Chelifera polonica Wagner and Niesiolowski, 1987 (Diptera: Empididae) is a rare empidid fly, originally described from the Gorce Mountains (Outer Western Carpathians, SE Poland) in 1987. The species has not been recorded there since then. In the present paper C. polonica is reported from two streams from the Bieszczady Mts. (Outer Eastern Carpathians). These two new records are the other known localities of the species in Poland and in Europe. The distribution of C. polonica is discussed. Photographs of the whole male and its genital structures are presented.
