Diagnosis. In the Cayman Islands, this genus is distinguished from other chrysomelids by the wellformed basal bead of the pronotum, the exposed pygidium, and the front femora that are enlarged in comparison to those of the middle and hind legs. This species differs from the other Cayman Islands species of Pachybrachis   in numerous characters, including the smaller body size (2.0- 2.3 mm, compared to 3.0- 4.2 mm long), the eyes that in either sex are separated by many times the length of the basal antennomere, and the more alutaceous integument.
