Fig. 1

Description. Male. Body small. Face with fine transverse riffles (Fig. 1A). Dorsal surface of fastigium verticis with a longitudinal furrow in the midline, apices which divide fastigium verticis into 2 distinct rostral tubercles with the apical area separated from each other (Fig. 1B). Lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus slightly smaller than lateral ocelli, oval (Fig. 1A–B). Apical segment of maxillary palpi nearly equal to subapical segment, apices slightly inflated. Anterior margin of pronotum slightly projected, posterior margin widely rounded (Fig. 1B). Fore coxae obviously inflated, with 1 minute spine; femora with 1 short apical 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 1 internal and 3–4 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Dorsal surface of hind tibiae with 22–23 internal spines, 19–21 external spines, 1 pair of small subapical spines and 1 pair of apical spines, ventral surface with 2 pairs of apical spines; basitarsi with 6–7 spines and 1 apical spine on dorsal surface (Fig. 1K). Posterior margin of eighth and ninth abdominal tergites with small projections (Fig. 1E). Posterior margin of tenth abdominal tergite with sub-trapezoidal projection (Fig. 1E). Epiproct longer than wide and directed downwards, dorsal surface concave, the lateral margins convex (Fig. 1G); apical margin with 1 pair of processes, the apical half of the process compressed, ventral surface with 1 short lobe, its apex with 1 small spine on both sides (Fig. 1F–I). Cerci slender, conical, apices acute. Subgenital plate wider than long, posterior margin almost straight; styli long, conical, its apices obtuse, inserted on the posterolateral area of subgenital plate (Fig. 1L).

Measurement (mm). BL: ♂ 15.3–17.5; PL: ♂ 5.5–6.1; FFL: ♂ 6.8–7.6; MFL: ♂ 5.9–7.1; HFL: ♂ 13.0–15.3; HBL: ♂ 2.7–3.1.

Coloration. Body brown, terga with black spots. Face black brown. Ocelli pale.

Material examined. Holotype: male, Mengsa, Gengma, Yunnan, August 5, 2021, coll. by Xiangyi Lu, Xiaojuan Huang and Zhenyong Huang . Paratypes: 3 males, Daxing, Gengma, Yunnan, August 2, 2021, Xiangyi Lu .

Distribution. Yunnan (Gengma).

Discussion. The species differs from Rhaphidophora spinifera Gorochov, 2013 in: the process of male epiproct with compressed apices (Fig. 1I–J), posterior margin of male subgenital plate almost straight (Fig. 1K); while the process of Rh. spinifera with cylindrical apices and male subgenital plate with triangular concavity.

Etymology. The new species name refers to the syli with compressed apices; from Latin word “ complan ”.
