The first of the only specimens of this species ever found was collected on the 29th of June in 1909 at 3600m elevation at a location Kozhanchikov calls the Map Pass in the Pamir Mountains. According to Trofimova the label on the specimen is spelled slightly differently and that it refers to the Mats River in the Wakhan Range in southern Gorno-Badakhshan in eastern Tajikistan.
