( Figs. 8-9 ) Type material. HOLOTYPE: ♁, SLOVAKIA: Pribylina (68-6984), 13.vii. 1975, 900 m a.s.l., R. Rozkošný leg. PARATYPE: ♁, SLOVAKIA: Vysoké Tatry Mts., Bielovodská dolina valley (67-6886), 16.vii.1975, 1000 m a.s.l., R. Rozkošný leg. (all coll. Šifner).

Head. Posterior portion dark brown, rest yellowish brown and whitish dusted, antennae including scape and pedicel yellow to yellowish red, arista bare, black and basally thickened. Vibrissal callus distinct, with 3-4 vibrissae together with 3-5 very short bristles, palpi yellow and slightly enlarged. Genae and lower part of head ‘bearded’ with long and very fine hairs.

Thorax. Acrostichal bristles indistinct, two pairs of scutellar bristles of equal size, katepisternum bare, other chaetotaxy standard, wings darkened, all veins dark.

Abdomen. Sternite 3 rectangular, slightly broadened caudally with small projection, sternite 4 more or less square with distinct incision proximally, both without distinct bristles. Sternite 5 with short lobes arcuately curved inwards, with dense very short bristles medially ( Fig. 8 ), praegonite straight, broad and acutely pointed, beak-shaped, without bristles ( Fig. 9 ).

Female unknown.

Differential diagnosis. Microprosopa ozerovi sp. nov. differs from the related M. hoberlandti Šifner, 1981 , in the following characters: M. ozerovi sp. nov. – bristles between lobes of abdominal sternite 5 present, incision of abdominal sternite 4 distinct, praegonite beakshaped ( Figs. 8-9 ); M. hoberlandti – bristles between lobes of abdominal sternite 5 missing, abdominal sternite 4 oval, praegonite with two apical bristles ( ŠIFNER 1981).

Etymology. This species is dedicated to my colleague and eminent Russian dipterologist Andrey L. Ozerov (Zoological Museum of the Lomonosov State University, Moscow, Russia).

Distribution. Northern Slovakia.
