Elaphropus quadrisignatus
A small ground beetle in the family Carabidae, originally described as *Elaphrus quadrisignatus* by Duftschmid in 1812 and later transferred to *Elaphropus*. The species is documented from scattered records across Europe and North Africa, with 24 observations reported on iNaturalist. As a member of the tribe Bembidiini, it belongs to a diverse group of small carabids often associated with moist microhabitats.
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.
