Holotype (NMNH), examined.

New records.

Diagnosis.

2.1-2.3 mm, 2.6 × as long as wide ( Bright and Torres 2006). This species is distinguished by the elytral apex feebly acuminate, declivital interstriae unarmed along its entire length, and antennal club with three sutures on posterior face.

Similar species.

C. attenuatus , C. katniss , C. sagitticauda , C. sarahconnor , C. sicula , C. yar .

Distribution.

Grenada, Puerto Rico.

Biology.

Unknown.

Remarks.

Wood’s (2007) measurements of three paratypes differ compared to the measurements of Bright and Torres’ original description (2006) and those of Bright (2019). Given the previously noted observations of calibration error in Wood’s measurements, these values are not included here. Bright (2019) reports that this species has only one suture on the posterior face of the club but it has two.
