Diagnosis. Shield with anterior margins straight, anterolateral margins oblique forming obtuse angle with anterior margins. Rostrum small, acute, triangular. Ocular peduncles shorter than anterior width of shield. Antennal peduncles with last segment less than 2.5 times as long as broad. Propodi of ambulatory legs with 4 thin light stripes on lateral face, separated by broad dark stripes.

Distribution. Western Atlantic—Virginia, Carolinas, Florida, Gulf of Mexico, Antilles, Venezuela, Suriname and Brazil (from Amapá to Santa Catarina).

Remarks. In the diagnosis, we presented some morphological characters that distinguish C. vittatus from C. sclopetarius , based on Holthuis (1959). Nevertheless, Forest & Saint Laurent (1968) examined specimens of the two aforementioned species and failed to distinguish them based on the characters proposed by Holthuis (1959). Therefore, it is difficult to distinguish the two species based only on morphological characters. Fortunately, the two species maintain the color pattern for a long time when preserved in alcohol.
