Description. Female. General appearance smaller than other species of the genus. Head. Face smooth (Fig. 5A). Dorsal surface of fastigium verticis with a longitudinal furrow in the midline, apices which divide fastigium verticis into 2 distinct rostral tubercles with the apical area separated from each other (Fig. 5B). Eyes ovoid, protruding forward; lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus oval, slightly smaller than lateral ocelli (Fig. 5A–B). Apical segments of maxillary palpi about two times as long as subapical ones, apices faintly inflated. Thorax. Anterior margin of pronotum slightly projecting, posterior margin protruding backward (Fig. 5C); lateral lobes longer than high, ventral margin arched. Posterior margin of mesonotum protruding backward, posterior margin of metanotum faintly protruding. Fore coxae convex with 1 spine; femora with 1 short apical 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 2 pairs of spines, ventral surface with 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 18–19 internal spines, 18–20 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 large apical spine on dorsal surface along the midline (Fig. 5E). Abdomen. Posterior margin of fourth abdominal tergite faintly projecting in middle; fifth abdominal tergite with a very short and rounded posteromedian process; sixth abdominal tergite with 1 short posteromedian process, its longer than the preceding tergite, apical margin faintly concave (Fig. 5G). 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. Basal margin of subgenital plate transverse, before middle gradually narrowing and terminating into a spine (Fig. 5J). 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, abdominal tergites darker. Eyes black. Ocelli pale yellow.

Measurements (mm). BL: ♀ 20.90–22.87; PL: ♀ 7.30–8.60; FFL: ♀ 8.78–9.63; MFL: ♀ 8.45–8.80; HFL: ♀ 20.43–20.67; HBL: ♀ 3.84–4.15; OvL: 12.08–12.91.

Material examined. Holotype: female, Wuzhishan, Hainan, May 21, 20244, coll. by Ting Luo and Yanting Qin . Paratypes: 2 females, the other information as holotype; 1 female, Yinggeling, Haiyan, June 9, 2024, coll. by Yanting Qin and Yizhen Yao ; 1 female, Limushan, Hainan, June 5, 2024, coll. by Yanting Qin and Yizhen Yao .

Distribution. Hainan (Limushan, Wuzhishan, Yinggeling).

Discussion. The new species differs from Sinorhaphidophora hainanensis (Bian & Shi, 2016) by body smaller than other species of the genus; female epiproct slightly wider than long (Fig. 4H), dorsal surface concave.

Etymology. The name of the new species refers to the smaller body.
