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 : 258-260

Panorpa jinfoshana Wang , sp. n.

( Fig. 12 )

Etymology. The new species is named after the type locality, Mt. Jinfo (Jinfo Shan). Noun in apposition.

Diagnosis. The new species closely resembles Panorpa guttata Navás, 1908 , but can be readily differentiated from the latter by the following characters: in males, 1) A6 with V-shaped emargination on dorsal apex, and forming pair of rounded lobes laterally (cf. narrow emargination and forming pair of truncated lobes laterally); 2) A6 with five small pointed teeth below rounded lobes on each lateral side (cf. only one); and in females, 3) medigynium with basally constricted basal plate (cf. with an oblong basal plate).

Type series. CHINA: Chongqing: Nanchuan: Holotype ♂ (CN19Pa00239), Mt. Jinfo, Wind Blowing Ridge , 2220 m, 29°01’60’’ N 107°11’30’’ E, 19.viii.2019, leg. Ri-Xin JIANG; paratypes 5♂ 12♀ (CN19Pa00240–CN-19Pa00256), same data.

Measurements. Male: AtL 9.8–10.2 mm, AbL 6.0- 6.5 mm, BL 9.0–10.0 mm, FL 10.8–11.2 mm, FW 2.3–2.5 mm, HL 10.0–11.0 mm, HW 2.2–2.4 mm; Female: AbL 7.2–7.5 mm, BL 9.0–10.0 mm, FL 11.0– 11.6 mm, FW 2.4–2.6 mm, HL 10.0– 10.3 mm, HW 2.3–2.5 mm.

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

Wings. Membrane hyaline, slightly tinged with yellowish brown, with greatly reduced brown markings. Pterostigma yellow and conspicuous. Forewing markings greatly reduced and scattered; only apical and pterostigmal bands present; 1A ending beyond level of ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings but nearly devoid of markings.

Abdomen. T1–T5 yellowish brown and slightly deepened laterally. A6 yellowish brown, cylindrical, with deep V-shaped emargination on dorsal apex, and forming pair of broad triangular lobes laterally, and five small pointed teeth (dorsal one largest) below lobes on each lateral side. 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, tapering towards apex, with U-shaped terminal emargination and forming pair of short finger-like processes. Hypandrium Y-shaped and approximately 7/8 as long as gonocoxites, with basal stalk approximately 1/3 as long as hypovalves. Hypovalves narrow, divergent in basal half and nearly parallel in distal half, with sparse long bristles along inner margin. Gonocoxites bearing dense long stout setae on inner apex ventrally. Gonostyli shorter than half length of gonocoxites, with broad earlobe-shaped basal lobe and rounded median tooth, and row of long stout setae on basal half of ventral surface. Parameres furcated into two slender branches and covered with numerous microtrichia on inner margin of each branch; ventral branch long, stout and pointed apically; dorsal branch approximately 4/5 as long as ventral branch. Ventral aedeagal valves membranous and covered with numerous microtrichia; dorsal processes stout, greatly elongated, nearly parallel, and with greatly constricted apex.

Description-female. Similar to males in general appearance except for denser wing markings and darker terga.

Female genitalia. Subgenital plate oval with rounded apex, and sparse long setae on distal margin. Medigynium with basally constricted basal plate; main plate approximately 1/2 as long as axis; posterior arms short and stout; apodemes greatly divergent basally.

Distribution. CHINA: Chongqing: Nanchuan (Mt. Jinfo) ( Fig. 2 ).

Notes. In Mt. Jinfo, this species emerges later (August) than its coinhabiting species Panorpa liaoi Zhou & Zhou, 2007 and Panorpa jiangrixini Wang , sp. n. (June to July).
