Nomada vegana Cockerell 1903 ( vegana group) (New state record)

County records: Allegan, Cass.

Notes. Some taxonomic problems associated with members of the vegana species group were resolved by Droege et al. (2010). Nomada vegana was not treated in that paper, but Droege et al. (2010) provide useful information for comparison to other members of the group that occur in Michigan, including N. fervida (and its midwestern dark color form N. wisconsinensis Graenicher , previously considered as a distinct species, e.g., by Wolf & Ascher, 2009) and N. tiftonensis (treated as a junior synonym of N. heiligbrodtii Cresson by Mitchell, 1962 and Hurd, 1979, and also considered as a junior synonym of N. texana Cresson in earlier drafts of Ascher & Pickering, 2017).
