Type material.

Holotype: male, Kuankuoshui, Guizhou Province, 14 August 2010, coll. Xiaofei Yu. Paratypes: 1 male, Shiwandashan, Guangxi Province, 4 May 2011, coll. Rong Huang; 1 male, Liupanshui, Guizhou Province, 2 June 2012, coll. Maofa Yang, Zhijiang Bai and Xiaofei Yu.

Length. Male: 4.0-4.1mm.

Green to yellowish (Fig. 18a). Crown with a green patch each side of coronal suture (Figs 18a, 20a). Face in some species with an off-white longitudinal stripe on anteclypeus (Figs 19b, 21b). Scutellum with a whitish stripe medially (Figs 18a, 20a). Forewing with RP and MP’ stalked at base (Fig. 22).

Male ventral abdominal apodemes reaching segment 4 (Fig. 2). Male pygofer lobe with dorsal margin oblique and apical margin straight in lateral view, with fine setae adjacent apical margin; ventral pygofer appendage shorter than pygofer, tapering caudad, subapically denticulate; dorsal bridge about 1/3 length of pygofer (Figs 1, 3, 4). Subgenital figs elongate, with 20 macrosetae arranged obliquely in two basal rows centrally and a single distal row on lateral margin, ca. 25 elongate fine setae and medial margin with 6 basal group macrosetae followed by ca. 16 spine-like setae (Figs 1, 5). Paramere as in Fig. 6. Aedeagus with elongate preatrium; shaft slightly expanded near apex in lateral view, tapered from base to apex in ventral view, apical 1/3 with numerous irregular denticles dorsally (Figs 1, 7, 8). Anal tube process slightly sinuate (Fig. 1). Connective lamellate (Fig. 6).

Etymology.

The new species name alludes to the dorsal denticles on the aedeagal shaft.

Remarks.

The new species is similar to Empoasca (Empoasca) borowikae Dworakowska, 1976 but differs in having the male ventral abdominal apodemes reaching segment 4, ventral pygofer appendage denticulate near apex and apical 1/3 of aedeagus with dorsal denticles. The new species is also similar to Empoasca (Empoasca) gutianensis Liu, 2011 but differs in the aedeagus without denticles ventrally and anal tube process sinuate.
