10. Derancistrus anthracinus (Gahan, 1890) ( Fig. 2e )

Discussion. This species was originally described from Cuba. According to Galileo and Martins (1993b), Lameere (1909) examined the holotype and mentioned mistakenly that this species was Hispaniolan. However, Russo (1930) apparently did collect at least one specimen from the Dominican Republic, saying his material was determined or confirmed by W. S. Fisher. He did not include specific locality data in his publication, however, and his specimen(s) have not been located or their determination verified. This record must be considered with skepticism as no specimens have been seen from any institution or collected by any expedition to Hispaniola since the 1980s.

This species is recognized by its glabrous, dark integument that is black with an azureus tinge; the pronotum with a moderate lateral spine just behind the middle and a smaller spine just in front of the middle; the narrow but distinctly explanate elytral margins; the dense punctures over the elytral surface, forming a semi-rugose surface sculpture at the basal third; and the pronounced prosternal process

that is notched apically and weakly projecting ventrally at the base.

Hispaniolan Localities. D O M I N I C A N REPUBLIC: no specific localities; specimen(s) not verified.
