Figures 8–9

Description. Male. Body medium. Head and pronotum as other species of the genus. Fore coxae with 1 spine; femora with 1 short ventral spine on internal margin; tibiae with 1 internal and 2 external spines ventrally, apices with 1 pair of spines on ventral surface. Middle femora with 1 pair of apical spines on ventral surface; tibiae dorsally with 2 pairs of spines, ventral surface with 1 internal and 3 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind femora with 1 short ventral spine on internal margin; tibiae dorsally with 17 internal spines, 18 external spines and 1 pair of small subapical spines, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 3–5 small spines and 1 apical spine on dorsal surface along the midline (Fig. 8C).

Epiproct slightly longer than wide, basal margin semicircular, dorsal surface faintly concave, the surrounding margins raised; posterior margin almost straight (Fig. 8E). Cerci slender, conical, apices acute (Fig. 8D). Subgenital plate transverse, posterior margin widely arched with indistinct median notch; styli cylindrical, its apices obtuse, inserted on posterolateral area of the plate (Fig. 8E).

Female. Posterior margin of tenth abdominal tergite with an arched concavity in middle (Fig. 9E). Epiproct longer than wide, dorsal surface with median furrow, apex rounded (Fig. 9E). Cerci slender. Subgenital plate semicircular, lateral margins of basal half convex, posterior margin rounded with 1 small angle in the middle (Fig. 9F). Ovipositor about half as long as hind femora, moderately upcurved, apices; dorsal margins smooth, ventral margins with indistinct teeth at subapical areas (Fig. 9G).

Coloration. Male body brown, female darker. Eyes black. Ocelli pale.

Measurements (mm). BL: ♂ 18.9, ♀ 20.3; PL: ♂ 5.2, ♀ 5.4; FFL: ♂ 5.6, ♀ 6.0; MFL: ♂ 7.1, ♀ 7.1; HFL: ♂ 14.2, ♀ 15.9; HBL: ♂ 3.2, ♀ 3.3; OvL: 7.3.

Material examined. Holotype: male, Daweishan, Pingbian, Yunnan, August 14, 2022, coll. by Xiangyi Lu and Xiaoyu Peng. Paratype: 1 female, the other information as holotype.

Distribution. Yunnan (Pingbian).

Discussion. The new species differs from Rhaphidophora quadrula Bian, Zhu & Shi, 2017 (Lu et al., 2022: Fig. 12D, F) by basal margin of male epiproct widely arched, slightly longer than wide, dorsal surface faintly concave (Fig. 8E); male subgenital plate short, posterior margin wide (Fig. 8F).

Etymology. The new species refers to the male epiproct differing from the Rhaphidophora quadrula Bian, Zhu & Shi, 2017.
