Description. Male: Overall length including tegmen (14.3–16.1mm), pronotum length × width (2.3–2.6×3.6–4.0mm), tegmen length (12.0– 12.7mm). Maxillary three terminal segments (0.43/0.62–0.72/ 0.42–0.47mm). Legs: fore trochanter (0.41mm), femur (2.18mm), tibia (1.60mm), tarsus (1.71mm: 0.94/0.20/0.17/ 0.06/ 0.35mm); mid trochanter (0.55–0.64mm), femur (3.05–3.09mm), tibia (2.85–2.99mm), tarsus (2.16–2.5mm: 1.16–1.30/0.37–0.40/0.20/0.10–0.18/ 0.22–0.32mm); hind trochanter (0.64mm), femur (3.49mm), tibia (5.22mm), tarsus (none).
Body yellowish brown (Fig. 3). Vertex yellowish brown. Antennae and maxillary palpomeres yellowish brown (Fig. 4). Pronotum yellowish brown, with blackish brown spots and stripes at disc, and lateral borders and posterior margin hyaline (Figs. 3, 25). Tegmina pale yellowish brown, hind wings pale brown (Fig. 3). Legs yellowish brown, with black brown spots at base of spines. Sterna yellowish with black stripes along lateral margins, and sparsely scattered with black maculae; each segment with 1 small black spot between stripes. Styli yellowish brown (Fig. 4).
Vertex with interocular space narrow, nearly equal to half of distance between antennal sockets (Fig. 23). The third maxillary palp slightly shorter than the fourth, but both distinctly longer than the fifth (Fig. 24). Pronotum nearly elliptical, anterior and hind margins more or less straight and truncate (Figs. 3, 25). Both tegmina and hind wings fully developed and extending beyond abdomen. Tegmen with 11 radial sectors unbranched, 3 with branch, one of which bifurcated at apical part; M absent; CuA with 6 branches, one of them bifurcated (Fig. 26). Hind wing with apex of anterior rami of radius clubbed or thickened; median vein simple; CuA with 3 complete branches, one of the second divisions further branched (Fig. 27). Front femur Type B3 (Fig. 28); tarsomeres 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 near posteromedian margin (Fig. 29).
Supra-anal plate symmetrical, with hind margin produced and rounded; right and left paraprocts simple and similar, sheet-like, obtuse at apex and each with 1 spiniform process at base (Fig. 30). Subgenital plate slightly symmetrical, anterior margin slightly curved inwards at middle, lateral margins slightly produced and rounded, with posterior lateral angles obtuse; styli symmetrical and nearly conical; inter-stylar margin nearly straight and distinctly concave at base of styli. Left phallomere small with spiniform processes; median phallomere slender and rodlike, obtuse at anterior and posterior, and with a row of spines situated at membrane apically; hooklike right phallomere with apex slightly acute, spine-like, and apex without preapical incision (Fig. 31).
Material examined. Holotype: ♂, China, Hainan Prov., Jianfengling, 4 December 1981, coll. Lin Youdong (SWU).
Paratype: 1 ♂, China, Hainan Prov., Jianfengling, 3 July 1981, coll. Zhang Junshan (SWU).
Remarks. This species resembles Margattea trispinosa (Bey-Bienko), but differs from the latter by the following: 1) inter-stylar margin nearly straight and truncate, the latter distinctly produced and curved; 2) middle phallomere with a row of spines near posterior, the latter with 3 stout spiniform processes at posterior.
Etymology. The specific epithet is derived from Latin word “ angustus ”, referring to vertex with interocular space narrow.
Distribution. China (Hainan).
