Figs. 9–10 View FIGURES 1 – 13. 1 – 2 , 54–63 View FIGURES 54 – 63

Description. Male: Overall length including tegmen (10.5–11.2mm). Pronotum length × width (2.5× 3.8mm). Tegmen length (8.6–9.4mm). 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 View FIGURES 1 – 13. 1 – 2 ). Face reddish brown, vertex dark reddish brown without mark or stripe. Maxillary palpomeres blackish brown ( Fig. 10 View FIGURES 1 – 13. 1 – 2 ). Pronotum with disc blackish brown, anterior and posterior margins blackish brown, lateral borders nearly hyaline and slightly pale brown ( Figs. 9 View FIGURES 1 – 13. 1 – 2 , 56 View FIGURES 54 – 63 ). Tegmina and hind wings yellowish brown ( Fig. 9 View FIGURES 1 – 13. 1 – 2 ). Legs blackish brown. Sterna blackish brown. Styli white ( Fig. 10 View FIGURES 1 – 13. 1 – 2 ).

Vertex with interocular space approximately equal to distance between antennal sockets ( Fig. 54 View FIGURES 54 – 63 ). Third and fourth maxillary palpomeres approximately same length, and both distinctly longer than the fifth ( Fig. 55 View FIGURES 54 – 63 ). Pronotum nearly elliptical, anterior margin straight and truncate, hind margin slightly produced at middle, disc with nearly rounded mark ( Figs. 9 View FIGURES 1 – 13. 1 – 2 , 56 View FIGURES 54 – 63 ). 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 View FIGURES 54 – 63 ). 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 View FIGURES 54 – 63 ). Front femur Type B2 ( Fig. 59 View FIGURES 54 – 63 ); 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 View FIGURES 54 – 63 ).

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 View FIGURES 54 – 63 ). 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 View FIGURES 54 – 63 ). Left phallomere somewhat large and complicated, with spinelike processes, one of which has apex with a group of setae ( Fig. 63 View FIGURES 54 – 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 View FIGURES 54 – 63 ).

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.
