Discovery of a new species of Lonchodryinus from Madagascar (Hymenoptera, Dryinidae)

A new species of pincer wasp, Lonchodryinus ater sp. nov. (Hymenoptera, Dryinidae) is described from Madagascar, Toliara province, Beza Mahafaly Reserve. The new species is close to L. hovanus Olmi, 2004. However, it is different because POL is about twice as long as OL; the mesoscutum is dull, very strongly punctate and sculptured by short irregular longitudinal keels; the paramere has not a mosaic structure on the inner side (in L. hovanus, head with POL less than twice as long as OL; mesoscutum shiny, very strongly punctate, unsculptured among punctures; paramere with mosaic structure on inner side). A new key to the males of the Afrotropical Lonchodryinus is presented.
