Liu, Yang, Fletcher, Murray J., Dietrich, Christopher H. & Zhang, Ya-Lin, 2014, New species and records of Asymmetrasca (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) from China and name changes in Empoasca (Matsumurasca), Zootaxa 3768 (3), pp. 327-350 : 335-336

Asymmetrasca liaoensis, Liu and Zhang , sp. nov.

( Figs 40–46 , 105–108 )

Type materials. China: holotype ♂, Liaoning Prov.: Beiling Park, Shenyang, 8.viii.2009, coll. Daozheng Qin; paratypes: 2♂♂, same data as holotype. All in NWAFU.

Length: ♂ 2.9 mm–3.0 mm.

General color of body yellow-greenish ( Fig. 108 ). Crown yellowish, with obvious olive markings on each side of coronal suture ( Fig. 105 ). Pronotum broad, with irregular patches of yellow-greenish on anterior margin. Lateral parts of scutellum with cream-yellowish triangular spots. Forewing and hind wing semitransparent. Abdomen yellow. Legs pale yellow to pale green ( Fig. 107 ).

Abdominal apodemes subparallel-sided, reaching midlength of segment 5 ( Fig. 41 ). Male pygofer slightly narrowing caudad, ornamented with 7 rigid setae on each side of pygofer lobe ( Fig. 40 ); pygofer appendage slightly curved, not exceeding caudal margin of lobe in lateral view. Subgenital plate in lateral view curved gradually caudodorsad apically, expanded apically; group A with 4 moderately long setae; group B with 21 short microsetae, group C arranged in two rows of macrosetae, from medial margin to apical margin of inner side, group D irregular, with most setae short except near apex ( Fig. 46 ). Paramere long, subapically curved, dentifer with 5 teeth; 3–6 setae present preapically ( Fig. 45 ). Connective broad, with posterior margin slightly emarginate medially ( Fig. 42 ). Aedeagus with preatrium nearly as long as shaft, very broad in lateral view; dorsal apodeme relatively small; shaft somewhat sinuate, without dorsal denticuli; apical process slender, nearly straight, apex weakly bifurcated ( Figs 43, 44 ).

Etymology. The specific epithet is based on the province, Liaoning, where the holotype was collected Diagnosis. This species is similar to A. lutowa Dworakowska, 1971 , but differs in the much broader preatrium and nearly straight aedeagal process.
