This evaniid has a more northern distribution than any other in 

 the Nearctic Region. It occurs in the Eastern United States and 

 as far west as Minnesota and Kansas, commonly in the Upper Austral 

 and the warmer parts of the Transition Zone. This species and 

 Hyptia thoracica occur in Ontario and are the only evaniids recorded 

 from Canada.
