Figures 1–2
Description. Male. Body large. Head. Face smooth (Fig. 1A). Dorsal surface of fastigium verticis with a longitudinal deep median furrow, apices which divide fastigium verticis into 2 distinct rostral tubercles with the apical area separated from each other (Fig. 1B). Eyes ovoid, protruding forward; lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus slightly smaller than lateral ocelli, oval (Fig. 1A–B). Apical segments of maxillary palpi obviously longer than subapical ones, apices slightly inflated. Thorax. Anterior margin of pronotum slightly projecting, posterior margin protruding backward and widely rounded (Fig. 1C); lateral lobes longer than high, ventral margin undulate (Fig. 1D). Posterior margin of mesonotum protruding backward, posterior margin of metanotum faintly protruding. Fore coxae swollen with 1 stout spine; femora with 1 short 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; tibiae dorsally with 2 pairs of spines, ventral surface with 2 pairs of spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind femora with 1 short ventral spine on internal margin (Fig. 1E); tibiae dorsally with 17–18 internal spines, 18–19 external spines and 1 pair of small subapical spines, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 6 small spines and 1 large apical spine on dorsal surface along the midline (Fig. 1G). Abdomen. Apex of abdomen curved downwards. Posterior margin of fifth abdominal tergite widely rounded projecting in middle; posterior margin of sixth abdominal tergite with 1 large rectangular median lobe, its apical margin almost straight; the posterior lobes of seventh abdominal completely concealed under the preceding tergite; posterior margin of eighth abdominal tergite faintly projecting with faintly concave in middle; posterior margin of ninth abdominal tergite widely arched; tenth abdominal tergite slightly prolonged with apical margin faintly concave in middle (Fig. 1H). Epiproct longer than wide in apical view, ventral surface furrowed along the midline (Fig. 1K); lateral margins converging, obviously constricted at subapical area and then convex, apical margin rounded with a small concavity (Fig. 1K). Cerci slender, conical, apices acute. Subgenital plate semielliptical, basal margin straight, posterior margin faintly projecting in middle (Fig. 1M); styli roughly cylindrical, inserted at subapical area of the plate on ventral surface, apices obtuse (Fig. 1L). Genitalia entirely membranous.
Female. Abdomen. Posterior margin of fourth abdominal tergite faintly projecting; posterior margin of fifth abdominal tergite arched projecting in middle; posterior margin of sixth abdominal tergite nearly trapezoidal projecting, its apical margin almost straight or faintly concave; posterior margin of seventh abdominal tergite widely trapezoidal projecting (Fig. 2G, H). Epiproct roughly oval, dorsal surface concave with median furrow, posterior margin narrowly rounded (Fig. 2I). Cerci slender. Subgenital plate transverse at base, triangularly narrowing posteriorly and terminating into a short spiniform apical area; basal area as long as apical area, lateral margins distinctly constricted at transition between basal and apical areas (Fig. 2L). Ovipositor gradually upcurved behind base, apices acute; dorsal valvulae smooth, apical areas of ventral valvulae serrate on ventral margins (Fig. 2K).
Coloration. Dorsal surface of abdomen brown, ventral surface lighter. Eyes black, ocelli pale yellow. Dorsal spines of hind tibiae brown.

Distribution. Hainan (Jianfengling, Wuzhishan).
Discussion. The new species differs from Sinorhaphidophora hainanensis (Bian & Shi, 2016) in the following: the process of male fifth abdominal tergite short (Fig. 1I); the process of six abdominal tergite longer with posterior margin almost straight (Fig. 1I) instead of concave (Fig. 6G); male epiproct elongate with lateral margins converging after middle area and subapical area constricted, apical area convex (Fig. 1K); styli cylindrical (Fig. 1L); the apical spine of female subgenital plate narrow (Fig. 2L).
Etymology. The name of the new species is given for the longer processes of male sixth abdominal tergite.
