L. parva, after Thomas and Gauthier-Lièvre, 1959

Lesquereusia parva (Thomas et Gauthier-Lièvre, 1959)

Diagnosis: This species was described as a variety of L. mimetica Penard 1911. It differs from that species by its much smaller size. It differs from L. modesta by the shape of its neck, which is not partly separated from the main body.

Dimensions: Length 133-200 µm; width 107-120 µm; thickness c. 85 µm; pseudostome 30-40 µm.

Ecology: Freshwater. Rivers and marshes. France, Africa (Thomas et Gauthier-Lièvre, 1959).
