I found two cells, size about 125 µm when ovoid, with an organic-walled membranous test and a single terminal aperture. The test is hyaline and colorless, flexible, smooth and delicate. From a long peduncle some long branching and anastomosing granuloreticulopodia radiate. Cytoplasm in continuous streaming, with many small granules, bi-refringent yellowish rod-shaped crystals and food vacuoles. It was not possible to detect any nuclei but there were no large nuclei as described for Lieberkuehnia paludosa by Penard, 1907.
Measurements: 127 µm (n=1)
Ecology: Freshwater; on submerged rock at the base of the dike along the northern part Gooimeer (Lake Gooi), the Netherlands, May 2020 (52°18’17.7″N 5°18’51.6″E).
Remarks: I found only two specimens. One was lost when isolated, the other was sequenced by Maria Holzmann with the result that it belongs to Group 4 and is related to genera Lieberkuenia and Claparedellus. However, it will be described as a new species with a new genus. The name “Lachmanni” is a worktitle.
