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 .
