Acosmeryx naga (Moore, [1858]) ( Fig. 2E )

Material examined. 2 ♂, Russia, Amur Oblast’, Blagoveshchensk district, Mokhovaya Pad’ village , 50°23' N, 127°37' E, 200 m, oak- deciduous forest, 3.07.2021 ( V. G. Bezborodov leg.) .

Remarks. The species was first recorded in the territory of the Russia Federation in 2002; the first finds were made in the Khasan and Ussuriysk districts of the Primorsky Kray ( Beljaev 2003). Later, A. naga widely extended its range and naturalized in the southern Primorsky Kray. There are data on finds of species in the Spassk, Lazovsky and Shkotovsky districts ( Tshistjakov 2009; Koshkin & Bezborodov 2013; Pittaway & Kitching 2021). The two male specimens collected in the vicinity of Blagoveshchensk is the first record of A. naga in the Amur Oblast’ and Priamurye in general ( Fig. 1 ). It is not clear yet whether these specimens are migratory or naturalization of species has begun in the Middle Priamurye. Larvae in the Primorsky Kray feed on Vitis amurensis ( Vitaceae ) and Actinidia ( Actinidiaceae ) ( Omelko & Omelko 2008; Pittaway & Kitching 2021). These plants also grow in Priamurye as well. Therefore, winter air temperatures and snow cover depth, which affect the overwintering success for pupae, can be the main factors determining the northward extension of the A. naga range.
