Parisoperla leigongshana Huo & Du, sp. nov.

Male: Forewing length ca. 11.2 mm, hindwing length 10.2 mm, body length 9.8 mm; general color brown (Fig. 11). Head brown, ocellar and frontoclypeal area dark brown. Antennae and palpi brown. Pronotum disc brown, rugosities present medially (Fig. 12A). Legs brown; wings hyaline, veins dark brown. Abdomen dark brownish and slightly sclerotized. Posterior margin of tergum 10 darkly sclerotized, recessed medially and rearward, extending as a process, with wide lateral grooves on surface, and perpendicular to tergum 10 posteriorly (Fig. 12B, Fig. 13). Vesicle reduced as a patch of bristles on posterior margin of sternum 8 (Fig. 12C). Paraprocts slender and lightly sclerotized.

Female: Unknown.

Egg: Unknown.

Nymph: Unknown.

Type material: Holotype: ♂, China, Guizhou Province, Leigongshan Nature Reserve, beside an unnamed road, 1198m, 26.3616N, 108.1650E, 2018-IV-22, leg. Du Yu-Zhou, Chen Zhi-Teng.

Etymology: The scientific name refers to the type locality.

Diagnosis: This species can be distinguished by the slender paraprocts and the shape of posteromedial margin of male tergum 10.

Remarks: This species is similar to P. kuankuoshuiensis, except for the longer process on male terminalia and smaller paraprocts (Fig. 14). It is also similar to P. oncocauda, but the sclerotized areas on terminalia are different in shape. The posteromedial margin of tergum 10 of the male of P. leigongshana is narrowed in dorsal view. Parisoperla oncocauda bears a process which is wider at posteromedial tergal margin and tapers distally.
