Wang, Ji-Shen & Gong, You-Jing, 2021, Taxonomy of the Panorpaguttata group (Mecoptera: Panorpidae), withdescriptions of fourteen new species from China, Zootaxa 4981 (2), pp. 241-274 : 266-267

Panorpa xiaofeng Wang & Gong , sp. n.

( Fig. 18 )

Etymology. The new species is named after Feng Xiao, one of three protagonists in the famous Chinese novel Demi-Gods and Semi-Devils. Noun in apposition.

Diagnosis. The new species superficially resembles Panorpa kunmingensis Fu & Hua, 2009 in general appearance, especially the wing markings reduced to several spots, and the triangular lobes in male A6. However, it can be readily differentiated by the following characters: 1) male hypovalves divergent terminally (cf. slightly convergent); 2) female axis of medigynium approximately twice as long as main plate (cf. approximately three times as long as the latter).

Type series. CHINA: Yunnan: Yunlong : Holotype ♂ (CN20Pa00173), burned area near the Sky Lake , 2740 m, 25°51’1’’ N 99°14’8’’ E, 12–28.ix.2020, leg. You-Jing Gong by Malaise Trap ; Paratypes 2♂ 12♀ (CN20Pa00174CN20Pa00187), same data .

Measurements. Male: AtL 9.5–9.9 mm, AbL 8.4–8.8 mm, BL 11.5–12.0 mm, FL 10.0– 10.8 mm, FW 2.5–2.6 mm, HL 9.0– 9.6 mm, HW 2.3–2.4 mm; Female: AbL 7.0–8.0 mm, BL 10.0– 11.2 mm, FL 10.8–11.5 mm, FW 2.5–2.6 mm, HL 9.0–10.0 mm, HW 2.4–2.5 mm.

Description-male. Head. Vertex, occiput and rostrum yellowish brown. Ocellar triangle enclosed by dark spot.

Wings. Membrane hyaline, slightly tinged with grayish brown, with apical and pterostigmal bands greatly reduced to several spots. Forewing 1A ending almost same level of ORs; and usually, two cross-veins between 1A and 2A (one in the left forewing, and none in the rightwing of holotype). Hindwings similar to forewings.

Abdomen. T1–T5 yellowish brown. A6 deeply emarginated in V-shape and forming pair of rounded triangular lobes. A7 and A8 yellowish brown, A7 nearly cylindrical and greatly humped on dorsal apex, A8 constricted basally and beveled apically.

Male genitalia. Genital bulb yellowish brown, 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 9/10 as long as gonocoxites, with narrow basal stalk approximately as long as hypovalves. Hypovalves narrow, divergent, with sparse long bristles along inner margin. Gonostyli approximately half as long as gonocoxites, greatly incurvated along outer margin, with disc-shaped basal lobe and subtriangular median tooth. Parameres bifurcated, with both branches acute at apex, and covered with numerous microtrichia; ventral branch approximately 2/5 as long as dorsal branch; dorsal branch greatly elongated and bending outwards apically. Ventral aedeagal valves membranous and rounded; dorsal processes stout, greatly elongated, nearly parallel, and with finger-like projection apically.

Description-female. Similar to males but with denser wing markings.

Female genitalia. Subgenital plate oblong with slightly emarginated apex and sparse long setae on distal margin. Medigynium with broad main plate approximately half as long as axis; posterior arms slender and slightly longer than main plate; apodemes of axis greatly divergent basally.

Distribution. CHINA: Yunnan: Yunlong ( Fig. 2 ).
