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 : 260

Panorpa latiloba Wang , sp. n.

( Fig. 13 )

Etymology. The specific epithet is combined from the Latin latus (broad) and lobus (lobe), referring to the lobes on dorsal apex of male A6 being broad. Compound noun in apposition.

Diagnosis. The new species closely resembles Panorpa jinfoshana Wang , sp. n. in general appearance, but can be readily differentiated from the latter by the following characters: in males, 1) A6 with lobes on dorsal apex very long and broad, extending beyond middle of A7 (cf. shorter and narrower, approximately extending to middle of A7); 2) A6 with five same sized pointed teeth below rounded lobes on each lateral side (cf. dorsal one largest); 3) parameres with ventral branch foliate, at least three times as wide as dorsal branch, and two times as long as dorsal branch (cf. ventral branch thinner and dorsal branch longer); and in females, 4) medigynium with posterior arms half as long as main plate and greatly curved inwards (cf. approximately 1/3 as long as main plate and slightly curved inwards).

Type series. CHINA: Guizhou: Liupanshui: Holotype ♂ (CN20Pa00120), Yushe National Forest Park, 2260 m, 26°27’32’’ N 104°48’08’’ E, 01.ix.2020, leg. Gui-Qiang Huang; paratypes 6♂ 12♀ (CN20Pa00121–CN20Pa00138), same data.

Measurements. Male: AtL 8.0– 9.2 mm, AbL 6.0– 7.6 mm, BL 8.6–9.4 mm, FL 10.0– 10.6 mm, FW 2.3–2.4 mm, HL 9.0– 9.4 mm, HW 2.2–2.3 mm; Female: AbL 6.2–7.0 mm, BL 8.8–9.4 mm, FL 10.5–11.6 mm, FW 2.4–2.5 mm, HL 9.2–10.3 mm, HW 2.3–2.4 mm.

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

Wings. Membrane hyaline, slightly tinged with yellowish brown, and devoid of markings. Pterostigma yellow and conspicuous. Forewing 1A ending beyond level of ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings.

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 very long and 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 finger-like processes. Hypandrium Y-shaped and approximately as long as gonocoxites, with basal stalk approximately 1/4 as long as hypovalves. Hypovalves narrow, broadest at middle, divergent, with sparse long bristles along inner margin. Gonostyli approximately half as long as gonocoxites, with an earlobe-shaped basal lobe and rounded median tooth, and row of long stout setae on basal half of ventral surface. Parameres bifurcated and covered with numerous microtrichia on inner margin of each branch; ventral branch long, slightly foliate, and three times as wide as dorsal branch; dorsal branch slender and approximately half as long as ventral branch. Ventral aedeagal valves membranous and covered with numerous microtrichia; dorsal processes stout, greatly elongated, nearly parallel, and with beveled apex.

Description-female. Similar to males in general appearance except for 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, and approximately half as long as main plate; apodemes greatly divergent basally.

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