(Fig. 19)
Etymology. The new species is named after Xuzhu, one of three protagonists in the famous Chinese novel DemiGods and Semi-Devils. Noun in apposition.
Diagnosis. The new species is peculiar in the Panorpa guttata group by the combination of the following characters: 1) body mostly yellow; 2) wings devoid of markings or with greatly reduced pterostigmal and apical bands; in males, 3) A6 nearly truncated at apex and lacking lobes; 4) dorsal processes slender and approximately as wide as parameres except enlarged distal portion; and in females, 5) axis of medigynium extremely long, slightly longer than twice the length of main plate.
Type series. CHINA: Yunnan: Yunlong: Holotype ♂ (CN20Pa00188), burned area near the Sky Lake, 2813 m, 25°51’7’’ N 99°14’9’’ E, 12–28.ix.2020, leg. You-Jing Gong by Malaise Trap; Paratypes 1♂ 7♀ (CN20Pa00189CN20Pa00196), same data.
Measurements. Male: AtL 9.0– 9.4 mm, AbL 8.4–8.6 mm, BL 11.5–11.8 mm, FL 9.6–10.0 mm, FW 2.1–2.2 mm, HL 8.5–9.0 mm, HW 2.0– 2.1 mm; Female: AbL 8.0–9.0 mm, BL 11.0–13.0 mm, FL 10.8–11.3 mm, FW 2.2–2.4 mm, HL 9.5–10.2 mm, HW 2.1–2.3 mm.
Description-male. Head. Vertex, occiput and rostrum yellowish brown. Ocellar triangle enclosed by dark spot.
Wings. Membrane hyaline, slightly tinged with grayish brown and devoid of markings. Forewing 1A ending almost same level of ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings.
Abdomen. T1–T5 yellow. A6 yellow, cylindrical, nearly truncated at apex and lacking lobes. A7 and A8 yellow, A7 nearly cylindrical and slightly beveled at dorsal apex, A8 constricted basally and greatly beveled apically.
Male genitalia. Genital bulb yellow, long oval. Epandrium extending beyond middle of gonostylus, slightly tapering towards apex, with deep U-shaped terminal emargination and forming two parallel finger-like processes. Hypandrium Y-shaped and approximately 7/10 as long as gonocoxites, with long basal stalk approximately as long as hypovalves. Hypovalves narrow, divergent, with sparse long bristles along inner margin. Gonostyli shorter than half length of gonocoxites, slightly incurvated on outer margin, with disc-shaped basal lobe and subtriangular median tooth. Parameres bifurcated with both branches slender and bearing numerous microtrichia subapically; ventral branch approximately 4/5 as long as dorsal branch, and greatly bending outwards apically; dorsal branch relatively straight. Ventral aedeagal valves membranous, rounded, and covered with numerous microtrichia; dorsal processes slender, greatly elongated and enlarged towards apex, and with longitudinal groove.
Description-female. Similar to males in general appearance, but with greatly reduced pterostigmal and apical bands in forewings.
Female genitalia. Subgenital plate oblong with slightly emarginated apex and sparse long setae on distal margin. Medigynium slender, with main plate broadest at basal 2/5 and approximately 1/3 as long as axis; posterior arms slender and approximately 2/3 as long as main plate; apodemes of axis greatly divergent at base.
Distribution. CHINA: Yunnan: Yunlong (Fig. 2).
