NOTES. Our data confirm the presence in the Baikal region only O. ussurica (= O. koreana ; the synonymy is established by Beljaev, 2016). The easternmost actual locality for O.

sambucaria is Cheryomushki village in Krasnoyarsky krai (Zolotuhin, 2017). Due to the difficulty for discrimination of species from O. sambucaria – group and potential overlapping of the ranges of O. sambucaria and O. ussurica in the Southern Siberia, a key to these species is given below.

1. Forewing pointed and distinctly falcate to apex. Straight line drawn along outer margin of hind-wing from its anterior angle to base of tail (wing projection at M3 vein) runs basad of anterior spot on the tail base; longitudinal axes of anterior and posterior spots in base of tail form almost a right angle ( Fig. 7 ). In male genitalia distal process of uncus relatively thick, basal half of calcar (process of juxta) straight; apex of calcar rounded- blunted, basal process of aedeagus bent ventrally, cornuti on vesica moderately thin, almost as long as width of aedeagus in middle part. In female genitalia proximal sclerotized portion of corpus bursae is straight ..……………………………..………. O. sambucaria

– Forewing less pointed and not falcate, outer margin of the wing almost straight. Straight line drawn along outer margin of hind-wing from its anterior angle to base of tail runs through anterior spot on the tail base; longitudinal axes of anterior and posterior spots in base of tail form a wide obtuse angle ( Fig. 8 ). In male genitalia distal process of uncus thin, basal half of calcar smoothly curved; apex of calcar tapered-pointed (beak-shaped), basal process of aedeagus not bent ventrally, cornuti on vesica very thin, much longer than aedeagus width in middle part ( Figs 9–11 ). In female genitalia proximal sclerotized part of corpus bursae is curved …………………………………….……….... O. ussurica reticulata Sterneck, 1928 , female; 3 – Abraxas karafutonis Matsumura, 1925 , female; 4 –
