Ammostigmus, a New Genus of Digger Wasps of the Subtribe Ammoplanina (Hymenoptera, Crabronidae) from Southwestern India

摘要

A new pemphredonine genus, Ammostigmus (Hymenoptera, Crabronidae), is described from southwestern India. The new genus differs from the other genera of the subtribe Ammoplanina in the quadridentate apical margin of the clypeus, non-bilobed labrum, thepresence of postspiracular carina and omaulus, and the absence of episternal sulcus. Phylogenetically the new genus is most closely related to the genus Protostigmus Turner, 1918.
