Diagnosis: Male 3.0–4.0 mm long; derm piceous; rostrum continuous with frons, longer than half body length, longer in female, but not longer than body; pronotum with ventroanterior macula with lateral arms that reach to midpoint of eye and not visible in dorsal view, basolateral macula with median margin reaching elytral interval 5 meeting basal fascia of elytra forming V shaped fascia with piceous scutellum in middle; elytra with basal fascia from intervals 1–5, submedian fascia on intervals 1–9, with apical vittae along crosshatch setae in apical 0.25, all scales clavate, cretaceous, tightly packed; metafemur reaches or barely exceeds apex of elytra; venter clothed with cretaceous scales.

Differential diagnosis: This species closely resembles C. analis , but is smaller in size. The pronotal basolateral macula reaches elytral interval 5 whereas in C. analis it reaches interval 4. The metafemur barely exceeds the apex of the elytra, ventrite 5 lacks 2 tufts of apical setae, and the mesofemur has a basal fringe of long hair wanting.

Distribution: This species is found only on Malaysian Borneo: Sarawak, Quop and Puak.
