DESCRIPTION. FEMALE. Body length 3.1-4.3 mm, fore wing length 2.9-3.5 mm. Head. Antenna filiform with 26-28 segments, densely setose, length of distal segments 10-12 about equal to its width, other segments longer than width. Head rounded behind eyes; eye length about 3 times temple length (dorsal view). Ocelli medial, Od: POL: OOL = 3: 5: 5. Eyes convergent below, 1.3-1.4 times as high as broad. Frons without median tubercle, weakly concave. Malar space 2 times basal mandible width. Minimum width of face equal to its median height. Tentorial pits small but distinct, distance between pits about 4 times distance from pit to eye. Clypeal suture distinct. Clypeus strongly convex, rarely punctured, with long hair. Clypeal lower margin rounded; clypeal width about 1.2 times its height, 0.8 times minimum face width. Mandible twisted.

Thorax length 1.6 times its height. Notauli distinct, crenulate; joined anterad scutellar sulcus. Prescutellar depression deep, with longitudinal medial carina, 0.8 times as long as scutellum. Scutellum convex, with carinae in anterior-lateral part. Sternauli wide, crenulate,

protruding in the whole length of mesopleuron. Propodeum convex, rugulose, without any distinct carinae.

Wings. Fore wing: metacarpus 1.4 times as long as pterostigma. Radial vein arising somewhat after middle of pterostigma. Proximal part of medial vein lack. Second radiomedial cell strongly narrowed anterad. First abscissa: second abscissa of radial vein = 3: 5, third abscissa straight. Recurrent vein antefurcal. Nervulus postfurcal, distance from it to basal vein equal to nervulus length. Hind wing: second abscissa of mediocubital vein 1.2 times nervellus and 0.7 times basal vein. Legs. Hind femur 6-7 times as long as wide. Tarsal claws without lobe or tooth.

Abdomen. First tergite 2.1-2.2 times as long as its apical width, longitudinally striated; vental borders not joined. First tergite with deep dorsope in basal third. Spiracle tubercles of first tergite almost indistinct, located before middle. Second and the other tergites smooth. Ovipositor sheath 2.5-3.0 times as long as first tergite.

Colour various. Usually body, except light yellowish face, clypeus, mandible, palpi, legs without tarsi and second tergite of abdomen dark; rarely reddish or yellowish. Veins of wings brown, pterostigma yellow, with dark central patch.

MALE unknown.

DISCUSSION. This new species is closely related to M. tabidus Wesmael, 1835 and M. affinis Wesmael, 1835 , but easily differs by absence of proximal part of medial vein and by small size.

DISTRIBUTION. Belarus.
