 have revealed the antennal and palpal formulae of both males and females of this species and the true morphology of the spermathecae in the females. The latter have smooth elongated reservoirs and a very long common duct, which matches the long genital filaments of the males. There are no setae on the mesanepisternum, a feature shared with another 'primitive' genus, Warileya, and with Sergentomyia.

Abstract
The female of Phlebotomus chadlii Rioux, Jumminer & Gibily, 1966 is described and illustrated for the first time from a specimen collected in El Kef region, northwest Tunisia. It was distinguished from P. ariasi by several characters of the spermathecae: 1) the enlarged portion of P. chadlii spermathecae duct appears smooth and better developed than that of P. ariasi; 2) in P. chadlii, this part comprises three quarters of the duct whereas, in P. ariasi, it covers only the half; 3) the spermathecae neck of P. chadlii is shorter than that of P. ariasi. The duct base is compatible with the large aedeagus size of P. chadlii male. Besides, the assignment of this female to the species P. chadlii is supported by: 1) the presence of males in the same area, over the last three years; 2) the total absence in this area of P. ariasi; 3) the concomitant presence, in the same trap station, of the described female with P. chadlii males.

Abstract
Phlebotomus sergenti populations from different areas of the Mediterranean basin are known to exhibit high intraspecific variability. Previous studies of ITS2 revealed the presence of two branches that may represent sibling species. To corroborate this finding by other tools, two colonies of P. sergenti originating from Turkey and Israel, each belonging to a different ITS2 branch, were compared by three different methods: geometric morphometric analysis of wing shape, RAPD (random amplified polymorphic DNA), and cross-mating study. For geometric morphometric analysis, two-dimensional Cartesian coordinates of 16 landmarks from the wings were digitized and analyzed. Significant shape differences were found between colonies but not between sexes within each colony. RAPD results formed two distinctive clades corresponding to the origin of the colony but also showed heterogenity among members of both colonies. In cross-mating studies, viable hybrid F1 and F2 progeny were obtained when both Turkish males/Israeli females and Israeli males/Turkish females were crossed. F1 progeny was included in RAPD analysis and these hybrids formed a distinctive clade with an intermediate position between the two parental clades. No significant differences were found in egg production of crossed sand flies. The cross-mating study showed that there is no reproductive barrier between P. sergenti from different geographical areas. On the other hand, RAPD and geometric morphometric analysis revealed a significant difference between colonies and confirmed the suitability of previous ITS2 analysis for discrimination among sand fly populations. Further development of molecular markers should resolve a possible existence of sibling species within Phlebotomus sergenti.

Abstract
The spermathecal complex of Phlebotomus papatasi Scopoli (Diptera: Psychodidae) undergoes histological and physiological changes during its gonotropic cycle. The present histochemical study revealed a mucopolysaccharide secretory mass in the spermathecae of the newly emerged sandfly. Sperm competition occurs when two or more males compete to fertilize an ovum in the female reproductive tract. In this study, spermatophores of two or more competing males were deposited at the base of the spermathecal ducts, which originate from the female bursa copulatrix. This suggests that females play a role in sperm displacement, which is defined as any situation in which the last male to mate with a female fertilizes maximum number her eggs. A blood meal ingested by the female for ovary development and egg laying stimulates the release of sperm from the spermatophore. The spermatozoa then migrate to the lumen of the spermatheca. The ultrastructure of spermatozoa comprises a head with double-layered acrosomal perforatorium, an elongate nucleus, and the axoneme with a 9 + 9 + 0 flagellar pattern. This axomene differs from the flagellate axoneme of other Psychodinae. Morphological changes, such as the casting off of the acrosomal membrane, and histological changes in the spermatophore are also described. Mating plugs that have been described previously in sandflies appear to be artefacts. Females of P. papatasi may be inseminated more than once during each gonotrophic cycle, and additional inseminations may be necessary for each cycle. The relationships between the volumes of the sperm and the spermatheca were calculated to determine sperm utilization and fecundity of P. papatasi. As the females of P. papatasi mate polyandrously, the anatomical and physiological complexity of the spermathecal complex may be related to post-copulatory sexual selection.

Abstract
Females of phlebotomine sandflies (Diptera: Psychodidae) possess highly variable spermathecae that present several important taxonomic characters. The cause of this diversity remains a neglected field of sandfly biology, but may possibly be due to female post-mating sexual selection. To understand this diversity, a detailed study of the structure and function of the spermathecal complex in at least one of the species was a prerequisite. Using scanning and transmission electron microscopy, described here is ultrastructure of the spermathecal complex in the sand fly, Phlebotomus papatasi Scopoli. The spermathecal complexes are paired; each consists of a long spermathecal duct, a cylindrical spermathecal body, and a spherical spermathecal gland. Muscle fibres, nerves, tracheoles, and vascular sinuses connect the spermathecal body and duct through the epithelial layers. Spermathecal gland is formed by a typical insect epidermis and consisting of an epithelial layer of class-1 epidermal cells and elaborate glandular cells of class-3 epidermal cells, each having both receiving and conducting ductules (i.e. "end apparatus") and a "cytological apodeme", which is a newly described cell structure. The spermathecal body and duct are lined by class-1 epidermal cells and a cuticle, and are enveloped by a super-contracting visceral muscular system. The cuticle consists of rubber-like resilin, and its fibrillar arrangement and chemical nature are described. A well-developed neuromuscular junction exists between the spermathecal gland and the spermathecal body, which are connected to each other by a nerve and a muscle. The spermathecal complexes of the sandfly are compared with those of other insect species. The physiological role and possible evolutionary significance of the different parts of spermathecal complex in the sandfly are inferred from the morphology and behaviour. Post-mating sexual selection may be responsible for the structural uniqueness of the spermathecal complex in phlebotomine sandflies.

Abstract
Between the April and October of 1997, the sandflies in six areas (Centrum, Altinekin, Kadinhani, Cumra, Beysehir and Bozkir) of the Turkish province of Konya, in Central Anatolia, were surveyed. All the sandflies were caught close to houses, on sticky-paper traps placed in barns used by livestock. All 127 specimens of Sergentomyia collected were either S. theodori (86.6%) or S. dentata (13.4%). The other 2017 sandflies caught represented 12 species of Phlebotomus - mostly P. papatasi (78.4%) or P. halepensis (10.9%), with P. sergenti (3.8%), P. simici (2.2%), P. kandelakii (1.6%), P. similis (0.9%), P. jacusieli (0.5%), P. neglectus (0.4%), P. transcaucasicus (0.3%), P. syriacus (0.3%), P. kyreniae (0.3%) and P. balcanicus (0.3%) relatively rare. Most (87%) of the flies were male. This represents the first report of P. transcaucasicus in Turkey. In addition, P. syriacus, P. neglectus, P. similis and S. dentata have not been detected before in Central Anatolia.

Abstract
During a brief entomological survey carried out in Ouagadougou, Burkina Faso, in March 2002, 178 phlebotomine sand flies (Diptera, Psychodidae) were caught using CDC miniature light traps. They were identified as Phlebotomus duboscqi Neveu-Lemaire, P. longicuspis Nitzulescu, Sergentomyia adleri (Theodor), S. affinis vorax (Parrot), S. antennata (Newstead), S. bedfordi (Newstead), S. christophersi (Sinton), S. fallax (Parrot), S. magna (Sinton) and S. schwetzi (Adler, Theodor & Parrot). This is the first record south of the Sahara of P. longicuspis sensu lato. This proven vector of Leishmania infantum Nicolle is a species closely related to P. perniciosus. It was identified by morphology and by the sequencing of a fragment of mitochondrial cytochrome b. There was 100% sequence homology with typical Tunisian specimens, and all characters identified the specimen as P. longicuspis sensu stricto. Epidemiological and biogeographical consequences are discussed.

Abstract
This work is the fourth related to species recently described from Madagascar. The authors describe Sergentomyia goodmani on females and males. The female has tubular spermathecae with internal spines. It has an aspect, in Canada balsam, of transversally striped spermatheca, without being completely segmented. The spermathecal ducts share a proximal common part. The pharynx is narrow. The cibarial armature is comb-like. Based on these characters, the authors consider that S. goodmani belongs to the subgenus Rondanomyia. They reinstate this subgenus and consider Neophlebotomus sensu Lewis, 1977 as invalid. Considering Grassomyia as a genus, this is the first record of Sergentomyia in Madagascar.

Abstract
Morphological variations were observed in Phlebotomus argentipes, the vector for visceral leishmaniasis reported from the endemic states of Bihar, West Bengal and Uttar Pradesh. The taxonomic features distinguishing vector and nonvector species of P. argentipes were relative length of ascoid and antennal segment IV. Three morphotypes were characterized as <0.4, = 0.4 and >0.4 respectively. Other characteristics of wing width, wing length, eye, style, antennal segment III, IV, V was found statistically significant (p<0.05) and eleven other morphological measurements were not significant. This study suggests three different morphotypes of P. argentipes in these three endemic states. The genetic and reproductive isolation among such morphotypes will establish the variability in further studies.

Abstract
Four populations of the phlebotomine sandfly Phlebotomus (Phlebotomus) papatasi (Scopoli) (Diptera: Psychodidae), in different ecoregions at altitudes between 368 and 1117 m in the Sanliurfa Province of Turkey, were compared using morphometric and isoenzyme analyses. A similarity phenogram obtained from allozyme data showed that heterozygosity was extremely low, particularly for the alleles which were found to be completely fixed in populations at Hamdun (HMD) and Alitas (ALT). Populations at Akcakale (AKL) and ALT branched as a separate group from populations at Hayatiharrani (HHR) and HMD. The ALT population at the highest altitude (1117 m), and the HHR population (488 m) were clustered distinctly when linear measurements of 46 morphological characteristics were examined. A UPGMA (unweighted pair-group method using arithmetic averages) phenogram also showed that ALT and HHR clustered separately, whereas AKL and HMD formed another group.

Abstract
Phlebotomus sergenti was identified morphologically in samples from three Moroccan foci of leishmaniasis caused by Leishmania tropica in the provinces of Azilal, Essaouira and Taza. Three primary mitochondrial DNA lineages were identified, and they could be markers for regionally distributed cryptic species. Greater mitochondrial diversity in Azilal indicated that this central province could have been the origin of dispersal of P. sergenti or the zone of secondary contact. All except one of the 21 mitochondrial haplotypes showed a marked regional distribution, and this indicates that vector control would not always be followed by rapid, long-distance reinvasion. Only mitochondrial haplotype SER18 was a putative marker for long-distance dispersal, for which there is no evidence of human assistance.

Abstract
The bloodsucking adult females of Phlebotomus perniciosus Newstead and P. longicuspis Nitzulescu (Diptera: Psychodidae) are important vectors of the protozoan Leishmania infantum Nicolle (Kinetoplastida: Trypanosomatidae) in western Mediterranean countries. The species status of the two phlebotomine sandflies was assessed, along with the epidemiological implications. Individual sandflies from three Moroccan Rif populations were characterized morphologically, isoenzymatically (by the isoelectrofocusing of alleles at the polymorphic enzyme loci of HK, GPI and PGM), and by comparative DNA sequence analysis of a fragment of mitochondrial Cytochrome b (mtDNA). By reference to the character profiles of specimens from other locations, including southern Spain and the type-locality countries, the Moroccan flies were placed in three lineages: first, the lineage of P. perniciosus, which contained two mtDNA sublineages, one (pnt) widely distributed and associated with the morphology of the male types from Malta, and the other (pna) associated with a P. longicuspis-like male morphology; second, the lineage of P. longicuspis sensu stricto, including typical forms from Tunisia; and third, a new sibling species of P. longicuspis. The mtDNA sublineage (pnt) of typical P. perniciosus was also found in some P. longicuspis from Morocco, indicating interspecific hybridization. The typical race of P. perniciosus occurs in Italy as well as in Malta, Tunisia and Morocco. It is replaced in southern Spain by the Iberian race (with the pni mtDNA sublineage). The discovery of interspecific gene introgression and a new sibling species mean that previous records of the two morphospecies do not necessarily reflect their true vectorial roles or geographical and ecological distributions.

Abstract
An entomological study was made in order to complete the epidemiological data on leishmaniasis in Lebanon. 19 species of sandflies (13 of the genus Phlebotomus and six of the genus Sergentomyia) were found. The list includes a recently described species of the Synphlebotomus subgenus (P. saltiae) and eight other species mentioned for the first time in Lebanon: P. neglectus, P. brevis, P. langeroni, P. balcanicus, S. fallax, S. taizi, S. tiberiadis and S. christophersi. Ecological records of each species and its possible involvement in Leishmania transmission are discussed.

Abstract
Leishmaniasis in the Old World is vectored by phlebotomine sandflies of the genus Phlebotomus. In a survey of sandflies in Jeddah area carried out by sticky traps and CDC light traps, three species were identified. These were P. papatasii, P. bergeroti and P. alexandri. The diagnostic morphology was illustrated. The results were discussed.

Abstract
The authors carried out isoenzyme characterization and genotype comparison studies for Phlebotomus chinensis and Phlebotomus sichuanensis images collected from their holotype/paratype original localities: West Mountain, West Suburb, Beijing and Lixian County, Sichuan Province. Numerical analysis was carried out and the dendrogram of four species of Adlerius was drawn up according to morphological characteristics of these four species. The results showed that P. chinensis and P. sichuanensis can be identified enzymatically in PGM and the MDH-2 allele also differs in P. chinensis from Beijing and. P. sichuanensis. The dendrogram of four Adlerius species showed that P. fengi and P. longiductus are very similar and they clustered first, then P. sichuanensis combine with them to form a combined group. P. chinensis is a separate group from other three. These two groups come to combine at last. Above results have proved that P. sichuanensis is an isolate species instead of a so-called large type P. chinensis.

Abstract
First record of Phlebotomine sandflies belonging to the genus Phlebotomus from Madagascar. Description of two new species: Phlebotomus (Anaphlebotomus) fertei n. sp. from three males and Phlebotomus (Anaphlebotomus) huberti n. sp. from two females. Their belonging to the subgenus Anaphlebotomus is supported by several characters. Male have four spines on the style, a coxite without basal tubercle, a paramere with two branches, one to three antero-inferior setae on the mesanepisternum. Female, closely related to the Asiatic species of the same subgenus, has a characteristic pharyngeal armature, about ten cibarial teeth, and annealing spermathecae with long ducts including a short basal common part. These two taxa differ by variation in the second internal transcribed spacer (ITS2) of the ribosomal DNA (rDNA). At the present time, the subgenus Anaphlebotomus includes six species (excluding P. fortunatarum from it), completing the known species from Africa (P. rodhaini and P. rousettus) and from Asia (P. stantoni and P. colabaensis).

Abstract
Phlebotomus papatasi sand flies, the vectors of Leishmania major, differ genetically in their susceptibility to the pathogens. The costs of infection appear to be so great that selection against Leishmania-susceptible flies could presumably occur, unless susceptibility is compensated for by some advantage. Foci of P. papatasi-transmitted L. major are mainly found in arid habitats where seasonal stress of dehydration and heat reduces the quantity of sugar in plant leaves. The sand flies feed on these leaves and with the lack of essential sugar only a few survive long enough to deposit eggs and transmit Leishmania. This association suggested that susceptibility to L. major infection may be linked with advantageous tolerance of sugar deprivation. Here we show that desert sand flies, provided with excess sugar, became progressively resistant to infection. Selection for survival under sugar-poor conditions increased the susceptibility of parent and first-generation offspring by more than 2-fold. The leaves of plants, on which flies naturally feed, contain more sugar in irrigated than in arid habitats. About 85% of first-generation flies colonized from a desert habitat retain experimental Leishmania infection compared to 25 % of offspring of flies from irrigated sites.
