DESCRIPTION. FEMALE. Body length 3.5-4.3 mm, fore wing length 3.0- 3.6 mm. Head. Antenna with 23-25 segments, densely setose, the length of distal segments 10-12 about equal to its width (in far-eastern specimens the length somewhat larger than width), other segments longer than width. Antenna filiform, slightly thickened from segment 3 to apical part. Head strongly constricted behind eyes, generally not rounded; eye length about 2.5 times temple length (dorsal view). Ocelli small, Od: POL = 1: 2. Eyes convergent below, 1.3-1.4 times as high as broad. Frons without median tubercle. Malar space very short. Minimum width of face 1.6-1.7 times its median height, all face with punctures and moderately long light hairs. Tentorial pits distinct, medium size, distance between pits 5 times distance from pit to eye; diameter of pit somewhat smaller distance from pit to eye. Clypeus smooth, weakly convex, rarely punctured, its lower margin hardly and widely protruding in lobe; clypeal width about 2 times its height, 1.2 times minimum width of face. Mandible not twisted, its apical width 0.5 times basal width.

Thorax length 1.6 times its height. Middle part of mesoscutum delicately punctures, densely setose with small hairs. Notauli distinct, crenulate; mesonotum with a weakly rugulose patch before scutellar sulcus. Prescutellar depression with medial carina, puctate,

0.6 times as long as scuttelum. Scutellum convex, with carinae in anterior-lateral part, delicately rarely punctate. Sternauli moderately wide, crenulate, protuding in the whole length of mesopleuron. Propodeum convex, rugulose, with central longitudinal carina in proximal part.

Wings. Fore wing: radial cell weakly shortened. Metacarpus 1.5 times as long as pterostigma. Radial vein arising somewhat after middle of pterostigma. Second radiomedial cell distinctly narrowed anterad. First abscissa: second abscissa of radial vein = 5: 6, third abscissa straight. Recurrent vein interstitial. Nervulus postfurcal, distance from it to basal vein weakly shorter than nervulus length. Hind wing: second abscissa of mediocubital vein 1.2 times nervellus and 0.8 times basal vein. Legs. Hind femur 4-4.5 times as long as wide. Tarsal claws without lobe or tooth.

Abdomen. First tergite 1.8-1.9 times as long as its apical width, rugose-punctate medially and longitudinally striated laterally; vental borders not joined. Spiracle tubercles of first tergite weak but distinct, located after middle. Second and the other tergites smooth. Ovipositor sheath 1.6-1.9 times as long as first tergite.

Colour. Thorax and first tergite dark; head, rest of abdomen and all tarsi reddish (brown reddish); pterostigma, except basal quarter, brown; antenna and hind femur red yellowish; clypeus, palpi, rest part of legs, most of vein and basal part of pterostigma yellow.

MALE unknown.

DISCUSSION. This new species is closely related to M. profligator (Haliday, 1835) , but differs by more convergent eyes, by narrow face, by short and robust antenna.

DISTRIBUTION. Russia (Kamchatka, Primorskii krai), Belarus.

ETYMOLOGY. The specific name dedicates to my wife.
