Abstract. Anapeptaineiui Konow (Tenthredinidac: Sclandriinae) has been known only
by its type species. A. iilbipes Konow. from India and Myanniar Two new species have
beendiscovered from Indiaand aredescribed:Anapeptamenadarjeelingensis,n.sp.,and
A. dhanoiiltiensis, n. sp. A male ofthe genus, that ofA. dhcmoiiltiensis. is described for
the hrst time. Descriptions, illustrations, and a key are provided for identification ofthe
species.
