Figs. 3–4 View FIGURES 1 – 13. 1 – 2 , 23–31 View FIGURES 23 – 31
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 View FIGURES 1 – 13. 1 – 2 ). Vertex yellowish brown. Antennae and maxillary palpomeres yellowish brown ( Fig. 4 View FIGURES 1 – 13. 1 – 2 ). Pronotum yellowish brown, with blackish brown spots and stripes at disc, and lateral borders and posterior margin hyaline ( Figs. 3 View FIGURES 1 – 13. 1 – 2 , 25 View FIGURES 23 – 31 ). Tegmina pale yellowish brown, hind wings pale brown ( Fig. 3 View FIGURES 1 – 13. 1 – 2 ). 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 View FIGURES 1 – 13. 1 – 2 ).
Vertex with interocular space narrow, nearly equal to half of distance between antennal sockets ( Fig. 23 View FIGURES 23 – 31 ). The third maxillary palp slightly shorter than the fourth, but both distinctly longer than the fifth ( Fig. 24 View FIGURES 23 – 31 ). Pronotum nearly elliptical, anterior and hind margins more or less straight and truncate ( Figs. 3 View FIGURES 1 – 13. 1 – 2 , 25 View FIGURES 23 – 31 ). 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 View FIGURES 23 – 31 ). 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 View FIGURES 23 – 31 ). Front femur Type B3 ( Fig. 28 View FIGURES 23 – 31 ); 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 View FIGURES 23 – 31 ).
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 View FIGURES 23 – 31 ). 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 View FIGURES 23 – 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).
