Zou, Hongfen, Lin, Shuanghu, Huang, Min & Zhang, Yalin, 2022, Taxonomic study of the leafhopper genus Rufitidia (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini) from China, with descriptions of two new species, Zootaxa 5190 (3), pp. 419-424 : 424

2. Rufitidia dissidens Lin & Zhang sp. nov.

( Figs 1e–h , 3 )

Description. Vertex pale yellow, with two small brown spots, whitish towards eyes ( Figs 1e, g ). Coronal suture distinct, broad dark brownish longitudinal streak in the coronal suture accompanied with two small roundish patches laterally. Eyes black. Head slightly narrower than greatest width of pronotum ( Figs 1e, g ). Face pale yellow, with areas of white ( Fig. 1h ). Frontoclypeus area and anteclypeus posterior region light brown. Pronotum anterior region pale yellow, with two small round brown spots; central part and posterior region from brownish yellow to brown, with irregular dark brown or black patterns ( Figs 1e, g ). Forewing overall pale white, base and inner margin brownish gray ( Figs 1e, f ).

Abdominal apodemes small and short ( Fig. 3b ).

Pygofer lobe broad, with some microsetae scattered in the middle of lobe, ventro-cephalic angle and near caudal margin ( Fig. 3a ); dorsal appendage u-shaped, pointed at both ends ( Figs 3a, c ). Subgenital plate extended to hind margin of pygofer lobe, acutely narrowing at apex, with four macrosetae not far from terminal part, of which two are longer and two shorter ( Fig. 3a ). Anal tube appendage tapering apically and nearly right-angle curved ( Fig. 3a ). Style slim, apex sharp ( Figs 3e, f ). Aedeagal shaft compressed, with one pair of subapical processes extended ventrad, and two pairs of subbasal processes extended dorsad, ventral edge of shaft irregularly dentate in lateral view ( Figs 3g, h ). Connective V-shaped, manubrium short ( Fig. 3d ).

Measurement. Length of male 3.3–3.4mm (including wing).

Material examined. Holotype: ♂, CHINA, Fujian Prov., Nanping , 19 July 2017, coll. Shuanghu Lin ; Paratypes: 2♂, same data as holotype .

Remarks. This new species is similar to R. trinotata Dworakowska, 1994 , but can be distinguished by the ushaped dorsal pygofer appendage, pointed at both ends; the ventral edge of the shaft irregularly dentated in lateral view; with one pair of subapical processes extended ventrad.

Etymology. The specific epithet is derived from the Latin “dissidens” (different), referring to the dentate edge of the aedeagus.
