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.

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

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).

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.

The new species inhabits dense herbaceous ground cover aside an irrigation canal in a suburban field (Fig. 1A) 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) in spring (19.iv.2018), likely indicating the bivoltinism of this species.

The new species is superficially similar to Panorpa waongkehzengi Navás, 1935 from Jiangxi and P. jinhuaensis sp. nov. in general appearance, but can be readily differentiated from the latter two by the presence (cf. absence) of a black pattern on the occiput, and a greatly shortened (cf. long) axis in the female medigynium.

China, Anhui (Yuexi and Huoshan Counties).

Two male-unknown species, Panorpa pusilla Cheng, 1949 from Shaanxi and Panorpa pieli Cheng, 1957 from Jiangxi, are probably related to P. menqiuleii sp. nov. by the unbranched R₂ in both fore- and hindwings, and the twisted posterior arms and short axis in female medigynium. The black pattern on the occiput, however, can readily distinguish P. menqiuleii sp. nov. from these two species.

China, Zhejiang: Deqing County (Mount Mogan).

Panorpa mokansana Cheng, 1957 and Panorpa wrightae Cheng, 1957 were described from the same locality, Mount Mogan, based on a single male (19.ix.1927) and a single female (28.ix.1927), respectively (Cheng 1957a). The holotypes of these two nominal species are deposited in the Collection of California Academy of Sciences, San Francisco, California. According to Cheng’s descriptions, the female of P. wrightae resembles the male of P. mokansana in wing markings but only differs from the latter in the body color (dull brown vs. mostly reddish brown). During our recent expedition in Zhejiang Province, a number of new materials were collected from the type locality. The males have been readily determined to be P. mokansana, and the females conform to Cheng’s description and illustration of P. wrightae. Because females are essential for an insect species, it is reasonable for us to consider that P. mokansana and P. wrightae are very likely conspecific. Therefore, P. wrightae is treated as a junior subjective synonym of P. mokansana herein.
