Distephanus sirius Appendix A

"sirius" (Ehrenberg, 1841, p.150) Haeckel (according to Schütt, 1891, p.20).  Holotype: not designated.  NOW Actiniscus.  Originally Dictyocha subgenus Actiniscus, subsequently (and now) Actiniscus, thirdly Distephanus (name not validly published; Appendix A), fourthly Gymnaster.  In his synonymy list for this species, Schütt (1891) indicated that the name Distephanus sirius was cited by Haeckel (date not specified).  Dumitrică (1973, p.822) considered Dictyocha (now Actiniscus) pentasterius to be the questionable taxonomic senior synonym of this species.  N.I.A.  Age: Miocene.
