Description. Male. Body medium sized. Fastigium verticis elongate, dorsal surface with a deep furrow dividing the rostrum into two rostral tubercles, which depressed and not connecting with each other ( Fig. 7 View FIGURE 7 A). Eyes nearly triangular in dorso-lateral view. Lateral ocelli oval, occupying two sides of rostral tubercles ( Fig. 7 View FIGURE 7 B); median ocellus large locating under the antennal socket ( Fig. 7 View FIGURE 7 B). Apical segment of maxillary palpi subequal to subapical one. Lateral lobes of pronotum slightly concave on ventral margin ( Fig. 7 View FIGURE 7 C); posterior margin of mesonotum projecting ( Fig. 7 View FIGURE 7 C). Fore coxae distinctly inflated, with a small spine; femora with an internal apical spine on ventral surface; tibia of left fore leg with an internal spine at subapical area and an external spine in the middle ventrally, right one armed ventrally with 1 pair of spines in the middle area and 1 large external spine; apices of fore tibiae with a pair of spines, the internal ones slightly longer. Middle femora with 1 large apical spine on ventral surface; tibiae with 2 pairs of spines and 1 pair of apical spines on dorsal surface, ventral surface with 1 internal spine, 2–3 external spines and 1 pair of dorsal apical spines, dorso-apical spines obviously longer than ventroapical ones. Hind femora unarmed on ventral surface, genicular lobes obtuse; tibiae with 20 internal spines and 18– 21 external spines on dorsal surface, apices with 1 pair of long dorsal spines and 2 pairs of short ventral spines, the internal spines slightly longer than the external ones. Dorsal surface of hind basitari with 5 small spines and 1 large apical spine along the middle carina. Abdominal tergite without processes, posterior margin of tenth abdominal tergite slightly concave. Epiproct subrectangular in dorsal view, dorsal surface with a distinct longitudinal furrow in the midline, the lateral margin obviously raised; the lateral margins of epiproct right-angular curved ventrad, posterior margin nearly truncate ( Fig. 7 View FIGURE 7 D–E). Cerci slender, conical, apices acute ( Fig. 7 View FIGURE 7 F). Subgenital plate longer than broad, basal margin almost straight, posterior margin slightly protruding; styli nearly as long as subgenital plate, cylindrical, ventral surface with a longitudinal furrow at apical two-thirds area ( Fig. 7 View FIGURE 7 G).

Female. Unknown.

Coloration. Body brown, sternites and all legs yellowish-brown.

Measurements (mm). BL: ♂ 19.0; PL: ♂ 6.8; FFL: ♂ 8.0; HFL: ♂ 16.2; HTL: ♂ 15.6; HBL: ♂ 4.0.

Material examined. Holotype: male, Damingshan, Wuming , Guangxi, 5 August, 2010, coll. by Xun Bian and Xuping Yan.

Distribution. China (Guangxi).

Discussion. The species is very similar to Rhaphidophora longa Gorochov, 1999 , but it can be easily distinguished from the latter in: male epiproct as long as wide, dorsal surface with 1 longitudinal furrow along the midline. While in Rhaphidophora longa Gorochov, 1999 , male epiproct rectangular, longer than wide, dorsal surface with 1 longitudinal carina in the midline.

Etymology. Name derived from Latin “ quadrul ” meaning the shape of male epiproct.
