Staurocalyptus
Staurocalyptus is a genus of sponge. It was circumscribed in 1897 by Isao Ijima.
Taxonomy
Ijima circumscribed Staurocalyptus as a genus in the family Rossellidae. His initial taxonomy included three newly described species and two transferred from Rhabdocalyptus. Ijimi did not designate a type species; in 1967 V. M. Koltun designated Rhabdocalyptus dowlingi as the type species. A 2002 revision of Rossellidae by K. R. Tabachnick demoted Staurocalyptus to be a subgenus of Acanthascus and designated a new type species: Staurocalyptus glaber. However, as of 2017, WoRMS still classifies Staurocalyptus as a genus and follows Koltun's type species designation, not that of Tabachnick.Distribution
