Diagnosis.

1.8-2.0 mm (mean = 1.86 mm; n = 5), 3.0-3.33 × as long as wide. This species is distinguished by the elytral apex attenuate and strongly emarginate, declivity convex, declivital interstriae 2 denticulate, elytral apex with interstriae 3 and 9 joining, forming a smooth continuous carina that continues submarginally to apex, apex produced, declivital interstriae 3 denticles much larger than those of interstriae 1, and interstriae setae with short erect bristle-like setae that are shorter than interstrial width.

Similar species.

C. leporinus , C. gracilens .

Distribution.

Brazil ( Espírito Santo), Ecuador* (Orellana), Peru* (Madre de Dios).

Biology.

Specimens were collected by canopy fogging as well from the wood of an unidentified branch.

Remarks.

Wood (2007) incorrectly reported the holotype’s location as MZUSP; the holotype is in MEFEIS.
