Very little is known about the biology of Australian Nerthra species.

Entire body covered with short, broadly clavate bristles, bristles pale and especially dense on pronotum and on the elevations of the head. Received Oct 14; Accepted Apr It is divided into two subfamilies, Gelastocorinae and Nerthrinae.
