The male of this species has no constriction of the abdomen 
and the thin chitinous plate at the anterior end of the abdomen 
is much shorter in proportion than in the other two species. 
The female has the same markings on the abdomen and lacks 
the chitinized plate at the anterior end. The epigynum is simi- 
lar to that of C. flavipes Cambr. but the openings are widely 
separated.
