Type material.

Holotype: ♂, CHINA: Yunnan, Pingbian County, Daweishan, 7 Aug 2014, Zheng-Xiang Zhou; Paratypes: 1♂, as paratypes Qiang Luo, 20 Aug 2017; 4♀♀, 8 Aug 2017, Hai-Yan Sun.

Diagnosis.

The salient features of the new species include the following: medioventral process of pygofer with two larger lateroapical processes, directed inward (Figure 33); and phallobase of aedeagus with right basal long lobe branched into two processes, apexes bent, directed inwards, left apical short lobe directed apically (Figs 35-36).

Description.

Measurements. Body length (from apex of vertex to tip of forewing): male 4.9- 5.1 mm (n = 2), female 5.0-5.3 mm (n = 4); forewing length: male 3.5-3.9 mm (n = 2), female 4.6-4.8 mm (n = 4).

Colouration.

Body with colour pattern (Figs 22-28) except the form of a broad irregular longitudinal dark brown band from base to apex of clavus (Figure 29), as same as M. luchunensis sp. n.

Head and thorax.

Ratio width of vertex at posterior margin to its length in midline 2.0 (Figure 26), anterior third produced before eyes. Ratio length of frons in midline to its maximum width 1.2, ratio maximum of width to width at apex 1.8 Ratio length of postclypeus in midline to length of frons 0.5 (Figure 27). Rostrum with ratio apical to subapical segment 1.5. Lateral lobes of pronotum with three short longitudinal carinae behind eye, ratio length in midline to length of vertex 0.8 (Figure 26). Mesonotum (Figure 26) in midline 5.5 times longer than pronotum, 2.5 times longer than pronotum and vertex combined. Forewing (Figure 29) with ratio of length to maximum width 3.0, vein R with subapical cell. Hindwing (Figure 30) with length to maximum width ratio of 2.0. Post-tibiae with a lateral spine in basal 1/5, spinal formula 7 –6– 6.

Male genitalia.

Anal segment in dorsal view (Figure 31) with ratio length to maximum width 1.2, basal margin roundly concave in middle, apical margin angularly convex in middle, anal style not exceeding apical margin of anal segment; in lateral view (Figure 32) with basal 2/3 broad, apical 1/3 slender as finger, roundly bent ventrally, lateral margin near middle with a strong spinous process, directed ventrally. Pygofer in lateral view (Figure 32) with posterior margin slightly sinuate. Medioventral process (Figure 33) short and broad, with two large lateroapical processes, apical margin truncate. Genital style (Figure 34) with apical margin roundly convex, widest part at apical 2/5, a twisted process rising from nearly basal 1/2 of dorsal margin, branched into three lobes. Aedeagus (Figs 35-36) asymmetrical, phallobase in ventral view (Figure 36) with three long lateral processes rising from apex, five long processes rising from base, with another single long irregular flaky bifurcation ventral processes rising from base. Phallic appendages straight with apical margin roundly convex, distinctly exceeding apical margin of phallobase.

Female genitalia.

Seventh abdominal sternum in ventral view (Figure 37) with posterior margin distinctly concave. Anal segment (Figs 38-39) in dorsal view with ratio of width to its maximum length 1.0, anal stylet distinctly exceeding apical margin of anal segment. Second valvula in ventral view (Figure 41), with ratio of width to its maximum length 1.2. Sclerite on entrance of bursa copulatrix in ventral view (Figure 42) prominent, T– shaped.

Etymology.

This specific name refers to the type locality, Pingbian, Yunnan Province, China.

Distribution.

China (Yunnan).

Remarks.

This species is similar to M. cervina (Fennah, 1956), but differs from the latter in: Medioventral process of pygofer with apical margin in the middle concave ( M. cervina with apical margin in the middle distinctly convex); phallobase of aedeagus with outermost left lateral processes with apical 1/2 hardly bent, directed apically ( M. cervina with outermost left lateral processes with apical 1/2 distinctly bent, directed inwards).
