Siglophora sanguinolenta (Moore, 1888) ( Figs 2H–J )

Material examined. 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: 2 ♂, 1 ♀, 5– 7.08.2020 (Koshkin 2021) ; 1 ♂, 26.06.2021 (E.S. Koshkin leg.); 1 ♀, 2.07.2021 (E.S. Koshkin leg.); 14 ♂♂, 24 ♀, 23– 29.07.2021 (E.S. Koshkin leg.); 21 ♂, 1 ♀, 6– 9.09.2021 (E.S. Koshkin leg.); 1 ♂, 26.09.2021 (E.S. Koshkin leg.)

Remarks. The species was first recorded in the Russian Federation based on three specimens collected in the Bikin district of the Khabarovsk Kray in early August 2020 (Koshkin 2021) ( Fig. 1 ). In 2021, several dozen specimens of different condition degrees, from damaged to completely fresh ones, were found in the same locality. For instance, more than 20 specimens were encountered within one night (July 27/ July 28, 2021). This indicates overwintering success of S. sanguinolenta in the southern Khabarovsk Kray. According to the nearest weather station «Bikin», the average temperature of the cold period (October 2020 through March 2021) was –8.5°C; the absolute minimum temperature was –33.8°C, while the average snow cover depth was 13.9 cm (http://rp5.ru). All these facts, as well as the presence of Quercus mongolica , a host plant of larvae ( Sohn et al. 2017), are indicative of successful naturalization of the species in Russia. S. sanguinolenta probably has two or three generations per year in the southern Khabarovsk Kray; the flight periods of these generations partially overlap and last from mid-June till late September. The main range of the species involves North India, Nepal, the Korean Peninsula, China (including Taiwan), and the Philippines ( Kononenko et al. 1998). The vicinity of Wonsan city located in the southern part of North Korea had been previously known as the northernmost locality of the species (National Institute of Biological Resources of Korea 2021).
