Testate amoebae are eukaryotic single-cell protozoa that move on pseudopods, have a shell and aperture, usually a few tens to several hundred µm in size. Testate amoebae live mainly in moist soils, swamps, ponds, lakes and freshwater bodies, rarely in brackish and marine environments.
The testate amoeba species Netzelia tuberspinifera (Hu, Shen and Gong, 1997) Gomaa et al., 2017 was firstly discovered and described as Difflugia tuberspinifera in 1997 in the Wujiang River (Guizhou province, China).
