It was first published as Euryale sukaczeviiP.I. Dorof. by Pavel Ivanovich Dorofeev in 1959. [1] It has been proposed to move it to a separate genus PalaeoeuryaleP.I. Dorof., of which it is the type species, [4] as Palaeoeuryale sukaczevii(P.I. Dorof.) P.I. Dorof published by Pavel Ivanovich Dorofeev in 1972. [4] [5] Later it was proposed to move it to the genus PseudoeuryaleP.I. Dorof. as Pseudoeuryale sukaczevii(P.I. Dorof.) Doweld published by Alexander Borisovitch Doweld in 2022. [6] [7]
