The middle Villafranchian site (MN zone 17) near Varshets provided over 110 species of vertebrates, 51 of them avian species. That makes it the richest Tertiary site of that age in Europe. The paper describes a new falcon by a right half of the postacetabular part of the pelvis (holotype, No NMNHS 1642). Diagnose: a medium sized (between F. subbuteo and F. peregrinus) fossil species of g. Falco, differing by the sharp transition (turn) of crista iliaca dorsolateralis over the ala ischii (Fig. 1) and the rounded (oval), but not angular shape of the caudal edge of foramen ilioischiadicum. All sites of g. Falco up to now originate from SE Europe.
