Fig. 16

Description. Male. Body small. Anterior and posterior margins of pronotum projected, lateral lobes longer than high, ventral margin arched ( Fig. 16B ). 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 armed dorsally with 2 pairs of spines, ventral surface with 1 internal and 3 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Dorsal surface of hind tibiae with 19–21 internal, 19–21 external and 1 pair of small subapical spines, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 4–5 spines and 1 apical spine on dorsal surface along the midline ( Fig. 16H ). Abdominal tergites without any processes. Epiproct directing downwards, with 1 pair of long, parallel spines on posterior margin; ventral surface with 1 robust process, the apical margin of process arched with 1 spine on each side ( Fig. 16E–F ). Cerci slender, conical, apices acute. Subgenital plate wider than long, posterior margin arched ( Fig. 16G ); styli long, about as wide as subgenital plate, its apices obtuse, inserted on the posterolateral area of subgenital plate ( Fig. 16G ).

Female. Unknown.

Coloration. Body brown. Terga black. Ocelli pale. Ventral surface of antennae light brown.

Measurement (mm). BL: ♂ 15.1–16.0; PL: ♂ 6.0; FFL: ♂ 6.0–6.4; MFL: ♂ 6.0–7.1; HFL: ♂ 15.7–16.0; HBL: ♂ 3.0–3.7.

Material examined. Holotype: male, Mangzhen, Gengma , Yunnan, August 7, 2021, coll. by Xiangyi Lu, Xiaojuan Huang and Zhenyong Huang . Paratype: 1 male, Mengsa, Gengma, Yunnan, August 6, 2021, coll. by Xiangyi Lu , Xiaojuan Huang and Zhenyong Huang .

Distribution. Yunnan (Gengma).

Discussion. The species differs from Rhaphidophora furcifera Gorochov, 2013 : the processes of male epiproct parallel and spine-shaped, its apices acute; ventral surface of epiproct with 1 robust process, and apical margin of the process arched with 1 large spine on both sides ( Fig. 16E–G ); the length of styli as wide as male subgenital plate, the posterior margin of male subgenital plate arched ( Fig. 16G ). While Rhaphidophora furcifera , the process of male epiproct with apices obtuse and connected each other, the length of styli longer than the width of male subgenital plate, the posterior margin of male subgenital plate roundly concave.

Etymology. The new species name is derived from appearance of the male epiproct with 2 long spines; from Latin word “ spin ”.
