"pentasteria" Ehrenberg, 1841, p.111,149. Holotype: not designated. NOW Actiniscus. Originally Dictyocha subgenus Actiniscus, subsequently (and now) Actiniscus, thirdly Gymnaster. Downie and Sarjeant (1965, p.82) retained this species in Actiniscus. 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.
