Chlamydopsis

There are more than seventy species in this myrmecophilous genus of Histeridae.

Species of Chlamydopsis are difficult to define as a group. All species have some kind of trichome on the front corner of each elytron, and a few have additional trichomes on the sides of the pronotum. In contrast to a large number of genera in the subfamily, the scutellum in species of Chlamydopsis is fully exposed, though this is obviously a plesiomorphic character. Most species have the pronotum at least margined laterally, and in most species it is clearly elevated, on both the sides and the front, making the pronotum appear depressed. Essentially all species have strongly dimorphic antennal clubs, with that of the male appearing very elongate, usually longer than all the other segments (including the large scape) combined.
