Euglypha vanoyei  (Van Oye, 1958) Decloitre, 1962
Basionym: Euglypha curvata  Van Oye, 1958 (name preoccupied by Perty)

Diagnosis: Distinguished from all other Euglypha species by two very visible characteristics: the first is its curvature which is noticeable at first sight, the second is its flattened base visible as soon as it is not absolutely in profile on one side. It could be assimilated to a curved E. compressa f. glabra if it did not have a flattened base.

Dimensions: Shell length 70 µm; width 47 µm; aperture diameter 12 µm.

Habitat: Fresh water, marshes. First found in Congo, 1948, at 3,000 m asl.
