(

Remarks.
The characters of right surstylus of the new species can be easily distinguished from the Palearctic and Oriental species. It is a little similar to
C. slayi
Disney, 2010
, from Nearctic Region, and
C. megalodus
Schmitz, 1927
and
C. seticerca
Borgmeier, 1969
from Neotropical Region in terms of the characters of right surstylus. The new species is distinguished from them by greater number of inner teeth on left and right surstyli and elliptical left surstylus.
