Numerical Taxonomy of Old World Phlebotominae (Diptera: Psychodidae): 1. Considerations of Morphological Characters in the Genus Phlebotomus Rondani & Berté 1840
“…Within the Phlebotominae of the Old World, the genus Sergentomyia França & Parrot, 1920 appears to be a catch fall group, including all the Old World species excluded from all other genera ( Phlebotomus , Idiophlebotomus , Chinius , Spelaeophlebotomus , Grassomyia , Parviden s, Spelaeomyia and Demeillonius ) [24], [25], [32]. Species of the genus Sergentomyia share the following characters: a mesanepisternum without setae, abdominal tergites 2–6 carrying usually all or most recumbent hairs, an usual 1/III–XV antennal formula in the males and 2/III–XV in the females with some exceptions, a cibarium with an armature of teeth and/or denticled more developed in females than in males (beyond exceptions), a single paramere, a style with four terminal spines (or often 2 terminal and 2 subterminal) and an accessory spine.…”
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.

“…However, it was recently found that species from other genera could also play a role in leishmaniases transmission in Theodor, 1948, and (Kasaulius) Lewis, 1982. However, Rispail andLéger (1998a) thought the subgenus (Anaphlebotomus) is artificial, because it includes two lineages. New species from Madagascar belonging to this group were recently described (Depaquit et al 2002, Randrianambinintsoa et al 2013, suggesting this subgenus needs to be revised.…”
“…The renewed interest in the classification of Phlebotominae on morphological characters can contribute to this (Galati 1995, Rispail & Léger 1998a but analyses of molecular data will probably help to resolve both taxonomy and phylogeny less ambiguously than has been possible by morphology alone. We suggest that inclusion of L. derelicta in such analyses would be of particular interest.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
