Readily distinguishable by the male sexual characters, strongly asperate sculpture and well marked coloration.

The following nine species can be recognized by individual peculiarities of sculpture, coloration or male sexual characters; they all belong to typical Atheta, but in no case is the sixth tergite clearly crenulate at apex in the male, so far as known.

I have described this species from the female because of its very distinct abdominal sculpture, distinguishing it from any other species of true Atheta here made known; also because of its large size and other striking characters. The male is unknown.
