Astroblastocystis nom. nov. - a new replacement name for Blastocystis Jaekel, 1918 (Echinodermata, Parablastoidea).

The generic name Blastocystis has been proposed at least twice for different organisms for which nomenclature is governed by the International Code of Zoological Nomenclature. Blastocystis Jaekel, 1918, is a junior homonym of the generic name Blastocystis Alexeieff, 1911. We propose the following Astroblastocystis nom. nov. as a new replacement name (neonym) for Blastocystis Jaekel, 1918.
