Maxillary three terminal segments (0.52–0.55/0.48–0.55/ 0.43–0.45mm). Legs: fore trochanter (0.36–0.59mm), femur (1.83–2.00mm), tibia (1.17–1.28mm), tarsus (1.44mm: 0.72/0.18/0.13/0.12/ 0.29mm); mid trochanter (0.58–0.69mm), femur (2.31–2.55mm), tibia (1.92–2.1mm), tarsus (1.64–1.94mm: 0.91–0.92/0.28–0.30/0.14–0.17/0.10–0.20/ 0.21–0.26mm); hind trochanter (0.67mm), femur (2.86–3.09mm), tibia (3.85mm), tarsus (none).

Body blackish brown (Fig. 9). Face reddish brown, vertex dark reddish brown without mark or stripe. Maxillary palpomeres blackish brown (Fig. 10). Pronotum with disc blackish brown, anterior and posterior margins blackish brown, lateral borders nearly hyaline and slightly pale brown (Figs. 9, 56). Tegmina and hind wings yellowish brown (Fig. 9). Legs blackish brown. Sterna blackish brown. Styli white (Fig. 10).

Vertex with interocular space approximately equal to distance between antennal sockets (Fig. 54). Third and fourth maxillary palpomeres approximately same length, and both distinctly longer than the fifth (Fig. 55). Pronotum nearly elliptical, anterior margin straight and truncate, hind margin slightly produced at middle, disc with nearly rounded mark (Figs. 9, 56). Both tegmina and hind wings fully developed, extending beyond abdomen. Tegmen with 7 radial sectors unbranched, 1 radial sector branched and one of the second division further branched; M absent; CuA with 3 complete branches, two of them branched (Fig. 57). Hind wing with apex of anterior rami of radius clubbed or thickened; median vein unbranched; CuA with 3 complete branches and one of them bifurcated at apical part (Fig. 58). Front femur Type B2 (Fig. 59); tarsomeres with pulvilli present, tarsal claws symmetrical and rudimentary, with inconspicuous denticles on ventral margins. Male with 1st to 7th abdominal terga unspecialized, 8th abdominal tergum specialized and with a group of setae near posteromedian margin (Fig. 60).

Supra-anal plate symmetrical, and nearly triangular, with hind margin concave at middle; right and left paraprocts simple and similar, sheet-like, obtuse at apex and each with 1 spiniform process near base (Fig. 61). Subgenital plate slightly asymmetrical, anterior margin slightly concave at middle, left lateral margin more or less convex at middle, right lateral margin nearly straight. Styli dissimilar, cone-like. Inter-stylar margin convex, length of styli approximately equal to distance between styli (Fig. 62). Left phallomere somewhat large and complicated, with spinelike processes, one of which has apex with a group of setae (Fig. 63); median phallomere slender and rodlike, obtuse at posterior, accessory median sclerite arched and inflated at both apex, left apex brush-shaped; hooklike right phallomere acute and incurved at apex (Fig. 62).

Material examined. Holotype: ♂, China, Yunnan Prov., Xishuangbanna, Damenglong, 650m, 29 July 1958, coll. Zheng Leyi (SWU).

Paratypes: 1 ♂, China, Yunnan Prov., Xishuangbanna, Damenglong, 650m, 24 July 1958, coll. Zhang Yiran (SWU); 1 ♂, China, Yunnan Prov., Xishuangbanna, Damenglong, 650m, 7 May 1958, coll. Chen Zhizi (SWU).

Remarks. This species resembles M. limbata, but it can be distinguished by: 1) accessory sclerite of middle phallomere arched without any sclerite, the latter with 1 nearly triangular and brush-shaped sclerite; 2) left lateral margin of subgenital plate more or less convex in the middle, the latter slightly concave; 3) two styli stout, but the latter slender.

Etymology. The Latin word “ pseudolimbata ” refers to the superficial resemblance of this species to Margattea limbata Bey-Bienko.

Distribution. China (Yunnan).
