Antennae reach middle of elytra, proportions of segments are as 8-4-5-7-8-8-9-9-9-9-9, pre-apical segments not thickened, segment 9 about 2.5 times as long as wide on apex. Prothorax 1.6 times as wide as long, broadest in middle, surface shining, strongly punctate, with impunctate area in middle of basal margin. Elytra 1.3 times as long as wide, almost parallelsided with rounded subacute apices, surface very strongly and densely punctate, with a few rows on apices near suture. Propleurae smooth and shining. Abdomen without modifications, apical sternite with straight hind margin, not serrate on sides. Groove of pygidium not ridged on bottom. All femora not toothed, tibiae not modified. Segment 1 of fore and mid tarsi distinctly widened, feebly transverse.

DIAGNOSIS. The new species belongs to group 3 [
Medvedev, 2003
], and seems to be near
C. vietnamicus
Kimoto et Gressitt, 1982
from South
Vietnam
, but differs immediately with much larger size, color and pattern of upperside, strongly punctate prothorax and aedeagus not grooved on underside.
