The Lechytiidae were first recognized as a tribe of the Chthoniinae by Chamberlin (1929) and were elevated to family level by Harvey (1992). They were segregated from the Chthoniidae and Tridenchthoniidae by a small suite of characters.
The family Lechytiidae includes only a single genus, Lechytia, which contains 24 species.
Lechytiids occur in most regions of the world, particularly in tropical and sub-tropical zones. They occur under or amongst the bark of trees, or under rocks.
