Empoasca (Empoasca) undulata Zhang & Liu , sp. nov.

( Figs.45–53 ; 93–95)

Type materials. China: holotype: 3, Chenzhou (25° 46’ 59” N, 113° 01’ 06” E), Hunan Prov., 3 August 1985, coll. Yalin Zhang; paratypes: 2 3, same data as holotype (all in NWAFU).

Length: 3 3.0 mm.

Ground color of body yellow to light brown. Crown with very light brown patch on each side of coronal suture (fig. 93). Eyes black centrally, silver marginally. Pronotum with irregular patches on anterior margin of pronotum and under eyes. Forewing and hindwing semitransparent. Abdomen yellow. Legs light yellow to light green.

Ventral abdominal apodemes well developed, parallel-sided, reaching segment 5. Pygofer with short dorso-apical lobe curved mediad, narrowing to apex of lobe, ornamented with two groups of setae, 10–12 rigid setae along dorsal margin of lobe, another group on centre of lobe, with some slim setae (fig. 45, 46); pygofer appendage in lateral view curved dorsad to follow posterior margin of pygofer, extending beyond pygofer, central part of pygofer appendage sinuate, then tapering to apex (fig. 47). Anal appendage stout, swollen distinctly at mid-length, with numerous small teeth posteroventrally (fig. 50). Subgenital plate in lateral view, curved gradually caudodorsad apically, not expanded apically, tapering to rounded apex; with numerous macrosetae and fine setae somewhat irregularly arranged; dorsolateral margin with 4–5 long stout setae subbasally, 16–18 short microsetae on almost entire length (fig. 53). Paramere with 5 teeth on dentifer, 8–11 setae subapically (fig. 52). Connective broad, anterior margin medially emarginate (fig. 51). Aedeagus in lateral view with preatrium long, pair of long process arising from shaft near dorsal margin, tapered to acute apex, aedeagus shaft compressed, truncate apically and with long apical appendage from ventral margin (figs. 48, 49). Gonopore in centre of broadly truncate apex.

Etymology. The species name is derived from “ undulates ”, and refers to the sinuate middle part of the pygofer processes.

Distribution. China (Hunan).

Diagnosis. The new species is similar to Empoasca gucia Dworakowska, 1977 , but differs in the sinuate central part of the pygofer processes, and in having the aedeagus shaft compressed and with a long appendage from the apical ventral margin.
