In ventral view, aedeagus parallel-sided. Apex of aedeagus in ventral view narrowing abruptly. Ventral surface of apical fourth of aedeagus deeply concave, ventral longitudinal groove of aedeagus well developed, deep, narrowed near basal opening. Apical denticle of aedeagus absent or extremely weak. Minute transverse wrinkles on ventral side of aedeagus well developed. Aedeagus in lateral view evenly and strongly curved.

Remarks: Punctation of dorsum in C. malayana and C. concinnipennis are extremely alike. However, they can be distinguished from each other by the structure of aedeagus. Moreover, in C. concinnipennis , punctures on dorsum are large and extremely closely placed, but in C. birmanica , punctures are smaller and the interspaces are wider.

This species is also close to C. bretinghami , from which it can be distinguished by the closely paced elytral punctures.
