Trechus satanicus

Trechus satanicus is a species of ground beetle in the subfamily Trechinae, described by Barr in 1962. It belongs to the genus Trechus, a large and diverse group of small carabid beetles distributed across the Northern Hemisphere. The species epithet "satanicus" refers to its association with subterranean or cave-like habitats, from which the name derives. Like other members of Trechus, it is likely adapted to moist, dark microhabitats.
