Description of the new subgenus Metoporaphodius subgen. n. of the genus Aphodius Helw. (Coleoptera, Scarabaeidae) and of the larva of its type species, A. plustschewskii D. Kosh.

Abstract

The new Irano-Turanian subgenus, Metoporaphodius subgen. n., is erected in Aphodius Helw. for A. plustschewskii D. Kosh. (type species) and A. baghlanicus Frolov. The males of Metoporaphodius subgen. n. are distinguished by the presence of a comb of dense setae on hind tibia and by the parameres with spatulate projections. The 3rd instar larva of A. plustschewskii has 2 rows of large flattened spinules on anal stemite (with 10-12 spinules in a row), and 3 spinules on the lacinial apex.
