Description. Female. 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 1 internal and 1–2 external spines, ventral surface with 1 internal and 1–2 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 18–20 internal spines, 19–22 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. 5E ).

Posterior margin of tenth abdominal tergite concave in middle ( Fig. 5H ). Epiproct ligulate, longer than wide, dorsal surface with median furrow, apex rounded ( Fig. 5H ). Cerci slender, apices acute. Subgenital plate semicircular in ventral view, ventral surface convex, posterior margin rounded with median furrow ( Fig. 5I ). Ovipositor slightly longer than half of hind femora, upcurved, dorsal valvulae smooth, apices acute; apical areas of ventral valvulae with indistinct teeth ( Fig. 5G ).

Male. Unknown.

Coloration. Body brown, head with black patterns, eyes black.

Measurements (mm). BL: ♀ 15.2–15.3; PL: ♀ 4.9–6.7; FFL: ♀ 6.3–6.7; MFL: ♀ 6.8–6.9; HFL: ♀ 16.6–17.6; HBL: ♀ 2.9–3.3; OvL: 8.9–10.7.

Material examined. Holotype: female, Diding, Jingxi , Guangxi, June 10, 2023, coll. by Siyu Pang and Shan Li . Paratype: 1 female, the other information as holotype.

Distribution. Guangxi (Jingxi).

Discussion. The new species differs from Rhaphidophora minuolamella Liu & Zhang, 2002 by female epiproct ligulate ( Fig. 5H ) instead of triangular; female subgenital plate roughly semicircular in ventral view, posterior margin rounded with median furrow on ventral surface ( Fig. 5I ). The female of the latter species has triangular subgenital plate.

Etymology. Named after the type locality.
