T'he new spirolegoceratid genus Pseudosverdrupites with the type species P. budnikovi sp. nov., and two spe-
cies, Sverdrupites harkeri (Ruzh.) and S. baraensis sp. nov., are described from the early Late Permian (Road-
ian) of northeastern Russia.  Based on morphogenetic analysis, phylogenetic relationships among the genera are
considered, and a new phylogenetic scheme of the family Spirolegoceratidae is proposed.

Key words: Ammonidea, new taxa, phylogeny, Late Permian, northeastern Russia.
