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.
