Description. Male. Body medium. Fastigium verticis protruding, formed by two elliptical tubercles sulcated longitudinally (Fig. 1 A). Eyes projecting outward. Lateral ocelli oval, occupying basal half of lateral margins; median ocellus large, circular, situated on between antennal sockets. Apical segment of maxillary palpi nearly as long as subapical segment, apices slightly inflated. Anterior margin of pronotum slightly projecting, posterior margin obviously projecting (Fig. 1 B); ventral margins of lateral lobes arched, the posterior margin slightly concave (Fig. 1 C). Fore coxae swollen with 1 small spine; femora armed ventrally with 1 apical spine on internal margin; tibiae with 1 internal spine and 2 external spines on ventral surface, apices with 1 pair of spines on dorsal and ventral surface separately. Middle femora with 1 pair of apical spines; tibiae armed dorsally with 2 pairs of spines, ventral surface with 2 external spines, apices with 1 pair of dorsal and ventral spines separately, of which dorsal apical spines obviously longer than ventral ones. Genicular lobes of hind femora with 1 internal spine, external lobe obtuse; dorsal surface of tibiae bearing 18–21 spines on both margins, subapical area with 1 pair of dorsal spines, apices with 1 pair of dorsal spines and 2 pairs of ventral spines. Dorsal surface of hind basitarsi with 4–5 small spines and 1 apical spine in the midline (Fig. 1 E). Abdominal tergites without any processes, posterior margin of tenth abdominal tergite slightly concave. Basal area of male epiproct broad, narrowing to apex, slightly expanded at apex, its dorsal surface slightly concave in the midline; dorsal surface with a median furrow (Fig. 1 D). Cerci slender, conical, apices subacute. Subgenital plate longer than wide, posterior margin almost truncate, with stout styli (Fig. 1 E–F).
Female. Unknown.
Coloration. Dorsal surface of body brown, ventral surface yellowish brown. External surface of hind femora with oblique blackish brown stripes, spines and apices of claws black.
Measurements (mm). BL: ♂ 18.2–20.5; PL: ♂ 7.4–7.6; FFL: ♂ 8.0–8.2; HFL: ♂ 17.2–18.5; HTL: ♂ 15.5–16.5; HBL: ♂ 3.8–4.0.
Material examined. Holotype: male, Bawangling, Changjiang, Hainan, China, 15 June, 2014, coll. Ming Qiu and Ruilian Li. Paratype: 1 male, Bawangling, Changjiang, Hainan, China, 31 May, 2014, coll. By Jiao Jiao.
Distribution. China (Hainan).
Discussion. The new species differs from Rhaphidophora vasiliji Gorochov, 1999 and Rhaphidophora abramovi Gorochov, 2012 by: dorsal surface of male epiproct with an obviously longitudinal furrow in the midline; apical area expanded, posterior margin slightly concave in the middle. Rhaphidophora vasiliji Gorochov, 1999 distributed in Gia Lai Province, Vietnam has one longitudinal carina on dorsal surface of male epiproct apically; while Rhaphidophora abramovi Gorochov, 2012 occurred in Lam Donf Province, Vietnam has the following characters: male epiproct elongate, dorsal surface of apical quarter flat, without any longitudinal carina or furrow, apical area slightly expanded.
Etymology. Name is derived from Latin ‘ bi ’ plus ‘ procer ’, referring to the shape of male epiproct.
