Wang, Jia-Jia, Qu, Ling, Xing, Ji-Chun & Dai, Ren-Huai, 2016, Three new species of the leafhopper genus Drabescus Stål (Hemiptera: Cicadellidae: Deltocephalinae) from China, Zootaxa 4132 (1), pp. 118-126 : 120-122

1. Drabescus cuspidatus sp. nov.

Figs. 30–31, 36–41.

Description. Length (including tegmen): ♂, 6.4–6.7 mm.

Body yellow-brown (Figs. 30–31). Pronotum and scutellum pale yellow, with brown spots. Forewings translucent, with pellucid transverse band at middle. Veins brown, appearing as discontinuous brown bands. Eyes, antenna fossa, frons and anteclypeus brown to dark.

Crown arched forward, slightly prominent; ocelli marginal, separated by about 3 times distance from ocellus to adjacent eye; antenna situated slightly above midheight of eye, laterofrontal sutures on face extended to corresponding ocellus; anteclypeus gradually broadened from base to apex. Pronotum and scutellum with many transverse striations lots of thin horizontal grain, scutellar suture distinct. Hind femur with apical setae 2+2+1.

Male genitalia. Pygofer side base broad, apex narrowed, ventral margin serrate, without enlarged setae (Fig. 36). Valve nearly trapezoidal, subgenital plate nearly triangular, with fine marginal setae (Fig. 37). Style slender, base broad, apex narrowed and rounded (Fig. 38). Aedeagal shaft without processes, in dorsal aspect broadened from base to midlength then gradually narrowed to apex, apex truncate laterally; gonopore apical (Figs. 39–40). Connective Y-shaped with stem as long as arms (Fig. 41).

Material examined. Holotype: ♂, CHINA: Hainan Province, Jianfengling, 17–20. IV. 2009, collected by Hou Xiao-hui & Zhang Xin-Feng; Paratype: 3 ♂♂, same data as holotype; 1 ♂, Guangxi Autonomous Region, Nonggang National Nature Reserve, 8. V. 2012, collected by Fan Zhi-hua.

Remarks. This species is similar to D. nigrofacialis (Matsumura) , recorded from India, but can be distinguished from the latter by its pygofer without a strongly depressed posterior margin but produced into a straight and short process, and by the gradually narrowed aedeagal shaft in ventral view.

Etymology. The new species name is derived from the Latin word “ cuspidatus ”, referring to the short tapering processes of the pygofer.
