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
).

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.
