Staurocalyptus is a genus of sponge. It was circumscribed in 1897 by Isao Ijima.[1]

Taxonomy

S. pleorhaphides

Ijima circumscribed Staurocalyptus as a genus in the family Rossellidae. His initial taxonomy included three newly described species and two transferred from Rhabdocalyptus.[1] Ijimi did not designate a type species; in 1967 V. M. Koltun designated Rhabdocalyptus dowlingi Lambe, 1893 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 Ijima, 1897.[2] However, as of 2017, WoRMS still classifies Staurocalyptus as a genus and follows Koltun's type species designation, not that of Tabachnick.[3]

Distribution

Its species are found in the Pacific Ocean, at a depth of 30–1,700 metres (98–5,577 ft).[2]

Species

As of 2017, WoRMS recognizes the following seventeen species:[3]
