Fig. 11

Description. Female. Body large. 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. 11A–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. 11B ); lateral lobes longer than high, anterior angle widely rounded, posterior angle rounded ( Fig. 11C ). 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. Apices of middle femora with 1 pair of spines on ventral surface; tibiae dorsally with 2 pairs of spines, ventral surface with 2 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind tibiae dorsally with 18–20 pairs of spines and 1 pair of small subapical spines, 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 ( Fig. 11G ). Tenth abdominal tergite with median concavity on posterior margin ( Fig. 11D ). Epiproct lingulate with longitudinal furrow on dorsal surface ( Fig. 11D ). Cerci slender. Subgenital plate longer than wide, the lateral margins narrowing, the middle of lateral margins faintly constricted, the apical half spine-shaped, apices acute ( Fig. 11F ). Ovipositor shorter than hind femora, moderately upcurved, dorsal margins smooth, apices acute; apical quarter of ventral margins with indistinct small teeth ( Fig. 11E ).

Male. Unknown.

Coloration. Body black brown. Ocelli pale.

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, Mohan, Mengla , Yunnan, August 1, 2019, coll. by Mingyin Guo.

Distribution. Yunnan (Mengla).

Discussion. The new species differs from Rhaphidophora incilis Bian, Zhu & Shi, 2017 in the lateral margins of female subgenital plate narrowing to apex and faintly constricted ( Fig. 11F ).

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