( Figs 7–12 )

Type material. Hඈඅඈඍඒඉൾ: CHINA: Yඎඇඇൺඇ: ♁ ( DALU: CN- 21Di00028), Nujiang Lisu Autonomous Prefecture, Gongshan County, western slope of the Peacock Mountain, 28°00′41.60″N, 98°43′13.15″E, 2510 m, 13.vii.2021, leg. Ji-Shen Wang & Guo-Cong Huang. Pൺඋൺ- ඍඒඉൾ: 1 ♀ ( DALU: CN 21Di00029), same data except 28°02′42.29″N, 98°44′43.83″, leg. Guo-Cong Huang.

Diagnosis. The new species can be readily recognized by the combination of the following characters: 1) head yellow, lacking black spots on vertex ( Fig. 7 ); in males, 2) A5–A9 mostly black ( Fig. 7 ); 3) paramere with ventral branch extremely short and barb-like ( Fig. 9 ); and in females, 4) medigynium with basal portion of main plate broader than base of posterior arms ( Fig. 12 ).

Description. Measurements (mm). Male (holotype): AtL 9.8, AbL 9.5, BL 13.6, FL 13.2, FW 3.3, HL 12.3, HW 3.2. Female (paratype): AtL 13.8, AbL 8.7, BL 13.0, FL 15.9, FW 4.1, HL 14.4, HW 3.8.

Male. Head ( Fig. 7 ). Vertex yellow without black spots. Ocellar triangle black. Rostrum yellow, with two black frontal stripes.

Thorax ( Fig. 7 ). Pronotum with five black thick setae along each side of anterior margin. Meso- and metanotum black laterally, with broad yellow median stripe.

Wings ( Fig. 7 ). Membrane with slight grayish tinge, hyaline, lacking distinct markings, and slightly deepened at apex. Pterostigma light yellowish brown.

Abdomen ( Fig. 7 ). T2–T4 black laterally, with broad yellow median stripe. T5 black with only indistinct narrow median stripe.A6 black with pair of divergent anal horns on dorsal apex. A7 and A8 black, greatly constricted at base.

Male genitalia ( Figs 9, 10 ). Genital bulb broad oval, mostly black with epandrium and hypandrium dark yellowish brown. Epandrium broad, deeply emarginated terminally and forming pair of finger-like, divergent processes laterally. Hypandrium split into pair of hypovavles. Hypovalve with row of long stout bristles along inner margin. Gonostylus shorter than gonocoxites, with well-developed basal lobe and subtriangular middle tooth. Paramere trifurcate: ventral branch extremely short and barb-like; median branch slightly shorter than dorsal branch and curved inward; dorsal branch slightly curved inward. Ventral valves of aedeagus membranous with rounded apex; dorsal valves sclerotized with subacute apex.

Female. Habitus ( Fig. 2 ) similar to males. Subgenital plate ( Fig. 11 ) broad, with distal 2/5 subtriangular and bearing long stout setae marginally. Medigynium ( Fig. 12 ) with basal portion of main plate broader than base of posterior arms; posterior arms slightly shorter than main plate.

Etymology. The specific epithet is dedicated to my friend Mr. Guo-Cong Huang, the first discoverer and collector of the new species. Noun in the genitive case.

Distribution. China: Yunnan (Gongshan) ( Fig. 54 ).
