Material examined. Forty specimens, including the type series. Thirty-nine specimens are from the Russian Far East and North and South Korea ( Shinohara 1987b; Shinohara & Byun 1993; Shinohara & Lee 1997; Shinohara & Taeger 2007; Shinohara & Tripotin 2021a, b; present work). New collection data: RUSSIA: Primorskij Kraj: 1♀ ( Fig. 38 , DEI-GISHym 86743), Partizansk SSW, 140m, 43.073°N 133.074°E, 9. VI. 2016, K. Kramp, M. Prous & A. Taeger, RU044 ( SDEI). SOUTH KOREA: Gangwon-do: 2♀ 1♂, Mirugam (Bukdaesa), 1,300 m, Odaesan Mts ., 29. V.–1. VI. 1998, A. Shinohara ( NSMT) ; 1♀, same locality, 2. VI . 2002 , A. Shinohara ( NSMT).

Distribution. Russia (Khabarovskij Kraj, Primorskij Kraj), North and South Korea, China (Heilongjiang) ( Shinohara 1992a).

Host plant. Rosaceae : Agrimonia pilosa Ledeb. ( Shinohara & Lee 2011).

Remarks. This species has much in common with O. decorata Shinohara, 1985 , from Japan, in adult and larval morphology and host plant ( Shinohara 1987b; Shinohara & Lee 2011). In our molecular analyses, the two species were also quite close, diverging by a minimum of 1.1% in COI and 0.3% in NaK. The two species formed a clade with 100% UFBoot support in both COI and NaK analyses ( Figs 139 , 153 ). However, we treat them as distinct species, because the differences between them ( Shinohara 1987b) are small but quite constant.

The newly acquired female specimen from Russia ( Fig. 38 ) has extensively orange-marked temples and vertex, but is otherwise not distinguishable from other specimens ( Fig. 37 ) ( Shinohara 1987b). The pale coloration of the head of this specimen is asymmetrical suggesting its aberrant nature ( Fig. 38e ).
