Figs 11–14

MATERIAL. Amurskaya oblast : Blagoveshchensk, 8.X 2016, 1♂ .

DISTRIBUTION. Russia (Magadanskaya oblast, Kamchatka Peninsula, Amurskaya oblast , Khabarovskii krai, Sakhalin Island). Far Eastern sub-oceanic boreal forest species .

NOTES. A little known species related to the American Operophtera bruceata

(Hulst, 1886). The general range of O. peninsularis is uncertain; in the Amur basin it is sympatric with the similar on appearance, usually abundant species O. brunnea ,

which can mask the presence of O. peninsularis . Externally, O. peninsularis differs from O. brunnea by the narrower forewings and a dark gray coloration, by more distinct transverse lines delimiting the medial field, and by more acute fracture of the postmedial transverse line on the vein M 1, ( Fig. 8 vs. Fig. 11 ), and in the male genitalia by the wider valvae, by longer and thinner uncus, by much broader saccus and by more massive basal process of aedeagus ( Figs 12–14 vc. Figs 9, 10 ). The new locality of O. peninsularis is situated considerably westward to the nearest known locality in Khabarovskii krai (Komsomolsk-na-Amure).
