(Figs. 1C, 1E)
Material examined. 3♂, Russia, Khabarovsk region, Bikin district, 8 km SE of Boitsovo village, upper reaches of Shivki river, vicinity of “Shivki” scientific station belonging to the Institute of Water and Ecology Problems of the Far Eastern Branch of the Russian Academy of Sciences, 46°55'06" N, 134°23'04" E, 165 m, mixed coniferous-broad leaved forest, 8 May 2021 (E. S. Koshkin leg.).
Distribution. Russia: Khabarovsk region (first records), Primorsky region; Korea (Schintlmeister 2008).
Remarks. V. Dubatolov raised the question of the boundary between the ranges of closely related species O. brinikhi Dubatolov, 2006 and O. patricia, inhabiting the south of the Russian Far East (Dubatolov, Dolgikh 2007; Dubatolov 2011; 2019). He points to the bilobed apex of the uncus in the male genitalia of O. patricia as one of the important features distinguishing it from O. brinikhi (Fig. 1E). The apex of the uncus in O. brinikhi is not bilobed (Fig. 1F). The forewing of O. patricia is brownish-gray with whitish suffusion; a dark medial field bounded by whitish antemedial and postmedial zigzag lines are clearly visible; there is a noticeable whitish spot in the tornal angle; discal spot is more or less distinct (Kobayashi et al. 2006) (Fig. 1C). O. brinikhi forewing’s pattern is less contrasting, and many details are often diffuse (Fig. 1D). Schintlmeister (2008) considers O. brinikhi a subspecies of O. patricia.
O. brinikhi is widespread in Eastern Siberia and the Amur basin, from the East Sayan mountains in the west to the coast of the Tatar strait in the east and from Central Yakutia (Sakha Republic) in the north to Khabarovsk in the south (Kobayashi et al. 2006; Dubatolov, Dolgikh 2007; Dubatolov 2011; 2019). The range of O. patricia is limited to the southern part of Primorsky region and Korea (Schintlmeister 2008; Chistyakov, Dubatolov 2016). However, Schintlmeister marked a locality in Sovetsko-Gavansky district of the Khabarovsk region on an O. patricia range map included in his book (2008). This is most likely a mistake. V. Dubatolov writes that he studied extensive material on Odontosia from the coast of the Tatar strait and other localities within the Khabarovsk region (Dubatolov, Dolgikh 2007; Dubatolov 2011; 2019). None of the males had a bilobed uncus. It was concluded that there is no reliable data on O. patricia presence in the Khabarovsk region, and all similar specimens belong to O. brinikhi.
Prior to our research, there was no data about Odontosia species from the southernmost part of Khabarovsk region (Bikin district). Males collected in May 2021 in the upper reaches of Shivki river belong to O. patricia both in their appearance and in the structure of male genitalia (bilobed uncus) (Figs. 1C, 1E). Specimens similar to O. brinikhi were not found. Interestingly, the only O. brinikhi was recorded 200 km to the north, close to Khabarovsk (Dubatolov, Dolgikh 2007). Probably, the boundary between the ranges of these closely related taxa is located in the lower reaches of the Ussuri river in the southwest of the Khabarovsk region. The finds of O. patricia from the Bikin district are the first reliable evidence of its residence in the Khabarovsk region.
