Etymology.
The specific name is dedicated to Ri-Xin Jiang, for donating the
type
specimens. Noun in the genitive case.
Diagnosis.
The new species is peculiar by the combination of the following characters: 1) wings devoid of markings; in males, 2) A6 with very shallow arcuate emargination on dorsal apex; 3) distal half of hypovalves approximately half as wide as basal half; 4) parameres trifurcated with basal branch short, stout and hook-like; and in females, 5) medigynium with axis entirely concealed in main plate.

Description-male.
Head
. Vertex, occiput and ocellar triangle shining black. Rostrum mostly shining black with yellowish lateral margin. Antennae with scape dark brown, pedicel black, and flagellum dark brown; flagellum with 40 flagellomeres.
Thorax
. Pronotum mostly black with yellowish median spot on posterior margin, and six to eight stout setae along each side of anterior margin. Meso- and metanotum mostly dark brown with discontinuous yellow median stripe forming two bottle-shaped patterns. Pleura and legs brown with distal tarsomeres dark brown.
Wings
. Broad in shape. Membrane hyaline, tinged with light grayish brown, devoid of markings. Forewing 1A ending slightly beyond level of ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings with more reduced markings.
Abdomen
. T1–T5 dark brown to black. A6 dark brown at base and gradually yellowing towards apex, cylindrical, with shallow arcuate emargination on dorsal apex, and forming pair of inconspicuous subtriangular lobes laterally. A7 and A8 yellowish brown, A7 nearly cylindrical and slightly humped on dorsal apex, A8 constricted basally and beveled apically.
Male genitalia
. Genital bulb yellowish brown, oval. Epandrium broad, not exceeding apex of gonocoxites, with U-shaped terminal emargination and forming two short stout processes. Hypandrium Y-shaped and approximately 4/5 as long as gonocoxites, with basal stalk approximately 1/3 as long as hypovalves. Hypovalves narrow, nearly parallel, with distal half approximately half as wide as basal half, and long stout bristles on inner margin of distal half. Gonocoxites with dense stout setae on inner apex ventrally. Gonostyli shorter than half length of gonocoxites, with broad rounded basal lobe and subtriangular median tooth, and covered with numerous long stout setae on basal half of ventral surface. Parameres trifurcated and covered with numerous microtrichia on each branch; basal branch stout and shortest, stretching towards base of genital bulb, greatly curved outward and hook-shaped, with apexes exposing from lateral margin of hypovalves; ventral and dorsal branches slender and straight; ventral branch nearly half as long as dorsal branch, both tapering towards pointed apexes. Ventral aedeagal valves membranous, elongated, bottle-shaped, extending to same level of parameres apically, and covered with numerous long microtrichia; dorsal processes stout, greatly elongated, slightly divergent apically.
Description-female.
Similar to males in general appearance.
Female genitalia
. Subgenital plate oblong with rounded apex, and sparse long setae marginally. Medigynium with main plate broad and sub-oval; axis entirely concealed in main plate with slightly divergent apodemes; posterior arms thin and approximately 1/4 as long as main plate.
