Description. Male. Body medium. Head and pronotum as other species of the genus. Legs. Fore coxae with 1 spine; femora apically with 1 internal spine; 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; tibiae dorsally with 1 pair 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 internal spine ( Fig. 3E ); tibiae dorsally with 23–25 internal spines, 22–23 external spines and 1 pair of small subapical spines, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 4 small spines and 1 apical spine on dorsal surface along the midline ( Fig. 3F ).

Abdomen. Posterior margin of tenth abdominal tergite arched concave. Epiproct bent downward ( Fig. 3G ): lateral margins with basal half convex and faintly converging, apical half obviously converging and curving down and forward; dorsal surface with 1 large spine on each side at transition between from basal to apical area, apical margin 1 pair of small spines ( Fig. 3I ). Cerci longer, curving upwards at apical area ( Fig. 3G ). Subgenital plate wider than long, ventral surface convex, posterior margin almost straight; styli conical, inserted on posterolateral areas of the plate ( Fig. 3J ).

Female. Unknown.

Coloration. Male body brown, dorsum of head blackish brown.

Measurements (mm). BL: ♂ 15.3; PL: ♂ 5.1; FFL: ♂ 7.2; MFL: ♂ 7.2; HFL: ♂ 15.0; HTL: ♂ 14.2; HBL: ♂ 33.0.

Material examined. Holotype: male, Hanmi, Motuo , Xizang, July 30, 2024, coll. by Siyu Pang and Ting Luo.

Distribution. Xizang (Motuo).

Discussion. The new species differs from Rhaphidophora shii Lu & Bian, 2022 by: male epiproct wider with 1 pair of conical lateral spines in middle; apical margin of epiproct with 1 large posteriolateral spine on each side; male subgenital plate with conical styli.

Etymology. The new species' name refers to male subgenital plate with conical styli.
