According to the published itinerary of A. K. Holbek, the collector of the type specimen (Izvestiya Russkago Geograficheskago Obshchestva 51 (1915): 79-85), the collecting date (26.vi.1911) indicates that the type locality is situated between Derbent and Guzar, i.e. in UZ (Surkhandarinsk Prov.), not in Tadzhikistan as hitherto maintained.
The record from Inner Mongolia (Li et al., 2008) is doubtful ( Vinokurov et al., 2018).
