Limnogromia sinensis Siemensma et al., 2017
Diagnosis: Test cilindrical, agglutinated, chitinoid, encrusted with a large number of extremely small silicous xenosomes; pseudostome pliable and flexible, neck can bend very strongly. Multinucleate, up to 200 nuclei; nuclei very small, usually spherical, but also ovoid, with pieces of nucleolar material laying close to the nuclear membrane.
Dimensions: 235-411 µm long (mean 345 µm) and 65-75 µm broad (n-11); nuclei, 6-8 6.0-8.2 µm in diameter.
Ecology: Siemensma found 11 specimens in a sample from sediment of a shallow pond in the city of Yangshuo, China (2015). One specimen which he compressed till the plasm came out of the shell, contained up to 150 nuclei, 6.0-8.2 µm in diameter.
Observed food: diatoms, blue algae.
