Oncopsis sulphurea Anufriev, 1967 Figs. 1–5 , 59–63 Description. Cuticle very smooth, shiny. Males from Southern Maritime Territory yellow with dark pattern on face, pro- and mesonotum ( Figs. 1, 4–5 ); forewings strongly infumose with yellowish scutellar margins and transparent areas on costal margins. Males from Kurile Islands brownish yellow, dark pattern is almost absent ( Fig. 2 ). Females from mainland and island populations bright yellow without dark pattern ( Fig. 3 ). Penis rather narrow in caudal view ( Fig. 59 ), with ventral margin convex in side view ( Figs. 60–61 ). Lower appendage of dorsal connective slightly bent ventrally, with forked apical part C-shaped, upper branch somewhat longer and wider than lower one ( Figs. 61–62 ). Style parallel-margined, with acute tip ( Fig. 63 ). Body length (including tegmina): ♂, 5.0– 5.6 mm ; ♀, 5.5–5.8 mm . Differs from most other Russian species in coloration. In external appearance, dark colour form somewhat similar to O. nitobei ( Matsumura, 1912 ) , O. furva Anufriev, 1977 , and O. sepulcralis Anufriev, 1967 ( Figs. 6–7, 10–12 , and 16–17). Differs from all Russian species by the shape of the lower appendage of dorsal connective. Host. Betula sp. in Russia , B. ermanii in Japan ( Hayashi et al ., 2005 ). Distribution. Russia : Southern Maritime Territory (Southern Sikhote-Alin’ Mtn. Ridge), Kurile Islands (Shikotan, Kunashir); Japan : Hokkaido , Honshu ( Hayashi et al ., 2005 ).
