Remarks. This species, originally described in Diplomaragna ( Shear 1990) , has since been transferred to the restored Ancestreuma ( Mikhaljova 2000) . Hitherto the species is known from Russia (Siberia: Krasnoyarsk Province, Irkutsk area, Republic of Tyva) and Mongolia (Khubsugul Lake, River Ongolich). The record in Evenkia ( Mikhaljova 1993) actually refers to Ancestreuma ryvkini ( Shear, 1990) . This conclusion was confirmed by the reexamination of a sample from the locality being kept at IBSS (1 male, Russia, Krasnoyarsk Province, Evenkia, 140 km upstream of Velmo River, 10.VIII.1990, leg. A.B. Ryvkin). The erroneous information about the record of this species in Evenkia ( Mikhaljova 1993) was accepted in subsequent publications ( Mikhaljova 2000; 2002; 2004).
