Xing, Ji-Chun, Dai, Ren-Huai & Li, Zi-Zhong, 2010, Two new species of the genus Japananus Ball, 1931 (Hemiptera: Cicadellidae: Deltocephalinae), Zootaxa 2415, pp. 63-68 : 65-66

Japananus meilingensis sp. nov.

Figs. 7–15

Description. Medium sized leafhoppers, body light green.Vertex yellownish, anterior margin black. Eyes brown. Pronotum pale-yellow, median area gray black. Scutellum brownish, transverse impression distinct. Dorsal surface of abdomen yellowish, ventral surface dark brown medially. Forewings and hindwings transparent, with transverse brown bands on hyaline forewings. Legs dark brown.

Head anteriorly triangularly produced, longer than width between eyes, narrower than pronotum ( Fig.7 ). Vertex medially depressed, transition between face and vertex angular, carinate, disc depressed ( Fig.7 ). Face shagreened, frontoclypeus widened posteriorly, about 3 times as wide at bases of antennae as at apex. Anteclypeus expanded at apex ( Fig.8 ). Ocelli on anterior margin, contiguous with eyes. Pronotum broad, approximately equal length with vertex, lateral margin carinate, anterior margin rounded and posterior margin approximate straight. Scutellum triangular, its length slightly shorter than length of pronotum, with transverse suture curved and depressed ( Fig.7 ). Forewings with four apical cells and three subapical cells, 3.2 times as long as greatest width; outer anteapical cell quadrangular, smaller than median anteapical cell, appendix well developed.

Male genitalia: pygophore slightly longer than high, with a few stout setae along ventro-caudal margin, ventral margin rather expanded, without processes ( Fig.9 ). Valve large, subtriangular ( Fig.10 ). Subgenital plate with a caudal attenuated process, without stout setae ( Fig.11 ). Aedeagus with paired shafts, U-shaped in ventral view, each aedeagal shaft with a recurved subapical process, and each subapical process with a little spine process; gonopore subapical ( Figs 12, 13 ).Connective slender, Y-shaped with arms forked apically and its arms shorter than stem ( Fig.14 ). Style slender, elongate, with strongly laterally curved caudal apex of apophysis ( Fig. 15 ).

Female seventh sternum similar to a long triangle, the central margin strongly produced.

Measurement. Length (including tegmen): 3, 4.1–4.3 mm; Ƥ, 5.5– 4.7 mm.

Type Material. Holotype 3, China: Jiangxi Prov., Nanchang City, Meiling, 1 July 1992, coll. Yujian Lin (Jiangxi Agricultural University). Paratypes: 1Ƥ, Jiangxi Prov., Nanchang City, Meiling, 7 July 1992, coll. Yujian Lin (Jiangxi Agricultural University); 13, Jiangxi Prov., Nanchang City, Meiling, 10 July 1993, coll. Yujian Lin (Jiangxi Agricultural University); 1Ƥ, Jiangxi Prov., Nanchang City, Meiling, 8 July 1993, coll. Yujian Lin (Jiangxi Agricultural University); 1Ƥ, Jiangxi Prov., Nanchang City, Meiling, 27 July 1993, coll. Yujian Lin (Jiangxi Agricultural University).

Remarks. This species is similar to Japananus bicurvatus Xing, Dai & Li but can be distinguished by the the shape of the aedeagal shafts in ventral view and shape of their processes, and connective with arms forked apically.

Etymology. The species name is derived from the type locality Meiling.
