Cryptocephalus irroratus Suffrian 1852: 32.

Diagnosis. This species exhibits characters of the genus Cryptocephalus (hind femora not greatly enlarged in comparison to those of front and middle legs, base of pronotum crenulate rather than being margined by distinct bead, apical abdominal tergite largely exposed beyond elytra, tarsal claws simple). Additionally, the punctures in the basal two-thirds of the elytra are not arranged in rows (except laterally). The elytra are yellow with brown punctures and with two irregular, brown, transverse bands in the posterior half (Fig. 26). Additional brown markings are sometimes also present. This combination of characters is not found in any other chrysomelid species known to occur in the Cayman Islands.
