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 : 261-262

Panorpa nanzhao Wang , sp. n.

( Figs 14 & 15 )

Etymology. The new species is named after the Nanzhao Kingdom (738–937 AD), centered in the modern Yunnan Province with Taihe (modern-day Taihe village, a few miles south of Dali) as its capital. Noun in apposition.

Diagnosis. The new species is similar to Panorpa liaoi Zhou & Zhou, 2007 in the nearly marking-less wings and the black male A6–A8, but can be differentiated from the latter by the following characters: in males, 1) hypandrium approximately 1/3 as long as gonocoxites (cf. approximately as long as gonocoxites); 2) parameres bifurcated (cf. trifurcated); 3) dorsal aedeagal process foliate with tapering apex (cf. with beveled apex); and in females, 4) medigynium with broad main plate nearly parallel on lateral margins (cf. with narrower main plate incurvated on lateral margins).

Type series. CHINA: Yunnan: Dali: Holotype ♂ (CN20Pa00139), Mt. Cangshan, eastern slope of the Orchid Peak , 2550 m, 25°43’30’’ N 100°06’25’’ E, 11.viii.2020, leg. Ji-Shen Wang; paratypes 9♂ 3♀ (CN20Pa00140–CN-20Pa00151), same data.

Measurements. Male: AtL 10.5–10.8 mm, AbL 6.4–7.0 mm, BL 10.0– 11.2 mm, FL 10.8–11.8 mm, FW 2.3–2.5 mm, HL 9.6–10.5 mm, HW 2.3–2.4 mm; Female: AbL 5.0–6.0 mm, BL 8.2–9.0 mm, FL 10.9–11.8 mm, FW 2.4–2.5 mm, HL 9.9–10.4 mm, HW 2.3–2.4 mm.

Description-male. Head. Vertex and occiput yellow, rostrum brown. Ocellar triangle black.

Wings. Membrane hyaline, slightly tinged with grayish brown, and with only minute spot as pterostigmal band. Forewing 1A ending almost same level of ORs; and two cross-veins between 1A and 2A. 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 yellowish brown, oval. 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 2/3 as long as gonocoxites, with basal stalk approximately 1/4 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 bifurcated and covered with numerous microtrichia on inner margin of each branch; ventral branch very short and hook-like; dorsal branch slender, slightly convergent apically, arcuate in basal half and straight in distal half. Ventral aedeagal valves membranous and covered with numerous microtrichia; dorsal processes stout, greatly elongated, nearly parallel, necklike in basal half and foliate in distal half, and slightly curved inward apically.

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: Dali (Mt. Cangshan) ( Fig. 2 ).
