Clanis undulosa Moore, 1879 ( Fig. 2D )

Material examined. 1 ♂, Russia, Khabarovsk Kray, Bikin district, 8 km SE Boitsovo village, upper reaches of Shivki River, vicinity of Shivki scientific station of Institute of Water and Ecology Problems FEB RAS, 46°55'06" N, 134°23'04" E, 165 m, mixed coniferous- broad leaved forest, 30.06.2021 (E.S. Koshkin leg.) .

Remarks. This Southeastern and East Asian species was recorded in the territory of the Russian Federation in 1975, when the first specimens were collected in the Khasan district of the Primorsky Kray ( Dubatolov 2021). Later, it naturalized throughout almost the entire southern half of the Primorsky Kray, reaching the Spassk district in the north ( Koshkin et al. 2015). A.V. Korshunov collected a female specimen in Khabarovsk city in late July 2014 ( Koshkin et al. 2015). There have been no other reliable data indicating that the species inhabit Priamurye ever since. A male specimen was collected in the southern Khabarovsk Kray, in the Bikin district, in late June 2021 ( Fig. 1 ). Since only sporadic finds were made in Priamurye (yet, the collected specimens are in excellent condition), we can assume that the species is currently slowly naturalizing in this region. There is a record of one male specimen collected in the northwestern Jewish Autonomous Oblast’ and stored in the Jean Haxaire collection (labelled «Amurland, Maly Khingan Mt., Oblutchie, 48.2 N, 130.767 E, 600 m, 1993-08-01, S. Andreev») ( BOLD Systems 2021, public BIN SOWA537-06). According to S.A. Andreev (pers. comm., August 21, 2021), this label is erroneous, since he has not collected this species in Obluchye town, only in the Khasan district of the Primorsky Kray. Larvae feed on Lespedeza bicolor ( Fabaceae ), which is widespread in the nemoral zone of the Russian Far East ( Zolotuhin & Evdoshenko 2019).
