Diagnosis.
Length:
4.20–5.50 mm

congeners by its characteristic, cordate or heart shaped body outline (
Fig. 25a, b
) that is distinctly narrowed in the apical one-third, uniform black coloration and elytra with finely punctate disc and coarsely punctate lateral margins.
Male
genitalia (

It appears to be a rare species apparently endemic to the eastern Himalayan region and is not commonly represented in collections.

gave a brief account of
C. braeti
in his work on the
