Male. Differing from M. atrata as follows: Head with dark grayish pruinosity; narrow shining black marking on inner margin of fronto-orbital plate extending and widening below parafacial to level of base of arista; occiput shining black. Frons at the narrowest point about 4 times as wide as base of arista; parafacial nearly parallel-sided, about 1.5 times (about 1.3 times in profile) as wide as 1st flagellomere at middle height; lower margin of face weakly warped forward; gena about 1/3 as high as (about 2/ 7 in profile) eye height; inner vertical seta about 2/3 as long as eye height; 15–18 fine frontal setae; facial ridge with 2–3 long and some short and fine setae on lower 1/4; 4–6 long and strong subvibrissal setae; base of antenna nearly level with lower 1/4 of eye height in profile. Thorax shining black in ground color, with very thin grayish pruinosity on postpronotal lobe and 2 longitudinal vittae on presutural area of scutum; 2 presutural acrostichal setae; 3 presutural dorsocentral setae; 3 katepisternal setae, lower seta rather fine; scutellum with long erect hairs, discal setae not distinguishable among them, long hairs nearly as long as scutellum. Wing rather well tinged with brown basally; relative lengths of costal sectors 2nd, 3rd and 4th approximately as 2:6.5:3.5; vein M nearly right-angled, from dm-cu crossvein to its bend about 1.5 times distance between the bend and wing margin, with short appendix.

Male terminalia: Fifth sternite with short hairs on apical portion; epandrium with 4 pairs of strong setae; surstylus in lateral view weakly constricted near basal 1/4, weakly rounded to apex; cerci in dorsal view widely separated on basal 1/2, close together at middle and narrowly separated on apical 1/2, in lateral view broad at base and curved ventrally, apex pointed.

Body length: 6.6 mm.
