Abstract
A new species of the conodont genus Palmatolepis—Pa. abramovae sp. nov. is described from the Makarovo Regional Substage of the Famennian Stage based on materials from four sections of the western slope of the South Urals (Bolshaya Barma, Akkyr, Ryauzyak, and Kuk-Karauk). The paper presents ontogenetic series of the described species and suggests its possible phylogenetic relationships. Pa. abramovae sp. nov. is a characteristic species of the Upper triangularis Zone.
