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).
