De Smet W. H. & Verolet M. 2009. — On two new species of Proales from France, with reallocation of Dicranophorus liepolti Donner, 1964 and D. secretus Donner, 1951 (Rotifera, Monogononta). Zoosystema 31 (4): 959-973.

Two new species of rotifer, Proales ardechensis n. sp. and P. laticauda n. sp. (Monogononta, Proalidae) from the Ardèche, France, are described and illustrated. Proales ardechensis n. sp. is readily distinguished from its congeners by the stout foot composed of 4 pseudosegments of which the penultimate one bears an antenna at its posterior margin dorsally, and the malleate trophi bearing characteristic hook-shaped alulae. Proales laticauda n. sp. is characterized by its broad and stout truncate tail almost overlying the foot, and its small and slender basally swollen toes. Based on the trophi morphology studied by scanning electron microscopy Dicranophorus liepolti Donner, 1964 is reallocated to the genus Encentrum, and D. secretus Donner, 1951 is placed in the genus Aspelta.
