New genus Odontacrossus for Aphodius (Acrossus) obenbergeri, A. (A.) pseudoobenbergeri and A. (Paulianellus) trisuliensis (Coleoptera: Scarabaeidae: Aphodiinae)

Abstract

A new genus, Odontacrossus, is diagnosed and three new combinations are proposed, i.e.: Aphodius (Acrossus) obenbergeri Balthasar, 1932, comb. nov., Aphodius (Acrossus) pseudoobenbergeri Červenka, 1995, comb. nov. and Aphodius (Paulianellus) trisuliensis Stebnicka, 1986, comb. nov. The primary characteristics of Odontacrossus gen. nov. are a triangular process protruding from the middle of the clypeal margin of males, an anterior margin of the epipharynx distinctly inwardly sinuate at middle and an obsolete epitorma and corypha.

A summary of the distribution of this new genus, which is restricted to the Himalaya and SE parts of the Tibetan Plateau, is presented and a key for identifying the species compiled.
