Three new species of Saracenaria from the Lower Cretaceous of the Ust-Yenisei District are described. S. gerkei sp. nov. is recorded in the Valanginella tatarica, Recurvoides obskiensis Foraminiferal Zone (KF2, upper boreal Berriasian-Valanginian). S. vologochanensis sp. nov. and S. pjasinensis sp. nov. are characteristic of assemblages of the beds with Cribrostomoides infracretaceous, Cribrostomoides sinuosus (KF4, terminal Lower Valanginian-basal Hauterivian). Detailed comparisons of new species with other most closely similar morphotypes are provided
