Type locality: Qinling Railway Station, Shaanxi, China; Wang & Hua, 2018: 374, figs 5-138-1-5-138-2. Diagnosis. This species can be readily recognized by the following characters: (1) wing markings well-developed, forewing apical band broad with one or two large inner hyaline spots; pterostigmal band with broad basal branch and thin apical branch; marginal spot large; broad basal band complete; basal spots large; (2) meso- and metanotum blackish brown, with prominent pale yellow mesal stripe; in males, (3) gonocoxites bearing 4-7 (usually 6) long setae along beveled inner apex ventrally; (4) parameres crossed mesally, twisted in S-shape, extended beyond gonocoxites; in females, (5) medigynium with main plate long, broad; a pair of lateral basal plates reaching two-thirds of main plate; axis extended beyond main plate for one-third of its length anteriorly. Material examined. CHINA - Shaanxi Prov. • 1♂ ( Holotype ); Fengxian , Qinling Railway Station ; 1600-2000 m a.s.l. ; 18 Aug. 1965 ; Io Chou & Jin-Sheng Lu leg. • 8♂♂ , 10♀♀ ( Paratypes ); same data as holotype • 1♀ ( Paratype ); Zhouzhi, Tianyu; 18-19 Aug. 1951 ; Io Chou leg. Measurements. Male: FL = 10.0-11.1 mm, FW = 3.0-3.2 mm; HL = 9.1-10.0 mm, HW = 2.9-3.1 mm. Female: FL = 10.5-11.5 mm, FW = 3.0-3.3 mm; HL = 9.6-10.5 mm, HW = 2.9-3.2 mm. Distribution. China: Shaanxi. Remarks. Panorpa neospinosa resembles P. sexspinosa , but differs from the latter in the conspicuous (cf. absent) basal spot.
