Ectobius

Ectobius is a genus of non-cosmopolitan cockroaches once thought native to the Old World and described by James Francis Stephens in 1835, belonging to the family Ectobiidae, subfamily Ectobiinae. The discovery of 4 ectobius cockroaches in Colorado dating to 49 million years ago suggests the genus actually originated in North America. This genus has been subject to a number of revisions.
