Revision of the Genera and Species Composition of Lower Centroheliozoa IFamily Heterophryidae POCHE

Abstract

A revision of the centroheliozoan family Heterophryidae on the base of the external envelope structure is performedThe genus Cienkowskya is shown to have no centroheliozoan affinities and is transferred from this group; it is a heliozoa incertae sedisThe genus Heterophrys is shown to be heterogeneousHfockii with a tangential orientation of organic spicules is transferred to the genus Sphaerastrum GREEFF, emend., while the other species with radial spicules remain in the genus HeterophrysA new species Hfebvre-chevalierae is describedEmended diagnoses for genera Heterophrys and Sphaerastrum and species Hmyriopoda, Hmarina and Sfockii and a key for the family Heterophryidae are suggested.
