Description. Male: Overall length including tegmen (16.1–16.8mm); pronotum length×width (2.6–3.0mm× 3.8–4.2mm); tegmen length (13.9–14.3mm). Maxillary three terminal segments (0.56–0.74/ 0.62–0.71/ 0.44–0.49mm). Legs: fore trochanter (0.15–0.16mm), femur (2.06–2.31mm), tibia (1.65–1.73mm), tarsus (2.03mm: 1.19/0.29/0.14/0.12/ 0.29mm); mid trochanter (0.15–0.31mm), femur (2.89–3.10mm), tibia (2.59–3.00mm), tarsus (2.15mm: 1.22/0.30/0.18/0.10/ 0.35mm); hind trochanter (0.27–0.51mm), femur (3.01–3.40mm), tibia (4.52–4.7mm), tarsus (none).
Body yellowish brown with blackish brown stripes and spots (Fig. 5). Face yellowish brown, with black maculae. Vertex pale yellow with two dark brown triangle-like maculae between eyes, link up in the middle. Antennae and maxillary palpomeres yellowish brown (Fig. 6). Pronotum yellowish brown, scattered with blackish brown stripes and spots (Figs 5, 34). Tegmina yellowish brown, and hind wings nearly hyaline (Fig. 5). Legs yellowish brown with blackish brown spots at base of spines. Sterna yellowish brown, each segment with 1 small black spot between stripes. Styli yellowish brown (Fig. 6).
Vertex with interocular space narrower than the distance between antennal sockets (Fig. 32). Third and fourth maxillary palpomeres approximately the same length, and both distinctly longer than the fifth (Fig. 33). Pronotum nearly elliptical, hind margin nearly straight and truncate (Figs. 5, 34). Both tegmina and hind wings full developed, extending beyond abdomen. Tegmen with 5 radial sectors unbranched, 3 with branch, one of which is bifurcated at apical part; M absent; CuA with 6 branches, one of the second divisions further branched (Fig. 35). Hind wing with apex of anterior rami of radius slightly thickened; median vein straight and unbranched; CuA with 5 complete branches and the second branch with sub-branch (Fig. 36). Front femur Type B3 (Fig. 37); 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 near posteromedian margin (Fig. 38).
Supra-anal plate symmetrical with hind margin slightly produced; right and left paraprocts simple and similar, sheet-like, obtuse at apex and each with 1 spiniform process at base (Fig. 39). Subgenital plate symmetrical, anterior margin distinctly concave in the middle, left and right margins both convex at the near anterior margin, and hind margin not produced. Styli similar and rodlike; inter-stylar margin strongly produced, whose lateral sides upturned and scattered with spines (Fig. 40). Left phallomere small and irregular (Fig. 41); median phallomere rodlike, hook-like at posterior and with a row of spines near distal, accessory sclerite arclike and slender (Fig. 40); hooklike right phallomere thickened at anterior, apex of hook curved and acute (Fig. 42).
Material examined. Holotype: ♂, China, Guizhou Prov., Zunyi, Suiyang, Kuankuoshui Nature Reserve, 16 August 2010, coll. Wu Keliang (SWU).
Paratypes: 2 ♂, same data as holotype (SWU).
Remarks. The species is similar to Margattea furcata Liu and Zhou, but differs from the latter in the following characteristics: 1) cubitus vein with 5 complete branches, the latter with 4 branches; 2) inter-stylar margin produced, with lateral sides upturned and scattered with spines, the latter strongly produced and reflexed into one bifurcated process; 3) median phallomere with one spine-shaped sclerite at posterior, the latter with one brushshaped sclerite at posterior.
Etymology. The specific epithet is derived from Latin word “ flexus ”, referring to both sides of inter-stylar margin flexing upwards.
Distribution. China (Guizhou).
