Taxonomic Notes: Nomada vegana Cockerell is the type species for Micronomada Cockerell (Cockerell 1903: 610).

Cockerell (1903: 610) listed two locations for the syntype series of N. modesta var. vegana, New Mexico (Las Vegas) and Colorado (Colorado Springs), and no clear designation was made. However, Cockerell (1912: 235) indicated Las Vegas as the type location, so that work is considered a desgination of the lectotype.

Nomada vegana Cockerell was first considered a distinct species by Cockerell (1905: 76) who also recognized the male, indicating that they were similar to N. modesta Cresson, but smaller. Swenk (1913: 27) suspected that N. modesta vegana was conspecific with N. modesta, and Rodeck (1951: 1203) and Hurd (1979: 2112) later considered both Cockerell’s taxa as synonyms of N. modesta. Since N. modesta Cresson is a preoccupied name (see Alexander and Schwarz 1994: 242), N. vegana is the valid name for this taxon.
