Abstract
A monographic description of representatives of the genus Parrelloides from the Upper Cretaceous of West Siberia (Campanian and Maastrichtian) has been performed. The established species of this genus, including two new ones, P. aquilonius and P. variabilis, are described. The stratigraphic range of the genus has been extended. The generic assignments of P. sibiricus (Neckaja) and P. proprius (Podobina) are revised. The Maastrichtian species P. aquilonius sp. nov. and P. variabilis sp. nov. occurred in the northern part of the West Siberian basin, P. sibiricus (Neckaja) in the central and southern parts, and P. proprius (Podobina) in the southern part.
