Diagnosis.

2.55-2.8 mm (mean = 2.67 mm; n = 5), 3.19-3.50 × as long as wide. This species is distinguished by the elytra attenuate, apex emarginate, elytra deeply excavated between interstriae 3, excavated area unarmed and anterior margin of pronotum without serrations.

Similar species.

C. obtusicornis .

Distribution.

Argentina (Misiones), Brazil (Bahia, Espírito Santo, São Paulo), Colombia (Valle de Cauca), Costa Rica (Cartago, Limón), Ecuador* (Los Ríos, Orellana, Pichincha), French Guiana*, Grenada, Guyana*, Mexico (Oaxaca, Veracruz), Peru (Loreto, Madre de Dios), Saint Lucia, Venezuela (Aragua, Miranda).

Biology.

This species has been recorded from Magifera indica ( Anacardiaceae ), Hevea brasiliensis ( Euphorbiaceae ), Inga ( Fabaceae ), Theobroma cacao ( Malvaceae ), and Cestrum ( Solanaceae ) ( Wood and Bright 1992; Bright and Skidmore 1997; Wood 2007). Wood (1982) reported collecting specimens from dying and recently cut limbs and boles 10-30 cm in diameter and that the gallery comprised a simple entrance tunnel that was expanded by the brood into a small tabular cavity that followed the grain of the wood. The species has also been recorded from a cut hanging liana 4 cm in diameter and by canopy fogging.
