Panorpa jinhuaensis sp. nov. Figures 1 View Figure 1 , 2 View Figure 2

Type material.

Holotype: ♂ (NWAU), CHINA: Zhejiang Province, Jinhua City [金华市], southern slope of Mount Jinhua [金华山], Zhizhe (Wise Man) Temple [智者寺] (29°10'03"N, 119°37'21"E, 104 m), 2.x.2018, leg. Ji-Shen Wang; Paratypes: 20♂13♀ (NWAU), same data as for the holotype.

Etymology.

The specific name refers to the type locality, Jinhua City.

Diagnosis.

This new species is superficially similar to Panorpa waongkehzengi Navás, 1935 from Jiangxi, but can be readily differentiated from the latter by: in males, 1) apex of epandrium broadly rounded (cf. abruptly narrowed); 2) inner margin of hypovalve straight (cf. with an inner process); 3) paramere long and exceeding apex of gonocoxites (cf. short and not exceeding apex of gonocoxites); 4) apical portion of paramere spiral (cf. straight); 5) parameres crossed subbasally (cf. not crossed); and in females, 6) main plate of medigynium moderately developed (cf. poorly developed).

Measurements.

Male FL 10.2‒10.8 mm, FW 2.6‒2.8 mm; HL 9.0‒9.5 mm, HW 2.4‒2.6 mm. Female FL 11.0‒11.8 mm, FW 3.0‒3.2 mm; HL 10.0‒10.6 mm, HW 2.8‒3.0 mm.

Description-male.

Head ( Fig. 2C View Figure 2 ). Vertex, occiput and frons orange-yellow, with lateral margins of occiput slightly darkened. Black spot enclosing ocellar triangle and slightly spreading anteriorly. Compound eyes black, narrower than base of rostrum. Rostrum orange-yellow, stout, sparsely covered with short setae, with its length approximately 2.6 times as long as basal width. Labrum dark yellowish brown. Maxillary palp with basal four segments dark yellowish brown and distal segment black. Scape yellowish brown with distal margin dark brown; pedicel and flagellum black; flagellomeres 34‒36.

Thorax ( Fig. 2D View Figure 2 ). Pronotum unevenly orange-yellow, with 10‒12 stout setae along anterior margin. Meso- and metanotum orange-yellow and sparsely covered with short setae; scutellar arms slightly deepened. Pleura and legs orange-yellow, with distal tarsomere blackish.

Wings ( Fig. 1D View Figure 1 , 2A View Figure 2 ). Membrane subtranslucent, strongly tinged with yellow and fading toward apex. Markings black. Veins yellowish brown except apical crossveins pale white. Pterostigma orange-yellow and distinct. Forewing apical band broad, usually with 1‒3 hyaline windows enclosing crossveins between R3 and M1, and a separated spot at ending of M2 posteriorly; apical branch of pterostigmal band variable: intact ( Fig. 1D View Figure 1 ) or detached with pterostigmal band and greatly elongated anteriorly ( Fig. 2A View Figure 2 ); basal branch of pterostigmal band intact and slightly broader than apical branch; marginal spot C-shaped; basal band split into two large spots; an additional transverse band extending from ending of 2A to CuA; basal spot shifted posteriorly and along anal margin; an additional small spot anterior to 3A; R2 bifurcated. Hindwing similar to forewings but bearing relatively reduced markings: basal band split into a large spot along posterior margin, and a small indistinct spot slightly distal to ORs; spots and band proximal to basal band absent.

Abdomen ( Fig. 2A, D, E View Figure 2 ). Terga II‒V orange-yellow and slightly darkened at lateral margins, sparsely covered with black short setae; corresponding sterna lighter. Notal organ on posterior margin of T3 slightly prolonged posteriorly with truncated apex, bearing dense black setae on hind margin, and covering acute postnotal organ on anterior portion of T4. A6‒A8 orange-yellow, cylindrical. A6 as long as A5 and devoid of anal horns. A7 slightly shorter and narrower than A6. A8 nearly as long as A7, slightly enlarged posteriorly with a beveled apex.

Genital bulb ( Fig. 2F, G View Figure 2 ) long oval, mostly orange-yellow except distal third of gonostyli blackish. Epandrium long and broad, evenly tapering toward rounded apex bearing dense long setae. Cerci clavate, orange-yellow in basal half and black in distal half. Hypandrium with short broad stalk and a pair of longer hypovalves; each hypovalve tapering toward apex, and bearing long stout setae along inner margin. Gonocoxites stout, approximately 1.6 times as long as gonostyli; gonostyli slightly curved on outer margin, and with a rounded median tooth and a large bowl-shaped basal process on inner margin. Paramere ( Fig. 2H View Figure 2 ) slender, with greatly expanded stalk basally; connected to aedeagus through curved bridge-like process dorsally; and extending slightly beyond apex of gonocoxites with spiral and acute apex. Two parameres crossed basal to ventral aedeagal valves. Dorsal aedeagal processes greatly elongated posteriorly with slightly enlarged and beveled apex, and bearing a row of short setae along basal third of inner margin; lateral processes short and stout.

Description-female.

Similar to males except relatively denser wing markings. In fore- and hindwings, pterostigmal band with apical branch intact, scattered into 1‒3 small spots anteriorly ( Figs 1B View Figure 1 , 2B View Figure 2 ) or slender and extending to anterior margin, forming an H-shaped pattern ( Fig. 1E View Figure 1 ).

Female genitalia ( Fig. 2I, J View Figure 2 ). Subgenital plate oval, slightly tapering toward shallowly emarginate apex, and bearing long stout setae marginally. Medigynium with moderately developed main plate; posterior arms slightly shorter than main plate and twisted ventrally in distal half; axis longer than posterior arms, with apodemes extending beyond main plate and slightly divergent anteriorly; posterior apex of axis subtriangular and slightly extending beyond main plate.

Distribution.

China, Zhejiang (Jinhua).

Remarks.

The new species inhabits dense herbaceous ground cover aside an irrigation canal in a suburban field ( Fig. 1A View Figure 1 ) with a surprisingly low elevation of 104 m (most Panorpa species in eastern China prefer higher mountainous regions above 600 m). The species is sympatric with another autumnal species, Panorpa tetrazonia Navás, 1935, which can be differentiated from the former by its larger body size (FL 12.0-13.0 mm) and brown body color. Apparently, P. jinhuaensis sp. nov. represents the dominant species at the locality, because only three males and two females of the latter were collected on the same day (2.x.2018). In addition, a female adult of P. jinhuaensis sp. nov. was photographed ( Fig. 1B View Figure 1 ) in spring (19.iv.2018), likely indicating the bivoltinism of this species.
