Bulenides aridus Kleine, 1926b: 152 .
Type material. Male, holotype. [Malaysia] Penang, G. E. Bryant, x. 1913 (without further data) (BMNH).
Remark. Pronotum of C. aridus has well apparent frontal ridges in the pronotum and only lateral ridges are absent.

The pronotum is flat, without characteristically elevated lateral parts of pronotum and lateral margins are parallel-sided in contrast to both species groups.
