Nomada armatella Cockerell, 1903 View in CoL (ruficornis group)

Yellow-backed Nomad

Notes: The status of this species is poorly understood because only the male is described by Mitchell (1960). Due to variation in the color of the scutellum, atypical males of N. armatella and N. cressonii can potentially be confused by those relying on Mitchell’s keys. Pronotal color also seems to vary, and further documentation of structural characters of both sexes is needed. Placement of N. armatella sister to N. depressa rather than close to N. cressonii by Odonaka et al. (2022) suggests that their concept of this species may differ from ours (see above).
