Material examined. Twenty-eight specimens, including 26 specimens from the Russian Far East and South Korea (Shinohara & Beneš 1988; Shinohara & Byun 1993; Shinohara & Taeger 2007; present work). New collection data: RUSSIA: Primorskij Kraj: 1♂ (DEI-GISHym 86268), Arsenyev, Ski-Base Bodrost, 200m, 44.122°N 133.270°E, 25. V. 2016, K. Kramp, M. Prous & A. Taeger RU017 (SDEI); 1♀ (Fig. 33, DEI-GISHym 86315), 1♂ (DEI-GISHym 86314), Yakovlevka 12km NW, 250m, 44.541°N 133.366°E, 27. V. 2016, K. Kramp, M. Prous & A. Taeger RU019 (SDEI). SOUTH KOREA: Gangwon-do: 1♀, Mirugam (Bukdaesa), 1,300 m, Odaesan Mts ., 4. VI. 2002, A. Shinohara (NSMT).

Distribution. Russia (Tomskaja Oblast’, Khabarovskij Kraj, Primorskij Kraj), North and South Korea, China (Jilin).

Host plant. Unknown.

Remarks. The specimens recorded from Zhejiang Province, China, as O. armata by Shinohara & Xiao (2006) belong to O. atra Shinohara & Wei, 2016 (Shinohara & Wei 2016). In China, O. armata has been found only in the northeastern part (Jilin).

Morphologically, this species closely resembles O. kumamotonis particularly in having a comparatively long flagellomere 1 and a similar structure of the male clypeus. Shinohara (2002b) placed these two species in his O kumamotonis complex of the O. luteicornis subgroup of the O. luteicornis group. This placement was supported by our NaK analysis, where the nearest neighbour of O. armata, diverging by a minimum of only 0.2%, was O. kumamotonis, and O. armata and O. kumamotonis formed a clade with 100% UFBoot support (Fig. 153). However, in the COI analysis, the nearest neighbour, diverging by a minimum of 2.6%, was O. viriditibialis, with which O. armata formed a clade with 100% UFBoot support (Fig. 138). The maximum p -distance between three specimens of O. armata from Primorskij Kraj was 0.6% in COI and 0% in NaK.

It is interesting that the known distributions of O. armata and O. kumamotonis do not overlap. Onycholyda armata is a continental species and O. kumamotonis occurs only in Japan and Sakhalin.
