Zhang, Yalin, Gao, Xia & Huang, Min, 2009, First record of the leafhopper genus Yangida Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae: Zyginellini) from China, with description of one new species, Zootaxa 2204, pp. 63-66 : 64-66

Yangida fasciata sp. nov.

Figs 9–23

Description. Yellowish-brown, eyes black, two parallel narrow fasciae along front edge of vertex and frons black ( Fig. 12 ), remaining part of vertex yellowish-brown except triangular white area in posterior part. Pronotum pale brown, anterior part and both sides with yellowish area, central part anteriorly white. Scutum yellowish. Scutellum white ( Figs. 9, 11 ). Face brown ( Fig. 10 ). Forewing white transparent, with long yellowish-brown streak from base to apex of clavus, hind margin of brochsome field with rectangular black patch, 1st apical cell about 2x smaller than the 2nd cell ( Fig. 15 ). Veins of hindwing brown, submarginal vein ending near m-cu1 ( Fig. 16 ).

Abdominal apodemes narrow, reaching end of 5th sternite ( Fig. 13 ).

Genital capsule elongated. Caudal lobe of pygofer with caudal apex roundish; dorsal process slender, directed ventro-caudad. Antero-ventral part of pygofer with one microseta, one medium sized seta on lower margin and few long setae at caudal margin ( Fig. 21 ). Subgenital plate with one microseta near base of narrow apical part, one macroseta subbasally and two macrosetae subapically; apex long, bifurcated ( Figs. 14, 18, 19 ). Paramere with row of setae on outer margin and row of sensory pits on inner margin; caudal part tapering (Fig, 20). Connective with extremely slim manubrium ( Fig. 17 ). Penis dorsal apodeme broad; vesicle distinct and exceeding apex of stem; gonopore subapical; processes arising basally, tapering, curved dorsad then latero-cephalad; apical part ornamented with sculpture ( Figs. 22, 23 ).

Measurement. Male 2.72 mm long (including wing).

Type specimens. Holotype: 3, China: Yunnan Prov., Sanchahe, 7 June 1991, coll. Tian Rungang; Paratypes: 63, same locality, date, and collector as holotype.

Remarks. This new species has male genitalia similar to Y. basnetti Dworakowska. However , it can be distinguished by the slender dorsal process on the caudal lobe of the pygofer ( Figs. 21 , 1, 6 ), the bifurcated apical lobe of the subgenital plate ( Figs. 14, 18, 19 , 2, 5 ), the broad dorsal apodeme of penis, and by its shorter stem and sculptured processes ( Figs. 22, 23 , 7, 8 ).

Etymology. The species name is derived from the Latin word “fascia”, referring to the long yellowish-brown streak on the forewing clavus.
