Min, Gao & Zhang, Yalin, 2013, Review of the leafhopper genus Oniella Matsumura (Hemiptera: Cicadellidae), with description of a new species from China, Zootaxa 3693 (1) : -

2. Oniella shaanxiana sp. nov.

(Figs. 2, 7, 12, 17, 56–61)

Description. Crown black medially with margins yellowish white; color pattern of pronotum and scutellum as in O. honesta , but yellowish white patches on forewing smaller (Figs. 2, 7, 12, 17).

Shape of male pygofer similar to that of O. honesta , but ventral process less intraspecific variation ( Fig. 56 ). Subgenital plate as in O. honesta , but narrowed at basal 1/3 and with single longitudinal row of macrosetae on the ventral margin ( Fig. 57 ). Style apex expanded and cheliform, basal part expanded and foot-like ( Fig. 61 ). Connective Y-shaped with arms shorter than stem ( Fig. 60 ). Aedeagal shaft curved dorsad, tubular, narrowed gradually at apex, with two pairs of slender, somewhat asymmetrical processes arising near midlength of shaft and extended distad ( Figs. 58–59 ).

Measurements. Male body length 5.2 & 5.4mm, female body length 5.9 & 6.1mm (including wing).

Material examined. Holotype: 3, China: Shaanxi Prov., Zhouzhi, Zhongnanshan, 27-June-1951. Paratypes: 1Ƥ, China: Sichuan Prov., Yaan, 8-July-1939, coll: Zhou Yao; 33, 3Ƥ, China: Shaanxi Prov., Zhouzhi, Zhongnanshan, 27-June-1951.

Distribution. China (Sichuan, Shaanxi).

Etymology. The specific epithet is derived from the province in which the holotype was collected. Remarks. O. shaanxiana can be easily recognized from other species of Oniella by the two pairs of slender processes on the ventral margin of aedeagal shaft in the basal half. Sexual dimorphism is common in this species.
