Vidrinatax is intermediate in morphology between the subgenus Pentatax Thor 1922 and Causeyatax Vidrine 1994. Two new species, U. agilex sp. nov. and U. brevipedalis sp. nov., in the genus Unionicola, are described from freshwater Bivalves, Anodonta woodiana woodiana (Lea, 1834) (Bivalvia: Unionidae), which belong to subgenus Vidrinatax and Vietsatax Uchida and Imamura 1938 respectively.
