“General: Body 1.75 to 1.80 times as long as wide; dorsal surface shining, lacking pubescence; most of ventral surface with short, sparse, whitish pubescence. Head: Dull light orange, antennal insertions darker orange, front evenly, moderately, densely punctate; vertex shallowly grooved or depressed; clypeus sharply delimited, distinctly broadest apically. Antennae nearly as long as body in male, or nearly two-thirds as long as body in female; dull light orange. Pronotum: Dull light orange, with generally distinct, fine, darker speckling which is absent basally at center, anteriorly on each side, and at apex. Punctation dual, smaller punctures minute and sparse, larger punctures small to very small, not coarse. Elytra: Dull light orange; each elytron with distinct to vague indications of two dull reddish, transverse, undulate bands; humerus dull reddish; punctures dark reddish. Each elytron with nine even and distinct rows of close, fairly large punctures; rows seven and eight behind humerus nearly always interrupted and joining each other; punctures distinct to apex, somewhat smaller apically; inner and outer rows at apex distinct and clearly meeting. Ventral surface: Ventral surface and appendages dull light orange, apices of femora light; metasternum reddish. Anterior margin of metasternum in male broadly produced ventrally into a V-shaped pointed lobe; anterior margin in female broadly produced ventrally into a blunt lobe. Fifth abdominal segment in female at center with a deep oval depression, or fifth segment feebly depressed in male. Length: 3.5 to 4.8 mm” (White, 1968: 95).
“The species is similar to the description of C. obscuripennis Jacoby (1880, p. 54) described from Guatemala. In vapidus, the antennae are orange throughout; those of obscuripennis are described as having the terminal segments black. The name vapidus (meaning dull) refers to the body color of this species” (White, 1968).
