Tishechkin, Dmitri Yu., 2017, Review of the genus Oncopsis Burmeister, 1838 (Homoptera: Auchenorrhyncha: Cicadellidae: Macropsinae) of Russia and adjacent countries with description of a new species from Central Asia, Zootaxa 4216 (6), pp. 537-558 : 539

1. 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).
