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 2 internal and 3 external 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 (Fig. 2G); 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 3–6 small spines and 1 apical spine on dorsal surface along the midline (Fig. 2F).

Posterior margin of tenth abdominal tergite projected in middle, with narrow and deep concavity (Fig. 2H). Epiproct ligulate, dorsal surface concave, apex rounded (Fig. 2H). Cerci slender, apices subacute. Subgenital plate wider than long, the lateral margins obliquely narrowing and terminating into a small spine at apex (Fig. 2I). Ovipositor slightly shorter than hind femora, moderately upcurved, dorsal margins smooth, apices acute; ventral margins with small teeth at apical areas (Fig. 2D).

Male. Unknown.

Coloration. Body brown. Head brownish, below eyes with black spots, fronto-clypeal suture with 1 pair of black spots. Apices of hind femora black.

Measurements (mm). BL: ♀ 26.08; PL: ♀ 6.88; FFL: ♀ 7.92; MFL: ♀ 7.86; HFL: ♀ 19.33; HBL: ♀ 3.46; OvL: 16.08.

Material examined. Holotype: female, Xima, Yingjiang, Yunnan, August 15, 2023, coll. by Weizong Yang.

Distribution. Yunnan (Yingjiang).

Discussion. The new species differs from Rhaphidophora digitata Lu & Bian, 2022 by lateral margins of female subgenital plate obliquely narrowing, posterior margin with longer spine (Fig. 2I). While in Rhaphidophora digitata Lu & Bian, 2022, the posterior margin of female subgenital plate widely arched (Lu et al., 2022: Fig. 4F), the median spine short.

Etymology. The name of the new species derives from Greek word “ brachy ” referring to the female subgenital plate with 1 short spine at posterior margin.
