Acropteroxys trifasciata

Acropteroxys is a small American genus in the pleasing fungus beetle family (Erotylidae). They belong to the lizard beetle tribe Languriini of subfamily Languriinae; formerly, their subfamily was considered a distinct family, and their tribe upranked to subfamily status, whereas some recent authors prefer to merge Languriinae into subfamily Erotylinae. This genus occurs in North America east of the Rocky Mountains, as well as Central America. Of the handful of species, one ranges as far north as Canada, but most inhabit Neotropical regions.

This genus is presumed to be most closely related to Langurites.
