Description. Male. Body medium sized. Fastigium verticis projecting forward, dorsal surface with a longitudinal furrow in the midline, divided fastigium verticis into 2 distinct rostral tubercles with the apical area separated from each other ( Fig. 5 A). Eyes protruding outward. Lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus smaller than lateral ocelli, oval, situated under antennal sockets ( Fig. 5 B). Apical segment of maxillary palpi nearly equal to subapical segment, apices slightly inflated. Anterior and posterior margins of pronotum projecting, lateral lobes longer than high, ventral margin straight ( Fig. 5 B). Posterior margin of mesonotum distinctly prolonging backward, posterior margin of lateral lobes slightly concave, ventral margin nearly rectangular ( Fig. 5 C). Metanotum slightly extending, posterior margin of lateral lobes arched concave ( Fig. 5 C). Fore coxae obviously inflated, with a small spine; femora with an inner apical spine on ventral surface; tibiae with an inner spine and 2 outer spines on ventral surface, apices armed ventrally with 1 pair of spines on both margins. Ventral surface of middle femora with 1 pair of apical spines, the internal spine obviously longer than the external one; tibiae armed dorsally with 2 pairs of spines and 1 pair of apical spines, ventral surface with 1 internal spine and 2 external spines, apices with 1 pair of spines. Genicular lobes of hind femora with an internal apical spine; tibiae with 20 internal and 19 external spines on dorsal surface, subapices with 1 pair of dorsal spines, ventral surface unarmed, apices with 1 pair of dorsal spines and 2 pairs of ventral spines, the external apical spines obviously longer than internal ones. Dorsal surface of hind basitarsi with 4 spines and 1 apical spine. Abdominal tergite without any processes. Basal area of epiproct nearly semicircular in dorsal view, apical area with 1 pair of long spines pointing ventrad and slightly backward ( Fig. 5 D); ventral surface of apical area with 1 long, robust spine, its apices directing forward and slightly ventrad ( Fig. 5 E). Cerci slender, apical half curved outward. Subgenital plate wider than long, posterior margin almost straight; styli about 1.5 times longer than the length of subgenital plate, cylindrical, apical obtuse, located on apical area of subgenital plate ( Fig. 5 F).

Female. Unknown.

Coloration. Body brown, abdominal sternites and legs yellowish brown, spines of hind tibiae black brown.

Measurement (mm). BL: ♂16.5; PL: ♂6.5; FFL: ♂7.3; HFL: ♂16.5; HTL: ♂15.5; HBL: ♂3.6.

Material examined. Holotype: male, Caiyang River, Pu ′er, Yunnan, 28 July, 2007, coll. by Guodong Ren.

Distribution. China (Yunnan).

Discussion. The species can be easily distinguished from Rhaphidophora furcifera Gorochov, 2013 and Rhaphidophora brevispinula sp. nov. in: basal half of male epiproct rather short, the spines of apical area distinctly longer than the other two species, styli longer than subgenital plate.

Etymology. Name is derived from male epiproct with 1 pair of long spines.
