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 : 123-124

3. Drabescus multidentatus sp. nov.

Figs. 34–35, 48–53.

Description. Length (including tegmen): ♂, 7.8–8.1 mm.

Body general appearance as in D. cuspidatus sp. nov., but dark brown. Face dark brown. Dorsum with two narrow, posteriorly divergent yellow bands from crown to scutellum, dark on both sides (Figs. 34–35). Forewings translucent, with many brown spots or few white maculae. Hind femur with apical setae 2+2+1.

Male genitalia. Pygofer side nearly triangular, ventral margin sinuated, narrowing to falcate apex, dorsal margin with several setae (Fig. 48). Valve broadly V-shaped, subgenital plate with lateral margin roundly tapered to middle, with numerous fine lateral setae, distal half fingerlike, and with marginal setae (Fig. 49). Style straight and slender (Fig. 50). Aedeagus with shaft slender, straight and elongate in lateral view, columnlike with apex slightly expanded, in ventral view tapered to slender point distally; pair of basal processes arising ventrally at base and extended nearly to apex, tapered, with dorsal margins irregularly toothed, slender and closely appressed along midline in ventral view; conopre preapical on posterior surface (Figs. 51–52). Connective Y-shaped, shaft longer than arms (Fig. 53).

Material examined. Holotype: ♂, CHINA: Shanxi Province, Lishan National Nature Reserve, 22. VII. 2012, collected by Song Qiong-zhang.

Remarks. This species is similar to D. minipenis Zhang & Chen and D. piceatus Kuoh , but can be distinguished from them by its aedeagus in ventral aspect with a shorter spinous basal process, and paired long basal processes dorsally sinuate in lateral aspect.

Etymology. New species name is derived from the Latin word “ multidentatus ”, referring to the many toothlike aedeagal processes.
