Diagnosis. The Nomada roberjeotiana species-group is characterized by having (1) setae of subgenital brush long, often recurved apically, or very short and simple; (2) median process of S8 dorsoventrally compressed, short and broad, apex broadly rounded; (3) outer ridge on penis valve angulate or carinate; 4) vestiture of gonostylus sparse and simple, some setae more than half as long as gonostylus, uniformly distributed around gonostylus; as well as by (5) the lack of spinose setae on outer surface of hind tibia in female. For detailed diagnostic characters of this species-group see Snelling (1986) and Alexander (1994).
