Description of Sergentomyia phadangensis n. sp. (Diptera, Psychodidae) of Thailand.

ABSTRACT: Since 1996, there are emerging autochthonous cases of leishmaniasis in Thailand due to Leishmania "siamensis" and to L. martiniquensis explaining a recent interest for the sand fly fauna where Sergentomyia gemmea and Se. barraudi have been considered possible vectors in the country.Field studies were undertaken in a cave of Phitsanulok Province, Thailand. Phlebotomine sandflies have been studied morphologically and some have been processed for molecular biology (sequencing of cytB rDNA).A new species of sand fly, belonging to the genus Sergentomyia: Se. phadangensis n. sp., is described. The association of the male and female is supported by the homology of the sequences of cytochrome b rDNA.The description of a new species in Thailand is of importance in view of the existence of autochthonous leishmaniases.

Phlebotomus (Euphlebotomus) barguesae n. sp. from Thailand (Diptera - Psychodidae).

Project description:BackgroundA few studies have been carried out on the Phlebotomine sandflies from Thailand. Within the Phlebotomine sandflies, the genus Phlebotomus Rondani & Berté, 1840 contains the vectors of leishmaniases in Europe, Africa and Asia. It includes several subgenera. Among them the subgenus Euphlebotomus Theodor, 1948 contains at the present time 12 taxa. The type-species of this subgenus is P. argentipes Annandale & Brunetti, 1908, the vector of Leishmania donovani (Laveran & Mesnil, 1903) in India.ResultsA new species of sandfly, P. barguesae n. sp. is described from limestone caves in Thailand. The male-female gathering in the same species is based on ecological, morphological and molecular criteria (homology of mtDNA cytochrome c oxidase I sequences). The inclusion of P. barguesae n. sp. in the subgenus Euphlebotomus is justified on the basis of characters of the male genitalia (five spines on the style, bifurcated paramere, and no basal lobe on the coxite) and of female pharyngeal armature (two kinds of teeth). It well differenciated from another sympatric species: P. mascomai.ConclusionThe new species described in the present study has smooth spermathecae. This original morphology opens a discussion on the heterogeneity of this subgenus.

First record of Phlebotomine sandflies (Diptera: Psychodidae) in the Comoros Archipelago with description of Sergentomyia (Vattieromyia) pessoni n. sp. and S. (Rondanomyia) goodmani comorensis n. ssp.

Project description:No Phlebotomine sandflies had ever been reported in the Comoros Archipelago, including the three islands of the Republic of the Union of Comoros (Grande Comore, Mohéli and Anjouan) and the French oversea department of Mayotte. During three field surveys carried out in 2003, 2007 and 2011, we provided the first record of Phlebotomine sandflies in this area. A total of 85 specimens belonging to three species were caught: a new species S. (Vattieromyia) pessoni n. sp. (two females from Grande Comore), a new subspecies of Sergentomyia (Rondanomyia) goodmani (80 specimens from Grande Comore and one from Anjouan) and Grassomyia sp. (two females from Mohéli). The individualisation of these taxa was inferred both from morphological criteria and sequencing of a part of the cytochrome b of the mitochondrial DNA. These taxa are closely related to Malagasy sandflies.

Description of the sandfly species Chinius samarensis n. sp. (Psychodidae; Diptera) from the Philippines.

Project description:The authors have described Chinius samarensis n. sp. (Diptera; Psychodidae) from the Philippines (Island of Samar). This is the fourth known species belonging to the Asiatic genus Chinius Leng, 1987. Like the other Chinius, C. samarensis n. sp. is a cavernicolous species. The genital ducts of the male are four times shorter than the spermathecal ducts. However, the authors think that male and female belong to the same species due to their similar cytochrome b mt DNA sequences. A differential diagnosis with the other species belonging to the genus Chinius is provided.

Paraphyly of the subgenus Sintonius (Diptera, Psychodidae, Sergentomyia): status of the Malagasy species. Creation of a new subgenus and description of a new species.

Project description:During an inventory of Phlebotomine sand flies carried out in Madagascar, we have identified some specimens showing morphological characters related to the subgenus Sintonius of the genus Sergentomyia. We started a molecular study based on cytochrome b mtDNA and on D1-D2 and D8 domains of the rDNA. The sampling includes all the Sergentomyia species available and also S. (Sergentomyia) schwetzi, S. (Parrotomyia) magna, and the following species belonging to the subgenus Sintonius: S. clydei, S. christophersi, S. affinis vorax, S. adleri and S. meilloni. The Sintonius subgenus (sensu Theodor) is paraphyletic. The Malagasy specimens morphologically Sintonius-like are never clustered with the continental Sintonius. We propose a new subgenus to include them: Trouilletomyia subg. nov. Due to the lack of mesanepisternal setae, the species huberti is removed from the genus Phlebotomus and we propose here a new combination: Sergentomyia huberti comb. nov. The male of S. huberti is pinpointed and described for the first time. Lastly, a new species for Science is described on one female: Sergentomyia (Trouilletomyia) boironis n. sp.

Sand fly fauna of Crete and the description of Phlebotomus (Adlerius) creticus n. sp. (Diptera: Psychodidae).

Project description:BackgroundThe Greek island of Crete is endemic for both visceral leishmaniasis (VL) and recently increasing cutaneous leishmaniasis (CL). This study summarizes published data on the sand fly fauna of Crete, the results of new sand fly samplings and the description of a new sand fly species.MethodsAll published and recent samplings were carried out using CDC light traps, sticky traps or mouth aspirators. The specific status of Phlebotomus (Adlerius) creticus n. sp., was assessed by morphological analysis, cytochrome b (cytb) sequencing and MALDI-TOF protein profiling.ResultsPublished data revealed the presence of 10 Phlebotomus spp. and 2 Sergentomyia spp. During presented field work, 608 specimens of 8 species of Phlebotomus and one species of Sergentomyia were collected. Both published data and present samplings revealed that the two most common and abundant species were Phlebotomus neglectus, a proven vector of Leishmania infantum causing VL, and Ph. similis, a suspected vector of L. tropica causing CL. In addition, the field surveys revealed the presence of a new species, Ph. (Adlerius) creticus n. sp.ConclusionsThe identification of the newly described species is based on both molecular and morphological criteria, showing distinct characters of the male genitalia that differentiate it from related species of the subgenus Adlerius as well as species-specific sequence of cytb and protein spectra generated by MALDI-TOF mass spectrometry.

Review of the Psychodinae from Mallorca, Spain, with description of Pericoma unipennata, sp. n. (Diptera, Psychodidae).

Project description:We review the Psychodinae of Mallorca, recognising fifteen species based on recent collections and available literature. Previously unpublished data is presented for eleven species, of which Neoarisemus ibericus Wagner, 1978, Mormia tenebricosa (Vaillant, 1954), Clogmia albipunctata (Williston, 1893), Lepiseodina rothschildi (Eaton, 1913), Paramormia ustulata (Walker, 1856), Philosepedon pyrenaicus Vaillant, 1974 and Psychoda (Psycha) grisescens Tonnoir, 1922 are first records for Mallorca. An old record of Pericoma trifasciata (Meigen, 1804) is considered doubtful. Pericoma unipennata sp. n is described and illustrated based on a male collected at Deía. Distributional data are reviewed for all newly recorded species. Based on the Psychodinae fauna, the zoogeographical affinities of Mallorca are briefly discussed.

Sand fly fauna of South-Eastern Romania, with the description of Phlebotomus (Transphlebotomus) simonahalepae n. sp. (Diptera: Psychodidae).

Project description:BackgroundAn entomological study was conducted in the Canaraua Fetii Special Protection Area in the Dobrogea region, South-Eastern Romania. Four sand fly species were recorded at this location between 1968 and 1970: Phlebotomus neglectus, Ph. balcanicus, Ph. sergenti and Sergentomyia minuta. The most abundant sand fly species recorded at that time were Ph. balcanicus and Se. minuta. In the context of a countrywide study to update the sand fly species diversity, we surveyed the same area, recording also a previously unknown Ph. (Transphlebotomus) sp., for which we provide a formal description here.MethodsSand flies were collected between July and August in 2018 and 2019 in three sites from Canaraua Fetii, Dobrogea region, Romania. The general aspect of the landscape is of a canyon (vertical, narrow walls and deep valleys). Species identification was done using both morphological and molecular analyses.ResultsOut of 645 collected sand flies, 644 (99.8%) were morphologically identified as Ph. neglectus, while one female specimen (0.2%) was assigned to a previously unknown species, belonging to the subgenus Transphlebotomus. The morphological and molecular examination of this specimen showed that it is a previously unknown species which we formally describe here as Phlebotomus (Transphlebotomus) simonahalepae n. sp. Also, Ph. balcanicus, Ph. sergenti, and Se. minuta (previously recorded in this location) were not present.ConclusionsThe study revealed for the first time the presence of sand flies of the subgenus Transphlebotomus in Romania. Moreover, a new species, Ph. simonahalepae n. sp., was described based on a female specimen, raising the number of species in this subgenus to six. In the investigated natural habitat, the predominant species was Ph. neglectus instead of Ph. balcanicus and Se. minuta (recorded as the predominant species in 1968-1970).

Morphological and DNA-based description of Trichophoromyia peixotoi n. sp. (Diptera: Psychodidae), a new sand fly species from the Brazilian Amazon.

Project description:BackgroundPhlebotomine sand flies of the genus Trichophoromyia Barretto, 1962 are of great relevance to public health as vectors of Leishmania protozoans. A new phlebotomine species named Trichophoromyia peixotoi n. sp. is here described based on both male morphology and COI DNA barcodes.MethodsThe sand fly specimens were collected in the Parque Nacional da Amazônia (PNA), situated in the municipality of Itaituba, state of Pará, Brazil. Morphological description was done based on 10 male specimens. Five specimens were DNA barcoded for the COI gene.ResultsThe morphological and molecular analyses allowed the delimitation of this new species from others of Trichophoromyia. Trichophoromyia peixotoi n. sp. is closely related to other species with aedeagal ducts > 4 times the length of the sperm pump, from which it may be distinguished by the gonocoxite bristles and paramere shape.ConclusionsThe description of T. peixotoi n. sp. brings the number of species of Trichophoromyia to 45, including 24 for Brazil. The integrative taxonomy effort through the analysis of COI barcodes proved to be effective in the species delimitation of some Trichophoromyia spp.

Phlebotomine sand flies from Madagascar (Diptera: Psychodidae). VII. An identification key for Phlebotomus with the description of Phlebotomus (Anaphlebotomus) vaomalalae n. sp.

Project description:An identification key of the Phlebotomus in Madagascar is proposed as well as the description of the male and female Phlebotomus (Anaphlebotomus) vaomalalae n. sp. from Mikea Forest in the south-west of Madagascar. The assignation of this new species to the genus Phlebotomus is based on the presence of mesanepisternal setae. Its inclusion in the subgenus Anaphlebotomus is based on the males on the presence of four spines on the style, the lack of a coxite basal process and the existence of a bifurcated paramere. The female has cibarial and pharyngeal armature and spermathecal architecture similar to Phlebotomus fertei and Phlebotomus berentiensis, two other Malagasy species which belong to Anaphlebotomus. Male and female are held to belong to the same species because of their morphological characters, the homology (100%) of their partial cytochrome b mtDNA sequences and their capture in the same trap. P. vaomalalae n. sp. is a small species compared to the other Phlebotomus species of Madagascar. The cibarium of the male and the female of P. vaomalalae n. sp. is armed with teeth, like those of other Malagasy Phlebotomus. However, it differs in the arrangement and shape of the respective teeth and denticles. The male of P. vaomalalae n. sp. looks like that of P. fontenillei due to its tuft of coxal setae (lacking in P. berentiensis and P. fertei) but differs from this species by the location of this tuft. As P. fertei and P. berentiensis, there is no spermathecal common duct in P. vaomalalae n. sp.
