( Figs 1–2 View Figure , 5–6 View Figure , 9–18 View Figure )

Male. Yellowish brown. Vertex ( Fig. 1 View Figure ) with two small black spots closer to adjacent eyes than to median line. Face pale yellow ( Fig. 5 View Figure ); eyes and ocelli lemon yellow. Pronotum ( Fig. 1 View Figure ) yellowish brown with pair of triangular black marks on anterior margin, posterior margin grayish white. Scutellum with basal triangles blackish brown, a round dark spot on either side of median line. Forewings ( Fig. 1 View Figure ) yellowish brown, veins dark brown except inner claval vein white.

Male genitalia. Pygofer lobe ( Figs 11–12 View Figure ) broad, ventral margin with 14–15 denticles; anal collar ( Figs 11– 12 View Figure ) with arms tapered to acute apex with subapical ventral tooth. Apophysis of style ( Fig. 13 View Figure ) bearing approximately 13–14 fine lateral setae distally. Aedeagus ( Fig. 16–17 View Figure ) with well developed dorsal apodeme and short preatrium; shaft tubular, dorsally curved with elongate dorsal lamella on each side and short elongate subapical process on each side above gonopore.

Male dorsal basal abdominal apodemes ( Fig. 10 View Figure ) shorter than ventral ones, attaining posterior margin of sternite III.

Female. Color ( Fig. 2 View Figure ) similar to male but face brighter yellow, triangular black marks on pronotum smaller and scutellum markings paler.

Female genitalia. Posterior margin of sternite VII convexly rounded medially. Second valvulae ( Fig. 18 View Figure ) regularly broadened in lateral view, bearing approximately 13 teeth along dorsal margin.

Measurements (mm). Male: body length 5.4–5.5, face length 1.43–1.5, width 1.8–1.85; distance between ocelli 0.44–0.55; distance from ocellus to eyes 0.32–0.33; medial length of pronotum 0.58–0.63, width 1.55–1.58; scutellum length 0.85–87, width 1.13–1.25. Female: body length 5.85–5.95, face length 1.55–1.56, width 1.93– 1.95; distance between ocelli 0.54–0.57; distance from ocellus to eyes 0.33–0.35; medial length of pronotum 0.63– 0.68, width 1.63–1.65; scutellum length 0.95–0.98, width 1.23–1.25.

Material examined. Holotype: ♂, China, Yunnan Province, Pianma County, 11. viii.2017, Bin Zhang  . Paratypes: 1♂, 3♀♀, same date as holotype.

Host plant. Unknown.
