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.
