Taxonomy: The lectotype designated by Schedl (1979) is in NHMW.

The species is related to C. micrographus and C. simplex , but distinguished by the matt elytral declivity, and other characters given in the key.

Distribution: West Malaysia. The species is newly recorded here from East Malaysia (Sabah, Sarawak),
