Figs. 2–4

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). 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). Fore coxae with 1 spine (Fig. 2C); 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) 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). Epiproct directing downwards, the middle area with 1 pair of digitate processes, then obviously narrowing to apex (Fig. 2F–G); the apical half inverted trapezoidal which mostly invisible in dorsal surface, apical margin with 1 pair of spines (Fig. 2F). 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, 3I).

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

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.

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), posterior margin of male arched, styli stout (Figs. 2H, 3I); 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 ”.
