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 : 255-257

Panorpa huangguiqiangi Wang , sp. n.

( Fig. 10 )

Etymology. The new species is named after Gui-Qiang Huang, collector of the type specimens. Noun in the genitive case.

Diagnosis. The new species is peculiar by the combination of the following characters: 1) wings markings greatly reduced and scattered, with inner portion of apical band and pterostigmal band forming two vertically inversed Y-shaped patterns; in males, 2) A6 with shallow arcuate emargination and forming pair of broad triangular lobes laterally at dorsal apex; 3) parameres bifurcated with slender ventral and dorsal branches; and in females, 4) medigynium with main plate broadest at middle and greatly curled marginally.

Type series. CHINA: Guizhou: Liupanshui: Holotype ♂ (CN20Pa00114), Yushe National Forest Park, 2260 m, 26°27’32’’ N 104°48’08’’ E, 01.ix.2020, leg. Gui-Qiang Huang; paratypes 2♀ (CN20Pa00115, CN20Pa00116), same data.

Measurements. Male: AtL 9.3 mm, AbL 7.0 mm, BL 9.2 mm, FL 9.6 mm, FW 2.2 mm, HL 8.5 mm, HW 2.1 mm; Female: AbL 6.8 mm, BL 10.2 mm, FL 10.6 mm, FW 2.6 mm, HL 9.2 mm, HW 2.5 mm.

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

Wings. Membrane hyaline, tinged with yellowish brown, markings dark brown. Pterostigma yellow and conspicuous. Forewing markings greatly reduced to spots; apical band splitting into two longitudinal parts; inner portion of apical band and pterostigmal band forming two vertically inversed Y-shaped patterns; other markings absent; 1A ending slightly beyond level of ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings with more reduced markings.

Abdomen. T1–T5 yellowish brown, with yellow, continuous median stripe extending from T1 to T5. A6 yellowish brown, cylindrical, with shallow arcuate emargination on dorsal apex, and forming pair of broad triangular lobes laterally. 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 two short finger-like processes. Hypandrium Y-shaped and approximately 2/3 as long as gonocoxites, with basal stalk approximately half as long as hypovalves. Hypovalves narrow, divergent in basal half and nearly parallel in distal half, with sparse long bristles along inner margin. Gonostyli shorter than half length of gonocoxites, with broad earlobe-shaped basal lobe and rounded median tooth. Parameres furcated into two slender branches and covered with numerous microtrichia on inner margin of each branch; ventral branch approximately 4/5 as long as dorsal branch, and stout, curved and pointed apically; dorsal branch similar and crossed subapically. Ventral aedeagal valves membranous, elongated, and covered with numerous microtrichia; dorsal processes stout, greatly elongated, nearly parallel but slightly divergent apically, and with shallow emargination at apex.

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

Female genitalia. Subgenital plate subtrapezoidal with truncated apex, and sparse long setae on distal margin. Medigynium with main plate approximately 3/4 as long as axis, broadest at middle, and greatly curled marginally; posterior arms very short and stout; apodemes divergent basally.

Distribution. CHINA: Guizhou: Liupanshui (Yushe) ( Fig. 2 ).

Notes. This species coinhabits with Panorpa latiloba Wang , sp. n. in the type locality.
