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 : 265-266

Panorpa substricta sp. n.

( Fig. 17 )

Etymology. The specific epithet is the Latin substricta (contracted, narrow, and small), referring to the small lobes on the dorsal apex of male A6. Adjective.

Diagnosis. The new species greatly resembles Panorpa filina Chou & Wang, 1987 and Panorpa caoweii Wang , sp. n. in the general appearance (especially, wing markings), but can be differentiated from the latter two by the males bearing pair of very small lobes on dorsal apex of A6, and the peculiar shape of the female medigynium.

Type series. CHINA: Guizhou: Holotype ♂ (CN17Pa00035), Mt. Leigong , 1700 m, 26°22’46’’ N 108°11’38’’ E, 04.ix.2017, leg. Ming-Zhi Zhao; paratypes 3♂ 1♀ (CN17Pa00036– CN17Pa00039), same data.

Measurements. Male: AtL 11.0 mm, AbL 8.8 mm, BL 12.5 mm, FL 13.0 mm, FW 2.5 mm, HL 12.0 mm, HW 2.4 mm; Female: AbL 9.5 mm, BL 13.8 mm, FL 13.3 mm, FW 2.6 mm, HL 12.2 mm, HW 2.5 mm.

Description-male. Head. Vertex, occiput and rostrum yellowish brown, ocellar triangle black.

Wings. Membrane hyaline and tinged with yellowish brown, markings black. Forewing with apical band broad and enclosing two large hyaline spots along apical cross-veins; pterostigmal band triangular with detached basal and apical branches posteriorly; marginal spot small and below R 1; basal band represented by wide spot at ending of 1A; basal spot at inner side of ending of 2A; 1A ending beyond level of ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings but with more reduced markings.

Abdomen. T1–T5 dark brown, with pale, discontinuous median stripe extending from T1 to T4. A6 blackish brown, cylindrical, with shallow V-shaped emargination on dorsal apex and forming pair of very small, subtriangular lobes. A7 and A8 yellowish orange, A7 nearly cylindrical, greatly humped on dorsal apex; A8 constricted basally and beveled apically.

Male genitalia. Genital bulb yellowish brown, 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 7/8 as long as gonocoxites, with long basal stalk and splitting into pair of hypovalves in distal half. Hypovalves narrow, parallel, with sparse long bristles along inner margin. Gonostyli approximately half as long as gonocoxites, with disc-shaped basal lobe and subtriangular median tooth. Parameres bifurcated, with both branches slender and pointed at apex; ventral branch very short, approximately 1/5 as long as dorsal branch, greatly curved inward and hook-like; dorsal branch stout and straight. Ventral aedeagal valves membranous, greatly elongated and extending beyond apex of parameres; dorsal processes greatly elongated, broad foliate with apex beveled.

Description-female. Similar to males in general appearance, but with denser markings.

Female genitalia. Subgenital plate oval with slightly truncated apex and sparse long setae on distal margin. Medigynium with main plate approximately 2/3 as long as axis; posterior arms slender, acute and approximately half as long as main plate; apodemes of axis stout and greatly divergent basally.

Distribution. CHINA: Guizhou (Mt. Leigong) ( Fig. 2 ).
