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

Background: 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. methods: 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). results: 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. conclusions: the description of a new species in thailand is of importance in view of the existence of autochthonous leishmaniases. © 2016 polseela et al.
