Gehringia includes only one carabid species, Gehringia olympica, discovered in 1927 by Philip Darlington (Darlington, 1933). Members of this species are minute, about 1.6-1.7 mm long, and live among gravel and coarse sand on the shores of mountain streams in western North America.

Small size (1.6 to 1.7 mm.) is the easiest character observed . Black or very dark piceous, antennae and legs slightly paler, rufescent. Antennae short, pubescent, except on basal segment. Entire upper surface with scattered setigerous punctures. Prothorax cordate. Elytra with deep sutural (and often faintlysuggested second and third) stria, otherwise with the sparse, setigerous punctures arranged in irregular longitudinal rows; apex truncate, exposing the last tergite. Length 1.6 to 1.7 mm.

This species is found in northwestern United States and western Canada, including the north. In Alberta this species has been collected only in the extreme south west corner.
