Diagnosis. See Megna & Epler (2012).

Variability. In specimens from the Dominican Republic, strioles on the pronotum are less deeply impressed than in those from Cuba. Specimens from Cuba and from the Dominican Republic tend to display a more contrasted dorsal colour pattern than those from Guadeloupe (testaceous areas along pronotum lateral margins, elytral base, lateral margins and towards elytral apex, more extended and better delimited), with some variability in all localities.

Collection circumstances. Copelatus posticatus   is the most frequently collected species of the genus in the Dominican Republic. It was found in lentic (permanent and temporary) habitats, where it was predominantly associated with turbid waters with muddy bottom.

Distribution. Widespread Neotropical species, from Mexico to Brazil. In the Antilles, recorded from Barbados, Cuba, Dominica, Dominican Republic, Grenada, Guadeloupe, Montserrat, Puerto Rico, Saint Lucia, Saint Vincent, and Tobago.
