The southward range of Cercopeus now extends to northern Florida with the description of komareki O'Brien, new species. Males are described for this bisexual species in a usually parthenogenetic group. C. komareki is separated by a series of diagnostic characters from related or similar species, e.g. clispus Sleeper, strigicollis Sleeper, bolli Burke, and chrysorrhoeus (Say). Illustrations of the female 8th sternite and the male phallus and endophallus of komareki are included. Also figured are the foretibia of the above named species.
