The abdomen is deeply and nearly entirely excavate, the sides 

 are straight, strongly carinate; this carina is flattened, its outer 

 and inner margins are nearly parallel; the strong hook of the 

 dilatated intermediate tibiae, the short and nearly regularly 

 conical antenna? lead at once to the identification of this species.
