I found this species in a sample from a small pond in the moor of Cayan near Pont d’Espagne, Cauterets, French Pyrenees, 2021. There were 12 shells, 147-565 µm long. This species differs from Lacogromia cassipara by its smaller aperture. As all cells were dead and their tests empty, I have no additional information about nuclei etc.. It seems to be an undescribed species.
