Zhang, Bin, 2010, New species of macropsine leafhopper genus Pedionis Hamilton (Hemiptera, Cicadellidae) from China, with a key to Chinese species, Zootaxa 2484, pp. 53-60 : 58-59

Pedionis (Pedionis) spinata sp. nov.

( Figs. 1 C–D, 3 B, 5 A–F)

Description. Length. Male 3.9 mm.

Coloration. Pale brown with dark brown spots. Anteclypeus dark brown in apical half. Pronoutm ( Fig. 1 C, D) darker than head. Scutellum ( Fig. 1 C) with central area darker than lateral and caudal areas. Forewing ( Fig. 1 C, D) brownish with apical areas of claval vein, apex of clavus and irregular spot near apex of corium, dark brown; venation dark brown with white spots. Legs brown with paler markings.

Morphology. Body comparatively slender and small. Clypeus expanded; anteclypeus tapered. Pronotum as long as scutellum. Hind tibial spinulation R1 11, R2 9, R3 5.

Male genitalia. Pygophore ( Fig. 5 A) without caudo-dorsal spine usually found in Pedionis , setae on ventral margin relatively stout. Subgenital plate, style and connective similar to that in P. garuda . Aedeagus ( Figs. 5 C, D) shaft with triangular lobe-like projection on dorsal margin, with subapical lateral expansion ventro-posterior view, with pair of small spine-like processes subapically; dorsal connective simple, distal part curved with marginal serrations.

Female. Unknown.

Distribution. China: Hainan (Mt. Wuzhi)

Material examined. Holotype. Male, China: Hainan province, Mt. Wuzhi (18°77΄N, 109°50΄E), 1200 m, 15 July 2007, collected by Zhang Bin.

Remarks. Pedionis spinata resembles P. rufoscutellata Huang & Viraktamath externally, but differs in having the posterior margin of the pygophore truncate apically without a ventral process; and subapical margin of the aedeagal shaft with a large triangular expansion along the ventral margin.

Etymology. The specific name refers to spine-like process of the aedeagal shaft.
