Fig. 1

Description. Male. Body medium. Face smooth (Fig. 1A). Dorsal surface of fastigium verticis with a longitudinal median furrow, which divides fastigium verticis into 2 distinct rostral tubercles with the apical area separated from each other (Fig. 1B). Eyes protruding outwards. Lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus smaller than lateral ocelli, oval (Fig. 1A–B). Anterior margin of pronotum almost straight, posterior margin slightly projecting backwards (Fig. 1C); lateral lobes longer than deep, anterior angle widely rounded, posterior angle rounded, ventral margin arched (Fig. 1D). Fore coxae with 1 small 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 1 pair of spines, ventral surface with 2 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Dorsal surface of hind tibiae with 18 internal spines, 19–20 external spines and 1 pair of small subapical spines, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 3 spines and 1 apical spine on dorsal surface along the midline (Fig. 1K). Posterior margin of eighth abdominal tergite angularly projected in the middle (Fig. 1G–H). Posterior margin of ninth abdominal tergite with 1 median process curved downwards which not separated from the tergite (Fig. 1G); the lateral margin of subapical area of the process slightly widened, apical margin straight (Fig. 1F), dorsal surface of basal half with indistinct carina. Epiproct concave ventrad, cupshaped, posterior margin widely rounded. Cerci slender, conical, apices subacute (Fig. 1I). Subgenital plate wider than long, posterior margin arched; styli stout, inserted on posterolateral area of subgenital plate (Fig. 1J).

Female. Unknown.

Coloration. Body black brown, abdominal sternites pale brown, legs yellowish with black spots. Eyes black. Ocelli pale.

Measurement (mm). BL: ♂ 25.4; PL: ♂ 6.6; FFL: ♂ 7.4; MFL: ♂ 7.6; HFL: ♂ 17.3; HBL: ♂ 3.7.

Material examined. Holotype: male, Banmai, Gengma, Yunnan, July 29, 2021, coll. by Xiangyi Lu, Xiaojuan Huang and Zhenyong Huang.

Distribution. Yunnan (Gengma).

Discussion. The new species is close to both Eurhaphidophora ampla Gorochov, 2010 and Eurhaphidophora orlovi Gorochov, 2010, but differs from them in: the process of male ninth abdominal tergite wider and not separated from the tergite, apical area of process slightly widened, apical margin almost straight; the apical margin of epiproct widely rounded without apical lobes; posterior margin of male subgenital plate slightly projected.

Etymology. The new species name refers to the process of male ninth abdominal tergite curved downward; from Latin word “ curv ”.
