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 : 539-540

3. Oncopsis furva Anufriev, 1977

Figs. 10–15 , 69–71

Description. Face yellow with dark pattern; all spots merged with each other ( Figs. 13–15 ). In males and dark females pro- and mesonotum almost entirely black ( Figs. 10–11 ). In light females pronotum yellow with typical dark pattern, but mesonotum retains almost black coloration ( Fig. 12 ). Forewings strongly infumose with transparent areas at end of clavus and along costal margin; in light specimens claval suture also transparent.

Penis of typical shape, with ventral margin convex in side view ( Figs. 69–70 ). Lower appendage of dorsal connective bifurcated, both branches with finely serrated inner margins, upper branch distinctly longer than lower one, notch between the branches is more or less elongated ( Fig. 70 ). Style parallel-margined, with acute tip ( Fig. 71 ).

Body length (including tegmina): ♂, 4.2–4.6 mm; ♀, 4.7–4.9 mm.

Differs from most other Russian species by dark coloration; in external appearance somewhat similar with O. nitobei , O. sepulcralis , and dark males of O. sulphurea ( Figs. 1, 6–7 , and 16–17). In the shape of the lower appendage of dorsal connective similar to O. sepulcralis , but differs by elongated notch between branches of appendage (more or less round in O. sepulcralis ) and host preference.

Host. Alnus japonica on Kurile Islands and in Japan ( Hayashi et al., 2005).

Distribution. Russia: Kurile Islands (Kunashir); Japan: Hokkaido, Honshu ( Hayashi et al., 2005).

Remark. In the original description the male holotype and 4 paratypes (3 males and 1 female) collected in Dubovoe near Golovnino, Kunashir, 18–23.VII.1973 by I.M. Kerzhner are listed ( Anufriev, 1977). In addition, I have investigated one female with the labels “Sernovodsk, Kunashir, Kerzhner, 26.VIII.1973 ” (printed, in Russian), “From Alnus japonica ” (handwritten by G.A. Anufriev), and “Paratypus Oncopsis furvus (sic!) sp. n. Anufriev, 1975” (red paper, “Paratypus” printed, other text handwritten by G.A. Anufriev), ZIN and one female with the labels “The Golovnin Volcano, Kunashir, Kerzhner, 26.VIII.1973 ” (printed, in Russian) and “Paratypus Oncopsis furvus (sic!) sp. n. Anufriev, 1975” (red paper, “Paratypus” printed, other text handwritten by G.A. Anufriev), coll. Anufriev.
