Notaris (Erirhinus) aethiops (Paykull, 1792) ( Figs. 1A , 2A , 3 )

General distribution. Boreal zone of Eurasia and North America.

Distribution in Asian Russia. Western Siberia (Yamalo-Nenets Autonomous Okrug, Khanty-Mansi Autonomous Okrug, Tyumen Oblast, Tomsk Oblast, Novosibirsk Oblast, Kemerovo Oblast, Altai Krai, Altai Republic, Republic of Khakassia: 40 km WNW of Tashtyp; Karasibo River – new record; Krasnoyarsk Krai, Tyva Republic), Eastern Siberia (Irkutsk Oblast, Zabaikalskii Krai, Sakha (Yakutia) Republic), Far East (? Chukotka Autonomous Okrug, Kamchatka Oblast, Magadan Oblast,? Amur Oblast,? Khabarovsk Krai,? Primorsky Krai).

Remarks. This species is common in the boreal regions of Western Siberia and in the tundra-steppes of South-eastern Altai. Several localities are known in Yakutia ( Averensky 1999) and in the North-East of Russia ( Korotyaev 1980). This species is recorded for the Amur Oblast, Khabarovsk and Primorsky Krais ( Egorov et al. 1996), but the finds in these regions were absent in the earlier works of A.B. Egorov (1976, 1977, 1981). This species is recorded for Chukotka ( Anderson, 1997), but the data on the finding from this region in the works of Korotyaev (1980), and Khruleva and Korotyaev (2012) is absent also. It was distributed in the Pleistocene of Western Siberia (including the southeast) ( Zinovyev 2011; Legalov et al. 2016; Zinovyev et al. 2016; Gurina et al. 2018, 2019) and the North-East of Russia (including Chukotka) ( Kiselev and Nazarov 2009; Kuzmina and Matthews 2012).
