Abstract
A new species Oecetis McLachlan, O. psammophila sp. nov., is described from the Sandhills ecoregion of South Carolina. Illustrations of male and female genitalia and wing photographs are provided. Following the classification of Chen (1993), O. psammophila belongs to the O. parva Species-group of the subgenus Pseudosetodes Ulmer. Adult specimens were taken at ultraviolet lights near or immediately adjacent to impounded streams or spring-fed wetlands. The larva remains unknown, but other Nearctic members of the O. parva Species-group inhabit lentic habitats.
