Figs. 2–3
Description. Male. Body medium. Fastigium verticis projecting forward, dorsal surface with a longitudinal furrow in the midline (Fig. 2A). Eyes protruding outward. Lateral ocelli large, nearly occupying all the lateral margins of rostral tubercles; median ocellus smaller than lateral ocelli, oval (Fig. 2A). Anterior and posterior margins of pronotum projected; lateral lobes longer than deep, humeral sinus impressed, ventral margin arched (Fig. 2B). Fore coxae with 1 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 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. Hind tibiae with 18–19 internal spines, 17–19 external spines and 1 pair of small subapical spines on dorsal surface, apices with 1 pair of dorsal apical spines and 2 pairs of ventral apical spines; basitarsi with 4–5 spines and 1 apical spine on dorsal surface along the midline. Posterior margin of eighth abdominal tergite slightly projected in the middle. Posterior margin of ninth abdominal tergite with 1 trapezoidal process (Fig. 2D), dorsal surface of the processes slightly concave, seems with longitudinal furrow in dorsal view (Fig. 2D), and the apical margin almost straight. Tenth abdominal tergite narrow with arched concavity. The lateral margins of epiproct convex, posterior margin almost straight with small median concavity. Cerci slender, conical. Subgenital plate wider than long, posterior margin widely rounded (Fig. 2F); styli cylindrical, slightly compressed, its apices obtuse, inserted on posterolateral area of subgenital plate (Fig. 2F).
Female. Unknown.
Coloration. Body brown (Fig. 2), dorsal surface of thorax dark brown (Fig. 2C). Eyes black. Apices of hind femora with black spots.
Measurement (mm). BL: ♂ 28.6; PL: ♂ 7.6; FFL: ♂ 7.7; MFL: ♂ 7.8; HFL: ♂ 17.2; HBL: ♂ 3.2.
Material examined. Holotype: male, Bulangshan, Menghai, Yunnan, August 12, 2021, coll. by Haiqing Huang.
Distribution. Yunnan (Menghai).
Discussion. The species is very similar to Eurhaphidophora laosi Gorochov, 2010, but differs from it in: the process of male ninth abdominal tergite longer and narrower; dorsal surface slightly longitudinal concave; male subgenital plate wider than long. In Eurhaphidophora laosi, the process of male ninth abdominal tergite is wider dorsally and without a longitudinal groove.
Etymology. Named for the process of male ninth abdominal tergite with indistinct longitudinal groove in dorsal surface; from Latin word “ foss ”.
