Andrena nimigracilis Zabinski, new species, is described from a single male specimen from the state of Michoacán in México. It can be distinguished from males of all other species of North American Andrena by the following combination of characters: metasoma extremely narrow, humeral angle extremely weak, propodeum declivitous, genal area small, compound eye wide compared to its length, pretarsal claws with tooth, vertex ≤1.5x lateral ocellar diameter, and wings hyaline. Due to this unique morphology, this species currently cannot be placed into any Andrena subgenus, therefore placed as subgenus incertae sedis.
