Body yellowish brown with blackish brown stripes and maculae (Fig. 7). Vertex pale yellow with a black brown band between eyes. Antennae yellowish brown with its apex blackish brown. Maxillary palpomeres yellowish brown (Fig. 8). Pronotum yellowish brown, scattered with blackish brown stripes and maculae (Figs. 7, 45). Tegmina yellowish brown, and hind wings nearly colorless and hyaline (Fig. 7). Legs yellowish brown with blackish brown spots at base of spines. Sterna yellowish, with black stripes along lateral margins of sterna; each segment with 1 small black spot between stripes. Styli pale white (Fig. 8).
Vertex with interocular space narrower than the distance between antennal sockets (Fig. 43). Third and fourth maxillary palpomeres approximately the same length, and both distinctly longer than the fifth (Fig. 44). Pronotum nearly elliptical, hind margin nearly straight and truncate (Figs. 7, 45). Both tegmina and hind wings fully developed, extending beyond abdomen. Tegmen with 6 radial sectors unbranched, 1 radial sector branched; M absent; CuA with 3 complete branches (Fig. 46). Hind wing with apex of anterior rami of radius slightly thickened; median vein simple or with a bifurcated branch; CuA with 1 complete branch (Fig. 47). Front femur Type B2 (Fig. 48); tarsi with pulvilli present, tarsal claws symmetrical and specialized, with minute denticles on ventral margins. Male with 1st and 7th abdominal terga unspecialized, 8th abdominal tergum specialized and with a group of setae at near posteromedian margin (Fig. 49).
Supra-anal plate symmetrical with hind margin slightly convex; right and left paraprocts simple and similar, sheet-like, obtuse at apex and each with 1 spiniform process at base (Fig. 50). Subgenital plate slightly asymmetrical, anterior and left margin distinctly concaved, and right margin obviously convex near the middle. Styli similar and rodlike. Inter-stylar margin more or less turned upwards, distance between styli wide and approximately 2 times wider than length of style (Fig. 51). Left phallomere small and irregular (Fig. 52); median phallomere slender and rodlike, robust at anterior and with a row of spines at posterior, accessory sclerite slender (Fig. 51); hooklike right phallomere thickened at anterior, apex of hook curved and acute (Fig. 53).
Material examined. Holotype: ♂, China, Hainan Prov., Baoting, Qixianling, 2 May 2013, coll. Gui Shunhua (SWU).
Paratypes: 4 ♂ 4♀, same data as holotype (SWU); 1 ♂, China, Fujian Prov., Zhangzhou, 12 May 1980, coll. Lin Wenchu (SWU).
Remarks. This species is similar to Margattea nimbata (Shelford) but differs by the following characters: 1) supra-anal plate with hind margin slightly convex, concave in M. nimbata; 2) median phallomere with a row of spines at posterior, a pair of spinelike sclerites in M. nimbata.
Etymology. The specific epithet is derived from the Latin “ spinosus ”, referring to the accessory sclerite of median phallomere with apex spinous.
Distribution. China (Hainan, Fujian).
