Holcaspis brevicula

Holcaspis brevicula, the Eyrewell ground beetle, is a species of carabid beetle native to New Zealand, one of a number of small black flightless beetles in the genus Holcaspis that inhabit the dry eastern lowlands of the South Island. H. brevicula is very rare—only ten specimens have ever been collected—and either critically endangered or extinct: the species was found only in Eyrewell Forest, a single plantation of exotic pine trees now converted into dairy farms.
