Fig. 13

Description. Female. Body medium. Face with fine transverse riffles. Lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus smaller than lateral ocelli, oval, situated under antennal sockets ( Fig. 1A–B ). Apical segment of maxillary palpi nearly equal to subapical segment, apices slightly inflated. Anterior margin of pronotum almost straight, posterior margin widely rounded ( Fig. 13B ); lateral lobes longer than high, anterior angle widely rounded, posterior angle rounded ( Fig. 13C ). Fore coxae obviously inflated, with 1 spine; femora with 1 short ventral 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 on ventral surface; tibiae with 2 pairs of spines on dorsal surface, ventral surface with 2 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind tibiae with 18–20 pairs of spines and 1 pair of small subapical spines on dorsal surface, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 3–5 spines and 1 apical spine on dorsal surface along the midline. Tenth abdominal tergite with median concavity on posterior margin. Epiproct lingulate with longitudinal furrow on dorsal surface. Cerci slender. Subgenital plate nearly triangular, lateral margins terminating and constricted in the middle area ( Fig. 13F ). Ovipositor shorter than hind femora, moderately upcurved, dorsal margins smooth, apices acute; apical area of ventral margins with indistinct small teeth ( Fig. 13E ).

Male. Unknown.

Coloration. Body black brown. Legs brown.

Measurement (mm). BL: ♀ 21.1; PL : ♀ 7.6; FFL : ♀ 8.3; MFL : ♀ 8.4; HFL : ♀ 19.4; HBL : ♀ 4.8; OvL : 12.8.

Material examined. Holotype: female, Yangmeiao, Rongshui , Guangxi, August 1, 2019, coll. by Wei Bin, Ganlian Pang & Xiaodan Liang.

Distribution. Guangxi (Rongshui).

Discussion. The new species differs from Rhaphidophora incilis Gorochov, 2012 in the lateral margins of female subgenital plate narrowing to the apex and not obviously constricted ( Fig. 13E ).

Etymology. Named after the type locality; noun in apposition.
