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 : 249-250

Panorpa duanyu Wang & Gong , sp. n.

( Fig. 5 )

Etymology. The new species is named after Yu Duan, the 16th emperor of the Kingdom of Dali between 1108 and 1147. He is also one of the three protagonists in the famous Chinese novel Demi-Gods and Semi-Devils. Noun in apposition.

Diagnosis. The new species can be readily recognized by the following combination of characters: 1) wings devoid of markings except greatly reduced apical and pterostigmal bands; in males, 2) A6–A7 black; and 3) parameres crossed.

Type series. CHINA: Yunnan: Yunlong : Holotype ♂ (CN20Pa00163), burned area near the Sky Lake , 2740 m, 25°51’5’’ N 99°14’11’’ E, 12–28.ix.2020, leg. You-Jing Gong by Malaise Trap ; Paratypes 2♂ 7♀ (CN20Pa00164CN20Pa00172), same data .

Measurements. Male: AtL 8.0– 8.2 mm, AbL 6.0– 6.3 mm, BL 8.8–9.0 mm, FL 9.2–9.3 mm, FW 2.1–2.2 mm, HL 8.0– 8.2 mm, HW 1.9–2.0 mm; Female: AbL 4.8–5.0 mm, BL 7.0– 7.3 mm, FL 10.5–11.2 mm, FW 2.2–2.4 mm, HL 9.2–10.0 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, with greatly reduced apical and pterostigmal bands. 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 black. A6 black, cylindrical. A7 and A8 black and slightly yellowing towards apex, A7 cylindrical, A8 constricted basally and beveled apically.

Male genitalia. Genital bulb mostly yellowish brown and oval, with distal portion of gonostyli black. Epandrium extending beyond middle of gonostylus, tapering towards apex, with U-shaped terminal emargination and forming two finger-like processes. Hypandrium Y-shaped and approximately 3/5 as long as gonocoxites, with basal stalk approximately half as long as hypovalves. Hypovalves slender, divergent, with sparse long bristles along inner margin. Gonostyli approximately half as long as gonocoxites, with broad earlobe-shaped basal lobe and rounded median tooth. Parameres slender and covered with numerous microtrichia on inner margin of each branch; two parameres crossed at middle portion, with distal portions approximately parallel and directing caudad. Ventral aedeagal valves membranous and covered with numerous microtrichia; dorsal processes stout, greatly elongated, nearly parallel, neck-like in basal half and subacute in distal half.

Description-female. Similar to males in general appearance.

Female genitalia. Subgenital plate oval with slightly pointed apex, and sparse long setae on distal margin. Medigynium with broad main plate approximately 3/5 as long as axis; posterior arms short and thin, and approximately 1/3 as long as main plate; apodemes greatly divergent basally.

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

Notes. This species coinhabits with Panorpa xiaofeng Wang & Gong , sp. n. and Panorpa xuzhu Wang & Gong , sp. n. in the type locality.
