Lesquereusia bispiralis
L. bispiralis, after Thomas and Gauthier-Lièvre, 1959

Lesquereusia bispiralis Thomas et Gauthier-Lièvre, 1959

Diagnosis: Neck with two septa. The neck is not cylindrical or conical, but abruptly bent, which causes a change in its direction: whereas at the beginning it followed the direction of the winding of the test, it is raised at an right angle, which gives it a distinctive and unusual appearance. The test is covered with quartz particles.

Dimensions: Length 300 µm; Width 170 µm; pseudostome 50 µm.

Ecology: Freshwater. Africa.
