Figs 2, 5

Monima aoyamensis Matsumura, 1926: 13 (type locality: Japan: Hokkaido, Aoyama near

Kutchan, and Sapporo).

MATERIAL. Russia: Sakhalinskaya oblast, Sakhalin Island, near Yuzhno-Sakhalinsk, 5

km NE of Novo-Aleksandrovsk , 47°05' N, 142°46' E, 10–25.V 2019, 5♂, leg. O. Kuporosov

[ BB].

DISTRIBUTION. Russia (new record): Sakhalin Island. – Japan: Hokkaido, Honshu,

Shikoku, and Kyushu Islands (Matsumura, 1926; Inoue et al., 1982).

REMARKS. Externally Orthosia aoyamensis resembles O. incerta (Hufnagel, 1766) but with noticeable basal, antemedial and postmedial lines on forewings; medial field is usually darker than ground colour of forewings. In male genitalia ventral margin of cucullus with strong concavity and without noticeable pollex. Most likely in the southern part of Sakhalin

O. aoyamensis is an autochthonous species and its late discovery here can be explained by the poor knowledge of the spring aspect of Noctuidae fauna of this territory.
