Hyalospheniidae is a group of testate amoebae and the sole family of the infraorder Hyalospheniformes.[4] Hyalospheniid testate amoebae are considered important bioindicators, which is why they are frequently used for environmental monitoring and their fossils are studied to investigate the paleoecology.[5]
The following cladogram illustrates the evolutionary relationships between all hyalospheniid genera found through phylogenetic analysis,[6] with the exception of Porosia, a genus excluded from the analysis that appears to be closely related to Certesella[7] and is therefore placed next to it in the cladogram.
HyalospheniidaeThe current taxonomy of the family recognizes 14 genera:[4][8]
