          Abstract

          An inventory of Phlebotomine sandflies was carried out in the Ankarana tsingy located in far northern Madagascar. A total of 723 sandflies were used for morphological, morphometric, and molecular studies (sequencing of partial cytochrome B (mtDNA) and partial 28S (rDNA)). Nine species were identified: Phlebotomus fertei, Sergentomyia anka, Se. sclerosiphon, Se. goodmani, two species of the genus Grassomyia, as well as three new species described herein: Se. volfi n. sp., Se. kaltenbachi n. sp., and Se. ozbeli n. sp. The recognition of these new species is strongly supported by molecular analyses. The first two of the new species could not be classified into any existing subgenus, therefore we proposed two new subgenera ( Ranavalonomyia subg. nov., and Riouxomyia subg. nov.), with combinations as: Sergentomyia (Ranavalonomyia) volfi and Sergentomyia (Riouxomyia) kaltenbachi. Our study reveals important molecular variability in Se. anka, with the recognition of a population whose taxonomic status remains below that of species. Our research confirms the need to further study the specific diversity of Malagasy sandflies, which until the start of this millennium remained mostly unknown.

          Un inventaire des Phlébotomes a été réalisé dans les tsingy d’Ankarana à l’extrême nord de Madagascar. Au total, 723 phlébotomes ont servi à des études morphologique, morphométrique et moléculaire (séquençage d’une partie du cytochrome B (ADNmt) et d’une partie de l’ADNr 28S). Neuf espèces ont été identifiées : Phlebotomus fertei, Sergentomyia anka, Se. sclerosiphon, Se. goodmani, deux espèces du genre Grassomyia, ainsi que trois espèces nouvelles décrites dans ce travail : Se. volfi n. sp., Se. kaltenbachi n. sp., and Se. ozbeli n. sp. L’individualisation de chacune de ces espèces nouvelles est robustement soutenue par les analyses moléculaires. Les deux premières de ces espèces nouvelles ne pouvaient pas être classées dans un sous-genre existant et nous avons proposé pour elles deux sous-genres nouveaux : Ranavalonomyia subg. nov., et Riouxomyia subg. nov, avec les combinaisons Sergentomyia (Ranavalonomyia) volfi et Sergentomyia (Riouxomyia) kaltenbachi.Notre étude révèle une variabilité moléculaire marquée chez Se. anka avec l’individualisation d’une population dont le statut taxinomique demeure populationnel. Nos travaux confirment la nécessité de poursuivre l’étude de la biodiversité des Phlébotomes qui est restée méconnue dans ce pays jusqu’au début de ce millénaire.

          MEGA7: Molecular Evolutionary Genetics Analysis Version 7.0 for Bigger Datasets.

          We present the latest version of the Molecular Evolutionary Genetics Analysis (Mega) software, which contains many sophisticated methods and tools for phylogenomics and phylomedicine. In this major upgrade, Mega has been optimized for use on 64-bit computing systems for analyzing larger datasets. Researchers can now explore and analyze tens of thousands of sequences in Mega The new version also provides an advanced wizard for building timetrees and includes a new functionality to automatically predict gene duplication events in gene family trees. The 64-bit Mega is made available in two interfaces: graphical and command line. The graphical user interface (GUI) is a native Microsoft Windows application that can also be used on Mac OS X. The command line Mega is available as native applications for Windows, Linux, and Mac OS X. They are intended for use in high-throughput and scripted analysis. Both versions are available from www.megasoftware.net free of charge.
