Trechini

Trechini is a large tribe of ground beetles in the family Carabidae. There are more than 270 genera and over 2,400 described species in Trechini, found throughout the world.

The ground beetles of this tribe are small, typically less than 5 mm in length and sometimes 1 mm or less. They occur in a wide variety of habitats on every continent except Antarctica. Though the extinct genus Antarctotrechus indicates that they were formerly present on that continent.
