Stylops pascarellai n. sp. is described from five female specimens collected in their host, Andrena primulifrons. This host is in the subgenus Andrena (Micrandrena) and other strepsipterans hosted by members of this subgenus in the United States are reviewed. One of these species, Stylops bruneri is found to include four other previously described species. Two of these species, Stylops hartfordensis n. stat. and Stylops nasoni n. stat. are returned to synonymy with S. bruneri. Stylops duboisi and Stylops neonanae are maintained as valid species.
