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 : 337-338

Asymmetrasca reflexilis, Liu and Zhang , sp. nov.

( Figs 51–60 , 116–118 )

Type materials. China: holotype ♂, Sichuan Prov., Mianning, 8.vi.1999, coll. I. Dworakowska; paratypes: 4♂♂, Sichuan Prov., Mianning, 8.vi.1999, coll. Daozheng Qin. All in NWAFU.

Length: ♂ 3.2 mm–3.4 mm.

Ground colour of body yellowish ( Fig. 118 ). Crown with light green patch on each side of coronal suture ( Fig. 116 ). Eyes brown. Pronotum with irregular patches on anterior margin of pronotum and under eyes. Forewing and hind wing semitransparent. Abdomen light yellow. Legs light green to yellow-greenish ( Fig. 117 ).

Ventral abdominal apodemes well developed, reaching midlength of segment 5, parallel-sided to broadly rounded apices ( Fig. 58 ). Male pygofer slightly narrowing caudad, with a few rigid setae on caudal-dorsal angle ( Fig. 51 ); ventral pygofer appendage tapering, slightly curved, not exceeding lobe margin ( Fig. 52 ). Anal appendage solid, with numerous serrations apically ( Fig. 53 ). Subgenital plate in lateral view, curved gradually caudodorsad apically, tapering to rounded apex; with numerous macrosetae and fine setae somewhat irregularly scattered; dorsolateral margin group A with 5 long stout setae, group B with 24–26 short microsetae on apical 2/3 ( Fig. 60 ), group C double near base, with a single row of macrosetae distally, group D irregular with numerous elongate setae. Paramere with 6–7 teeth on dentifer, several setae subapically ( Fig. 59 ). Connective broad, with anterior margin slightly emarginated medially ( Fig. 54 ). Aedeagus with preatrium straight, longer than shaft; dorsal apodeme well developed; shaft in lateral view curved dorsad, with ventral notch adjacent to gonopore, without dorsal denticuli; apical process elongate, slender, strongly curved, apex tapered and serrate ( Figs 55, 56 ).

Etymology. The specific epithet is derived from the Latin " reflexus " meaning "turned back" and refers to the reflexed aedeagal process.

Diagnosis. The new species is similar to A. kaicola Dworakowska, 1982 , but can be distinguished by the strongly curved aedeagal appendage lacking an apical bifurcation.
