St. Domingo: Sharp (1882: 568) ; without precise locality: Blackwelder (1944: 77) , Peck (2005: 44) , Perez-Gelabert (2008: 77) . Diagnosis. See Megna & Epler (2012) . Remark. This species was recorded from Hispaniola by Sharp (1882) from Santo Domingo , and from Jamaica by Schaeffer (1908) . Both records were subsequently repeated by Blackwelder (1944) . However, the latter author was apparently not aware that at the same time, Young (1942) treated Antillean Copelatus of the hydroporoides - group, described several new species from Cuba and Jamaica and restricted the occurrence of C. insolitus to Cuba . Therefore, we consider its presence in Hispaniola as improbable. We were not able to trace any specimens of the hydroporoides -group from the Dominican Republic, but if such exist, they likely represent another, potentially undescribed species. Distribution . Cuba ; occurrence in Jamaica and Hispaniola doubtful.
