Description. Male. Body small. Fastigium verticis as other species of the genus. Lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus as large as lateral ocelli ( Fig. 2A–B View FIGURE 2 ). Apical segment of maxillary palpi longer than subapical segment, apices slightly inflated. Anterior margin of pronotum almost straight, posterior margin widely rounded, lateral lobes longer than high, ventral margin arched ( Fig. 2B–C View FIGURE 2 ). Fore coxae with 1 spine ( Fig. 2C View FIGURE 2 ); 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 2 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind tibiae with 19–21 pairs of spines and 1 pair of small subapical spines on dorsal surface, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 4–5 spines ( Fig. 3J View FIGURE 3 ) and 1 apical spine on dorsal surface along the midline. Posterior margin of eighth and ninth abdominal tergites slightly projected. Posterior margin of tenth abdominal tergite projected with middle area arched ( Fig. 2E View FIGURE 2 ). Epiproct directing downwards, the middle area with 1 pair of digitate processes, then obviously narrowing to apex ( Fig. 2F–G View FIGURE 2 ); the apical half inverted trapezoidal which mostly invisible in dorsal surface, apical margin with 1 pair of spines ( Fig. 2F View FIGURE 2 ). Cerci slender, conical, apices acute. Subgenital plate wider than long, the lateral margins convex in middle area, then terminating, posterior margin arched; styli stout and short, its apices obtuse, inserted on the posterolateral area of subgenital plate ( Fig. 2H View FIGURE 2 , 3I View FIGURE 3 ).

Female. Posterior margin of tenth abdominal tergite with narrow and deep concavity ( Fig. 4D View FIGURE 4 ). Epiproct longer than wide. Cerci slender. Subgenital plate longer than wide, the lateral margins narrowing, posterior margin arched with 1 small angle ( Fig. 4F View FIGURE 4 ). Ovipositor shorter than hind femora, moderately upcurved, dorsal margins smooth, apices acute; ventral margins with indistinct teeth nearly apices ( Fig. 4E View FIGURE 4 ).

Coloration. Body brown, terga with small black spots, sterna yellowish brown. Apices of femora with large blackish spots on dorsal surface. Basal area of tibiae blackish.

Measurement (mm). BL: ♂ 14.6–15.3, ♀ 13.3–14.8; PL : ♂ 5.1–5.5, ♀ 5.3–5.4; FFL : ♂ 5.4–6.1, ♀ 6.1–6.5; MFL : ♂ 5.9–6.3, ♀ 6.1–6.6; HFL : ♂ 13.2–13.6, ♀ 14.1–15.1; HBL : ♂ 2.7–3.3, ♀ 3.2–3.6; OvL : 9.9–10.4.

Material examined. Holotype: male, Banmai, Gengma , Yunnan, July 29, 2021, coll. by Xiangyi Lu, Xiaojuan Huang and Zhenyong Huang . Paratypes: 2 female nymphs, August 1, 2021 and 2 males, August 2, 2021, other information as holotype; 1 male, Nantianmen, Gengma , Yunnan, July 24, 2021, coll. by Xiangyi Lu, Xiaojuan Huang and Zhenyong Huang .

Distribution. Yunnan (Gengma).

Discussion. The new species name differs from Rhaphidophora spinifera Gorochov, 2013 by: the apical spines of male epiproct large ( Fig. 2E View FIGURE 2 ), posterior margin of male arched, styli stout ( Figs. 2H View FIGURE 2 , 3I View FIGURE 3 ); female subgenital plate with small angle on posterior margin.

Etymology. The new species is named for the shape of the styli of the male subgenital plate; from Latin word “ digit ”.
