hyalospheniidae hyalospheniidae hyalospheniidae is a group of testate amoebae and the sole family of the infraorder hyalospheniformes. 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. hyalospheniidae hyalosphenia papilio scientific classification domain: eukaryota phylum: amoebozoa class: tubulinea order: arcellinida suborder: glutinoconcha infraorder: hyalospheniformeslahr et al. 2019 family: hyalospheniidaeschulze, 1877 emend. kosakyan & lara 2014 genera 14 (see text) synonyms nebelidae taranek 1882 phylogeny the following cladogram illustrates the evolutionary relationships between all hyalospheniid genera found through phylogenetic analysis, with the exception of porosia, a genus excluded from the analysis that appears to be closely related to certesella and is therefore placed next to it in the cladogram. hyalospheniidae nebela quadrulella certesella porosia longinebela planocarina alabasta hyalosphenia cornutheca mrabella gibbocarina alocodera padaungiella classificaton the current taxonomy of the family recognizes 14 genera: infraorder hyalospheniformes lahr et al. 2019 family hyalospheniidae schulze 1877 emend. kosakyan & lara 2014 alabasta duckert et al., 2018 alocodera jung, 1942 apodera loeblich & tappan, 1961 certesella loeblich & tappan, 1961 cornutheca kosakyan et al., 2016 gibbocarina kosakyan et al., 2016 hyalosphenia stein, 1859 longinebela kosakyan et al., 2016 mrabella kosakyan et al., 2016 nebela leidy, 1874 padaungiella lara et todorov, 2012 planocarina kosakyan et al., 2016 porosia jung, 1942 quadrulella cockerell, 1909
