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 .
