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 : 546-552

19. Oncopsis carpini (Sahlberg, 1871)

Figs. 49–51 , 164–193

Description. Coloration of males typical ( Fig. 49 ), females similar to males or pale greenish yellow ( Figs. 50–51 ). The shape of ventral margin of penis varies from almost straight to strongly concave in side view ( Figs. 164–165, 181–186 ). Branches of lower appendage of dorsal connective also variable ( Figs. 165–167, 187–193 ). Style similar with that of O. flavicollis ( Figs. 168–170 ). Abdominal apodemes of 2nd tergite in male with widely rounded or angulate lobes separated by narrow notch ( Figs. 171–180 ). We have not found any significant morphological differences between populations from Crimea ( Figs. 164–174 ), North-West Caucasus ( Figs. 175–178, 181–184, 189–193 ), and Northern Iran ( Figs. 179–180, 185–188 ).

Body length (including tegmina): ♂, 4.3–5.0 mm; ♀, 4.3–5.3 mm.

Differs from O. flavicollis by shape of the 2nd dorsal apodemes and coloration of light-coloured females (bright yellow in O. flavicollis , pale greenish yellow in O. carpini ). Differs from O. burjatica Tishetshkin, 2008 in coloration of light-coloured females, host and distribution (East Palaearctic in O. burjatica , West Palaearctic in O. carpini ). Almost indistinguishable from O. tsejensis Tishetshkin, 1992 in morphology, but differs from it in host preference.

Host. Carpinus betulus , possibly, also C. orientalis .

Distribution. Europe, mountains of Crimea, Caucasus, Transcaucasia, Northern Iran.
