Male. Body medium sized. Fastigium verticis divided in apical half by a deep furrow forming a pair of rostral tubercles which depressed to each other (Fig. 5 A–B). Lateral ocelli oblong, occupying basal two-thirds of lateral surface of rostral tubercles; median ocellus nearly triangular, the length obviously longer than scape (Fig. 5 A). Anterior margin of prontoum almost straight, posterior margin obtusely rounded projected; ventral margins of lateral lobes slightly convex; ventral margins of mesonotum slightly oblique (Fig. 5 B–C). Armament of legs: fa 1; ff v1 a; ft v2 o– 1i, v2 a; mf v2 a; mt de, di, d2a, v2 o, v2 a; hf via; ht v20 o– 18i, 17i (16i), d2sa, d2a, v4 a; d5c, dac. Inner apical spines of hind tibiae longer than outer ones. Posterior margin of sixth abdominal tergite with an obtusely rounded median process; posterior margin of seventh abdominal tergite with long and wide median lobe, which posterior margin slightly concave in middle (Fig. 5 D–E). Cerci long, conical, apices acute. Subgenital plate longer than broad, posterior margin slightly projected, styli short and stout (Fig. 5 F–G).

Female. Unkown.

Coloration. Body brown. Eyes darkish, ocelli pale yellowish; frons and genae yellowish brown. Sternum and legs yellowish; hind femora with some light brown spots and stripes.

Measurement (mm). BL ♂ 20.6; PL ♂ 7.5; FFL ♂ 8.6; HFL ♂ 19.5; HTL ♂ 18.2; HBL ♂ 4.5.

Material examined. Holotype: male, Bawangling, Changjiang, Hainan, China, 27 May, 2014, coll. by Jiao Jiao.

Distribution. China (Hainan).

Discussion. The species is very similar to Vietnamese S. cattien and S. tatianae, but differs from the two by: posterior margin of male sixth abdominal tergite with an obtusely rounded median lobe, and the median process of seventh abdominal tergite wide with center of posterior margin concave (Fig. 5 D – E). In S. cattien, posterior margin of male sixth abdominal tergite slightly projected in the middle (Fig. 6 A), and the posterior margin of median process of seventh abdominal tergite obtusely rounded. In S. tatianae, posterior margin of male sixth abdominal tergite without any process, and the posterior margin of median process of seventh abdominal tergite straight (Fig. 6 D).

Etymology. Named after the type locality Hainan province, China.
