Andrena (Micrandrena) nanaeformis Noskiewicz, 1925

Remarks. Listed by Comba (2019) [species 139], citing Comba & Comba (2001) who recorded it from the Italian Alps. This is ecologically implausible, as A. nanaeformis is a species of grassy Eurasian steppe, found from central Germany (extinct) to Kazakhstan ( Gusenleitner & Schwarz 2002; Westrich et al. 2011). We have examined no material of A. nanaeformis from the mountains of Central Europe. Although the alpine valleys of northern Italy and southern Switzerland can host (at least historically) certain steppe species such as A. incisa Eversmann, 1852 , these are typically species of dry steppe (e.g. present also in Iberia or Turkey) which do not fit the distributional pattern of A. nanaeformis , and the species is excluded from the Italian list until it can be positively confirmed through specimens or genetic data. The material reported by Comba & Comba (2001) is not currently available to us for study.
