D e s c r i p t i o n. Head ( fig. 30 – 31 View Figs 30–38 ). Orbit projected above eye in profile only at level of orb s; 3 orb s, 3 fr s; frorb sta elongated in several rows, reclinate nearest to eye and proclinate nearest to frons; orbit wide and shining (frontal view); frontal carina absent; lunule slightly shining, high, rounded dorsally, with deep furrow; ocellar triangle as matt as frons, wide, with distinct contours; vibrissa and sbvb s are of the same length; maximum high of eye 4.8× as maximum high of gena; gena slightly acute ventrally; 1st flagellomere rounded (lateral view).

Wing ( fig. 34 View Figs 30–38 ) slightly yellowish, with all veins brown; costa reaching M 1; last section of CuA 1 0.85× as long as penultimate; costal sections 2–4 in the ratio of 3.87: 1.06: 1.00; calypter and fringe white, margin yellow. Wing length 2.7 mm in both sexes.

Mesonotum and scutellum slightly shining, blackish-grey (dorsal view); abdomen strongly shining, yellowish-green; 2 dc; ac in 8 irregular rows at level of 2nd dc; halters and legs dark brown.

Male terminalia ( figs 32, 33, 35, 36 View Figs 30–38 ). Epandrium covered with long hairs; inner surface of surstylus covered only with numerous short and small prensisetae; hypandrium V-shaped, with obtuse apex (ventral view); ejaculatory apodeme slightly longer than phallus; phallus 0.21 mm long; distiphallus complex elongated, oval and narrowing posteriorly (ventral view); mesophallus long, flattened apically; basiphallus typical for the genus.

Female terminalia ( figs 37 – 38 View Figs 30–38 ). Both spermathecae oval, of different size, dark brown, flattened basally; both spermathecae with collars; egg guide relatively wide, 4.5× as long as maximum width, acute apically; middle and ventral part of medial membrane covered with numerous small brown teeth; ventral seminal receptacle, left blade, proctiger and cerci as on fig. 38.

B i o n o m i c s. One generation was recorded in June. Host plant unknown, but probably the flies are associated with Centaurea jacea L., as six specimens were caught in thicket of this plant in a small meadow, where no other possible host plants were present. Other specimens were collected on motley grass meadows with Centaurea jacea L., too.

D i a g n o s i s. The new species is superficially similar, in having proclinate and reclinate frorb sta together, wide lunule with slight furrow and white calypter, to M. dettmeri Hering, 1933 , running to that species in the key by Papp, Černý (2015), but differing by the orbit slightly projecting above eye only at level of orb s (lateral view); last section of CuA 1> 0.75× (0.85×) as long as penultimate; margin yellow; mesonotum and scutellum slightly shining, blackish-grey (dorsal view); abdomen strongly shining, yellowish-green; inner surface of surstylus covered only with numerous short and small spines; setae on cerci short, whereas in M. dettmeri orbit projecting as narrow ring above eye (lateral view); last section of CuA 1 <0.75× (0.67×) as long as penultimate; margin pale brown; mesonotum “matt, faintly greenish or coppery, abdomen distinctly shining, variably coppery-greenish or bluish”; “inner surface of surstylus with group of denser and long setae on ventral margin and group numerous spines on inner surface” ( Papp, Černý, 2015); setae on cerci long.

E t y m o l o g y. The name reflects the locality (a thicket of meadow plants), where all the specimens were collected.
