According to the author, this species is allied to C. punctulata, Brunn., but differs 

 from it in the non-rufous forehead and the very long elytra and hind femora, as well as 

 in the number of spines on the anterior tibiae and in the structure of the anal pieces.

The males of this genus have a long appendage on each side of their last dorsal 

 segment; the infra-genital plate is elongate-trian gular- truncate, bicarinate, the carinae 

 terminating in the apical angles, which bear short styli.
