sp. nov.

Panorpa caoweii Wang , sp. n.

( Fig. 4 View FIGURE 4 )

Etymology. The new species is named after Wei Cao, the collector of the type specimens. Noun in the genitive case.

Diagnosis. The new species is similar to Panorpa decolorata Chou &Wang, 1981 and Panorpa filina Chou & Wang, 1987 in the wing markings, but can be differentiated from P. decolorata by the bifurcated male parameres, and from P. filina by the males having unemarginated A6 and relatively straight dorsal branch of parameres.

Type series. CHINA: Guangxi: Holotype ♂ (CN20 Pa 00092), Mt. Mao’er ( Kitten Mountain ), Huilong Temple , 1580 m, 25°54’44’’ N, 110°27’57’’ E, 27.viii.2020, leg. Wei Cao; paratype 1♀ (CN20 Pa 00093), same data. GoogleMaps

Measurements. Male: AtL 11.2 mm, AbL 9.9 mm, BL 13.8 mm, FL 12.4 mm, FW 2.5 mm, HL 11.1 mm, HW 2.4 mm; Female: AbL 7.9 mm, BL 12.3 mm, FL 12.8 mm, FW 2.6 mm, HL 11.4 mm, HW 2.5 mm.

Description-male. Head. Vertex, occiput and rostrum yellowish brown, ocellar triangle black. Antennae scape yellowish brown, pedicel dark brown, flagellum black with 41–45 flagellomeres.

Thorax. Pronotum brown with anterior and posterior margins blackish, and three or four stout setae along each side of anterior margin. Meso- and metanotum brown laterally with pale median stripe. Pleura and legs light brown with distal tarsomeres dark brown.

Wings. Membrane hyaline and tinged with light yellowish brown, markings black. Pterostigma brown, veins dark brown except apical cross-veins pale. Forewing with apical band greatly reduced, vague, and detached with both anterior and posterior margins; pterostigmal band triangular and reduced at posterior half, with detached spot along hind margin as basal branch and lacking apical branch; basal band reduced to small spot above ending of CuP; marginal and basal spots absent; Sc extending slightly beyond middle of wing but not reaching pterostigma; R 1 bifurcated at pterostigmal region; Rs five-branched; R 2 –M 1 zigzagging at joints of apical cross-veins; 1A ending beyond level of ORs; and two cross-veins between 1A and 2A. Hindwings similar to forewings but with basal band absent.

Abdomen. T1–T5 dark brown, with pale, discontinuous median stripe extending from T1 to T3. Notal organ on posterior margin of T3 slightly developed and covering acute postnotal organ on T4. S1–S5 light brown, pleura pale. A6 blackish brown at basal half and gradually yellowing towards apex, cylindrical.A7 and A8 yellowish orange, A7 nearly cylindrical, A8 constricted basally and beveled apically.

Male genitalia. Genital bulb yellowish orange, long oval. Epandrium (T9) extending beyond middle of gonostylus, slightly tapering towards apex, with deep U-shaped terminal emargination and forming two parallel fingerlike processes. Cerci slender, clavate. Hypandrium (S9) Y-shaped and approximately 3/4 as long as gonocoxites, with long basal stalk and splitting into pair of hypovalves in distal half. Hypovalves narrow, divergent and tapering towards apex, with sparse long bristles along inner margin. Gonostyli shorter than half length of gonocoxites, with disc-shaped basal lobe and subtriangular median tooth. Parameres bifurcated, with both branches slender and acute at apex; ventral branch approximately half-length of dorsal branch and bending inward; dorsal branch slightly bending outward and extending to apex of gonocoxites. Ventral aedeagal valves membranous and rounded; dorsal processes slender, greatly elongated, nearly parallel, and tapering in to subacute apex in distal 1/3.

Description-female. Similar to males in general appearance, but with denser markings. In forewings, pterostigmal band with faded apical branch.

Female genitalia. Subgenital plate oblong with rounded apex and sparse long setae on distal margin. Medigynium slender, with main plate approximately half as long as axis; posterior arms short, acute and approximately 1/3 as long as main plate; apodemes of axis slightly divergent.

Distribution. CHINA: Guangxi (Mt. Mao’er) ( Fig. 2 View FIGURE 2 ).
