Lagenodifflugia epiouxi (Chardez, 1983) new comb.
Basionym: Pontigulasia epiouxi Chardez, 1983

Diagnosis: Shell elongate, circular in cross-section or very slightly compressed. The neck is separated from the main body through a very slight constriction: at this level, there is a rather thick diaphragm with a more or less central, oval or crescent-shaped aperture. Shell composed of quartz particles of different size and shape. Pseudostome circular with a rough edge..

Dimensions: Chardez (1984): Shell length 285-340 µm, width 165-190 µm; nucleus 50-55 µm. Neck 83-100 µm.

Ecology: Fresh water, organic sediment.

Remarks: Probably, this species is a synonym of L. vas.
