[Phlebotomine sandflies from Madagascar (Diptera: Psychodidae). V--description of Sergentomyia majungaensis n. sp]

Sergentomyia majungaensis, a new species of Phlebotomine sandfly, is described from Madagascar. The female is characterised by an unusual antennal formula (1/IV-V to VII; 2/VI to VIII-XV) and smooth and narrow spermathecae, with a common duct, whose shape is intermediate between Sergentomyia and Parrotomyia subgenera. The male has the same antennal formula than Grassomyia (1/IV-XV) but no hairs on the mesanepistern and a longer third antennal segment.
