Diagnosis.

Like Caribbomerusribbomerus attenuatus (Chevrolat) and Caribbomerus similis (Fisher), Caribbomerus asperatus has a very diagnostic rugulose pronotum that lacks calli and pubescence. It is recognized by a combination of features that include the matte finish on the elytra, micropunctation between elytral punctures, relatively uniform reddish-brown coloration above, distinctly elevated antennal tubercles, and elytral apices not distinctly impunctate.

Discussion.

This is the most common species of Caribbomerus in Hispaniola. It was originally described based on specimens from Haiti, and has not been previously recorded from the Dominican Republic ( Fisher 1932, Monné and Bezark 2010). With numerous collection records listed below, this species is now documented for the Dominican Republic (new country record).
