Classification The Ropalomeridae consist of eight genera and 26 valid species restricted to tropical and subtropical America. Only Ropalomeridae belong to the superfamily Sciomyzoidea, one species has been found north of Mexico, Rhytidops a group including Coelopidae, Dryomyzidae, Helosciomyzi floridensis, and three species occur as far sOllth as northern dae, Sciomyzidae, and Sepsidae. The morphological evidence Argentina. Most species occur in the central portion ofSoulh from adults suggest that Ropalomeridae are the sister group America (Steyskal, 1967, 1987).
