| Summary: | 4. Oncopsis sepulcralis Anufriev, 1967 Figs. 16–20, 72–76 Description. Darkest males almost entirely black with several small light spots on face; forewings strongly infumose with transparent areas on clavus and at costal margin (Figs. 16, 18). In lighter males and in females upper third of face yellow, pronotum and forewings less dark (Figs. 17, 19–20). Penis of typical shape, with ventral margin convex in side view (Figs. 72–73). Lower appendage of dorsal connective bifurcated, both branches with finely serrated ends, upper branch only slightly longer than lower one, notch between branches more or less round (Figs. 73–74). Style parallel-margined, with acute tip (Figs. 75–76). Body length (including tegmina): ♂, 4.5–4.8 mm; ♀, 4.2–4.8 mm. It is notable that in this species females are the same size or are even smaller than males as also reported in O. taibaiensis Yang, Zhang, 2015 (Yang & Zhang, 2015). Differs from other dark-coloured species from Russian Far-East (O. sulphurea, O. nitobei, and O. furva) by shape of black pattern on face. Shape of male genitalia most similar to O. furva, but differs by wider, rounded notch between branches of lower appendage of dorsal connective. Also, differs from O. nitobei and O. furva by host specialization. Host. Collected from Betula platyphylla and B. davurica in the Southern Maritime Territory and from Betula ermanii on Kunashir and in Japan (Hayashi et al., 2005). Distribution. Russia: Southern Maritime Territory, Southern Sakhalin, Kurile Islands (Shikotan, Kunashir); Japan: Hokkaido, Honshu (Hayashi et al., 2005). Published as part of 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, pp. 537-558 in Zootaxa 4216 (6) on page 540, DOI:10.5281/zenodo.242421 |
