*pentasterias (Ehrenberg, 1841, p.111,149) Ehrenberg, 1844a, p.68. Holotype: not designated. Originally Dictyocha subgenus Actiniscus (Appendix A), subsequently (and now) Actiniscus, thirdly Gymnaster. Downie and Sarjeant (1965, p.82) retained this species in Actiniscus. Illustrations of this species were provided by Ehrenberg (1854, pl.18, fig.61; pl.19, fig.45; pl.20, fig.48; pl 33 (XVII), fig.1 and pl.33 (XVIII), fig.1. Dumitrică (1973, p.822) considered Dictyocha (now Actiniscus) elegans and Dictyocha (now Actiniscus) sirius to be questionable taxonomic junior synonyms of this species. Age: Pliocene.
