The Steropinae is a little group of midsized beetles. Two recent genera and nine species are known; a single fossil record of Steropes is known from Baltic amber. The general distribution is holarctic, but a single species is known also from the Oriental region. Members of Steropinae are mostly assiciated with arid to semiarid biotopes. The newest species account was published by Telnov (2006). The newest species key was presented by Abdullah (1969).
Frontoclypeal suture well developed to almost atrophied and presented by a transverse impression only. Mandible apices variable. Neck broad, about 1/2 to 1/3 of maximum head width. Three terminal antennomeres strongly elongate in male, significantly longer than previous antennomeres.
Pronotum flattened dorsally, rounded to slightly elongate, anterior rim narrow. Anterior angles not produced. Basal sulcus complete. Dorsal surface densely and evenly pubescent (genus Steropes) or almost without hairs (genus Anisotria). Procoxal cavities open internally and externally.
Elytra flattened dorsally, densely and largely punctured (genus Anisotria) or densely and very finely punctured and covered by dense pubscence (genus Steropes). In males of Steropes elytra are with a large oval inpubescent posthumeral spot. Metacoxae narrowly separated by acute intercoxal projection. Metacoxae nearly contiguous. Hind wings with both radial and anal cells present.
Legs long and with distinct paired tibial spurs.
Abdomen with 5 ventrites. Aedeagus with phallobase and parameres separate. Penis free. Sternite IX v-shaped.

The Steropinae are well-connected with open arid to semiarid habitats (including mountains). Only one species is known from rainforest habitats. These beetles are active diurnally and can often be observed on various vegetation or just running on the ground.
