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 2 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 17–20 internal spines, 20–21 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. 3F).
Apex of abdomen curved downwards. Posterior margin of tenth abdominal faintly concave in middle. Epiproct longer than wide in apical view, middle area furrowed (Fig. 3H); lateral margins convex and then prolonged into a cylindrical process on each side, between the processes U-shaped (Fig. 3H), at subapical areas of the processes terminating into a short spine (Fig. 3J), directing forwards (Fig. 3G); ventral surface of the processes with transverse carina; the lateral margin of apical half terminating, apical area with 1 spine on each side (Fig. 3L), posterior margin arched. Paraprocts sclerotized, conical, prolonged into a spine, apical half incurved. Cerci slender, conical, apices acute. Subgenital plate wider than long, posterior margin almost straight; styli inserted on posterolateral area of the plate (Fig. 3J), apices obtuse.
Female. Tenth abdominal tergite concave in middle (Fig. 4G). Epiproct roughly triangular, dorsal surface concave with median furrow, posterior margin narrowly rounded (Fig. 4G). Cerci slender. Subgenital plate semioval, lateral margins terminating, posterior margin arched concave (Fig. 4I). Ovipositor about half as long as hind femora, moderately upcurved, apices acute; dorsal valvulae smooth, apical areas of ventral valvulae slightly serrate on ventral margins (Fig. 4H).
Coloration. Male body brown, female darker.
Measurements (mm). BL: ♂ 20.55–21.84, ♀ 20.64–23.10; PL: ♂ 6.65–6.75, ♀ 6.98–7.66; FFL: ♂ 7.20–8.40, ♀ 8.08–9.28; MFL: ♂ 7.80–8.02, ♀ 8.29–9.39; HFL: ♂ 17.08–18.47, ♀ 17.82–21.88; HBL: ♂ 3.07–3.43, ♀ 4.22–4.36; OvL: 8.51–9.08.
Material examined. Holotype: male, Tongbiguan, Yingjiang, Yunnan, August 20, 2023, coll. by Siyu Pang and Ting Luo. Paratypes: 1 male and 1 female, the other information as holotype; 1 female, Xima, Yingjiang, Yunnan, August 14, 2023, coll. by Weizong Yang.
Distribution. Yunnan (Yingjiang).
Discussion. The new species differs from other species of Rhaphidophora by middle area of male epiproct arched with 1 pair of short cylindrical processes (Fig. 3H), terminating into a spine at apical area (Fig. 3J), followed with 1 transverse carina on ventral surface, then constricted at subapical area, posterior margin with 1 spine on each side; male paraprocts strongly sclerotized, prolonged into spine, apices acute (Fig. 3K); posterior margin of female subgential plate with median notch (Fig. 4I).
Etymology. The name of the new species is given for the processes of male epiproct nearly cylindrical in dorsal view; from Greek word “ cylindr ”.
