Liu, Y., Qin, D. Z., Fletcher, M. J. & Zhang, Y. L., 2011, Four new species of Empoasca (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) and one new record from China, Zootaxa 3070 (1), pp. 29-39 : 37

Empoasca (Empoasca) lijiangensis Liu , sp. nov.

( Figs. 45–53 ; Figs. 74–77 )

Type materials: China: holotype: m#, Lijiang (26° 53’02” N, 100° 13’32” E), Yunnan Prov., 13 November 1999, 2300 m, coll. Daozheng Qin ; paratypes: 7 m #, same data as holotype. (all in NWAFU) .

Length: m# 2.9 mm.

Ground color of body yellowish-green ( Fig. 77 ). Crown with yellow patch on each side of coronal suture ( Fig. 74 ). Eyes black. Pronotum with yellow irregular patches on anterior margin of pronotum and under eyes. Forewing and hindwing semitransparent. Abdomen yellowish-green. Legs light yellow to green ( Fig. 76 ).

Ventral abdominal apodemes short, only reaching segment 3, parallel-sided ( Fig. 47 ). Pygofer in lateral view with posterior margin broadly rounded; 13–14 stout setae in group along posterior margin, few slim setae near stout setae group ( Fig. 45 ); pygofer appendage following posterior margin of pygofer, not extended beyond pygofer, broadly bifurcated with dorsal branch much longer than ventral branch ( Fig. 46 ). Anal tube broad at base, tapering and slightly sinuate toward apex ( Fig. 49 ). Subgenital plate in lateral view, curved gradually caudodorsad apically, not expanded apically; with numerous macrosetae and fine setae somewhat irregularly arranged; dorsolateral margin group A with 5 long stout setae subbasally and group B with 18–19 short microsetae on apical half ( Fig. 53 ). Paramere with 5 teeth on dentifer, 4–5 setae subapically, apex nearly straight in lateral view, curved laterad in ventral view ( Fig. 52 ). Connective broader than long, posterior margin medially emarginate ( Fig. 48 ). Aedeagus in lateral view with preatrium long, aedeagal shaft curved dorsally, narrowing to apex ( Figs. 50, 51 ). Gonopore terminal.

Etymology: The species name is derived from the location “Lijiang” in Yunnan Province where the new species was collected.

Diagnosis: The new species is similar to Empoasca furcata Vilbaste, 1968 , but differs in having the pygofer appendage furcated apically in lateral view.
