The authors considered that all junior synonyms proposed for C. australiensis by Burton (1934) should need further taxonomic revision. Moreover, the genera [Psetalia] Gray, 1873 (nomem oblitum), [Labaria] Gray, 1873 (nomen oblitum) and Raphidotethya Burton, 1934 were included as synonyms of the genus Cinachyrella." 2018;"van Soest et al.

Further investigations will reveal if the five species from the C. schulzei- group can be synonymized or belong to separate and distinctive species."
