Tachyina
Tachyina is a subtribe of small ground beetles (Carabidae: Trechinae: Bembidiini) established by Motschulsky in 1862. Members include diminutive species typically measuring 2–3 mm in body length. The subtribe contains genera such as Tachyura, characterized by distinctive male genitalic morphology and specific puncture patterns on the elytra. Taxonomic revisions continue to clarify species boundaries and the availability of historical infrasubspecific names.
