Panorpa jinchuana Hua, Sun & Li, 2001: 121, fig. 1A-B. Type locality: Jinchuan, Sichuan, China; Wang & Hua, 2018: 355, figs 5-129-1-5-129-2.

Diagnosis.

This species can be readily recognized by the following characters: (1) wing markings well-developed, forewing apical band with two inner hyaline spots; pterostigmal band complete, with broad basal branch and thinly connected or detached apical branch; marginal spot large; basal band split into two spots; basal spot greatly reduced (Fig. 17A-B ); (2) meso- and metanotum black, with broad pale mesal stripe (Fig. 17A-B ); in males, (3) gonocoxites with cluster of long setae along slightly oblique inner apex ventrally (Fig. 17E ); (4) parameres crossed mesally, twisted in S-shape (Fig. 17G ); in females, (5) main plate of medigynium three times as long as posterior arms; axis extended beyond main plate for half of its length anteriorly (Fig. 17I-J ).
