Remarks Gusenleitner & Schwarz (2002) did not confidently place A. arima into a subgenus, whereas Tadauchi & Matsumura (2007) placed it in the subgenus Ptilandrena Robertson, 1902 . Inspection of the type along with additional material from Nepal suggests that A. arima is associated with the subgenus Euandrena due to the simple scopal hairs, pronotum rounded and without a humeral angle, facial foveae weakly dropshaped, weakly sculptured terga, and lack of any other distinctive characters. The use of the subgenus Ptilandrena by Tadauchi & Matsumura indicates that they drew essentially the same conclusions, as Ptilandrena and Euandrena are sister subgenera, but following the revision of Pisanty et al. (2022b) , the use of Ptilandrena is restricted to North America. A specimen of the undescribed male was found in the OÖLM collection, but unfortunately it is stylopised and does not represent a typical individual, so it is not described here. A genetic analysis is required to confirm the phylogenetic position of A. arima , though it appears likely to fall in the derived group of subgenera around or close to Euandrena . Distribution India ( Himachal Pradesh , Uttarakhand ), Nepal *.
