excavate, clypeus posteriorly broadly carinate ; pronotum at base a little broader than 
long, centrally longitudinally depressed, anterior margin truncate, posterior margin 
angularly concave, lateral margins obliquely rounded; mesonotum with the disk 
centrally flattened into a broad longitudinal process, the margins of which are a little 
upwardly raised ; tegmina about twice as broad as long, the costal membrane about or 
a little more than four times as broad as radial area, strongly arched at base, strongly 
transversely veined, the tegmina are broader at base than at apex where they are 
roundly obliquely truncate, posterior claval angle broad, the whole venation coarse 
and prominent; wings about as broad as tegmina; posterior tibize with a distinct 
subapical spine. 
This genus belongs to the Division Flatoidesaria, and is allied to the genus Urantis 
Stal, from which it differs in the distinct structure of the head.
