( Figs. 10–12 )

Description. Male. Body rather small. Vertex of head divided into two tubercles by a longitudinal furrow. Lateral ocelli occupying almost 4/5 of the tubercles. Lateral lobes of pronotum slightly concave, posterior margin truncate. Fore femora without spines, internal genicular lobe with an elongate movable spur; fore tibiae beneath with 2 external spurs, 1 internal spur and 2 apical spurs. Internal and external genicular lobe of mid femora both with an elongate movable spur, mid tibiae beneath with 3 external spurs, 1 internal spur and 2 apical spurs, above with 2 external spurs, 2 internal spurs and 2 apical spurs. Internal genicular lobe of hind femora with a small spine, hind tibiae with 19–20 internal spines and 18–20 external spines above, arrange sparsely. Supra inner-apical spur of hind tibiae longer than hind metatarsus. Hind metatarsus compressed, with 2–3 small spines and 1 apical spine dorsally. The distance between the paired styli almost equal to styli. Epiproct with 2 pair dentiform spines (one pair at the middle part, another pair at apical part) ( Fig. 10 ).

Female. Unknown.

Coloration. Body light yellow. Frons dark. Lateral ocelli yellowish. Legs with some streaks.

Measurements. (length in mm) Body ♂ 13.0; pronotum ♂ 5.0; fore femora ♂ 6.5; hind femora ♂ 15.0; hind tibiae ♂ 14.0; hind metatarsus ♂ 3.0.

Specimens studied. Holotype, 1♂, Pianmazhen, Lushui , Hainan, alt. 2300m, 2010-VII-6 ~7, collected by Bi Wen-Xuan.

Distribution. China (Yunnan).

Diagnosis. This species is distinctive from other species in this genus because of its male epiproct with 2 pairs of dentiform spines (a pair of lateral spines and a pair of apical spines).

Etymology. The specific epithet derived from the male epiproct with four small spines.
