Teretriopsis

There is a single species in this myrmecophilous genus of Histeridae.

Because this genus is known from a single species, it is impossible to confidently determine characters by which it will consistently differ from other genera. It shares with Ceratohister the (apomorphic) lack of humeral trichomes, but differs from all known Ceratohister quite radically in body shape, mainly in its subcylindrical habitus. Its lack of pronotal processes also separates it from most Ceratohister (except for C. leai, which occurs in Sarawak, Bornean Malaysia).

The single species of this genus has been collected only by flight interception traps.
