Empoasca (Empoasca) apibicruris Liu, sp. nov.

(Figs. 10–18; Figs. 58–61)

Type materials: China: holotype: m#, Jianfengling (18° 43’ 14” N, 108° 49’ 45” E), Hainan Prov., 5 May 2008, 980 m, coll. Qiulei Men; paratypes: 2 m #, same data as holotype. (all in NWAFU).

Length: m# 3.0 mm.

Ground color of body yellowish-green (Fig. 61). Crown with distinct light green patch on each side of coronal suture (Fig. 58). Eyes dark-brown. Pronotum with irregular yellow patches on anterior margin of pronotum and under eyes. Forewing and hindwing semitransparent. Abdomen yellow. Legs light yellow to green (Fig. 60).

Ventral abdominal apodemes subparallel-sided, reaching segment 5 (Fig. 12). Pygofer with short dorso-apical lobe curved mediad, posterior margin broadly rounded, ornamented with 8–9 rigid setae distributed from outer to inner face of pygofer (Fig. 10); pygofer appendage not exceeding pygofer margin, arcuate distally in lateral view, apex broadened and obliquely tapered (Fig. 11). Anal appendage stout, swollen distinctly in sub-apical part, narrowing and curved anterad apically (Fig. 13). Subgenital plate in lateral view curved gradually caudodorsad apically, expanded apically; with numerous macrosetae on apical half; dorsolateral margin group A with 4–5 long stout setae subbasally and group B with 22–23 short microsetae over apical 2/3 (Fig. 18). Paramere with 4 teeth on dentifer, 9–10 setae subapically, apex bent ventrad and blunt in lateral view, evenly tapered and curved laterad in ventral view (Fig. 17). Connective slightly broader than long, posterior margin medially emarginate, strongly sclerotized along mid-line but without obvious dorsal keel (Fig. 14). Aedeagus shaft well sclerotized, unevenly tapered in lateral view; distal appendages slightly shorter than shaft, divergent at ca. 45º angle in posterior view; basal appendages slightly shorter than shaft, subparallel in ventral view (Figs. 15, 16). Gonopore terminal.

Etymology: The specific epithet is derived from the combination “ api– ” and “ bicruris ” which refers to the shape of apex shaft being furcated.

Diagnosis: The new species is similar to Empoasca albipennis Dworakowska, 1977b, but differs in having the two pairs of processes short and the pygofer appendage not forked.
