Nomada rufa Rossi, 1790

Species originally described from Italy by Rossi (1790). It was considered as a valid species by Balzan et al. (2016). We here consider the name Nomada rufa a nomen dubium; while it likely has priority on other names currently in use, it cannot be correctly attributed to any taxon as the type series is lost and the original description is ambiguous. Material under this name should be revised, and the taxon is for now excluded from the European checklist.
