Lectotype designation. Gussakovskij (1935) used a pair of specimens, a male and a female, for describing this species but did not designate a holotype. We hereby designate the female specimen (https://doi.org/10.6084/ m9.figshare.16832095) in ZIL as a lectotype. It is labeled “Прим.[орскаЯ] обл.[асть]. Между ЛаЗаревым и Чома у о-ва Чакмут, Солдатов, 31.VIII.911”. According to Belokobylskij (pers. comm.), the locality is to be expected between Lazarev (52°11'42"N 141°27'43"E) and Bol’shoy Choma Island (52°23'29.9"N 141°12'24.0"E) [in Khabarovskij Kraj] near a spring or a river, as the collector V. K. Soldatov was an ichthyologist and insect collector. The date on the label corresponds to 13.IX.1911 in the Gregorian calendar.

Material examined. About 295 specimens, including the lectotype. A total of 183 specimens are from the Russian Far East and South Korea (Gussakovskij 1935; Shinohara 1980, 1992b; Shinohara & Byun 1993; Shinohara & Lee 1997; Shinohara & Taeger 2007; present work).

Distribution. Russia (East Siberia, “ Amur ”, Khabarovskij Kraj, Primorskij Kraj, Sakhalin), North and South Korea, Japan (Hokkaido, Shikotan Is.) (Shinohara & Byun 1993), China (Inner Mongolia, Heilongjiang, Liaoning) (Shinohara & Byun 1993; Xiao & Chen 2005; Sundukov 2015).

Host plant. Rosaceae: Sorbaria sorbifolia (L.) A. Braun var. stellipila Maxim. (Shinohara 1980; Shinohara & Hara 1999). Records of Populus tremula L. and Spiraea sp. (Lee et al. 2019) need confirmation; the former is most probably erroneous.

Remarks. Adults of this species are locally abundant around Sorbaria bushes in the right season. The larvae are gregarious webspinners on this plant (Shinohara 1980; Shinohara & Hara 1999). The maximum p -distance between specimens from Russia and Japan was 2.0% (n=13) in COI and 1.2% (n=10) in NaK. The nearest neighbour, diverging by a minimum of 6.0% in COI and 0.9% in NaK, was N. iridescens . These two species formed a clade in the trees (Figs 137, 152), as discussed above.
