Mydas xanthopterus is a species of mydas fly in the family Mydidae. It occurs in North America, specifically in Mexico and the United States. The species is notable for its resemblance to red-winged Pepsis spider wasps, suggesting possible Batesian mimicry. It occurs in sympatry with Pepsis grossa, a large spider wasp species.
