Schejter,l.; Cristobo, J.; Ríos, P. (2019) Coelosphaera (Coelosphaera) koltuni sp. nov. (Porifera: Demospongiae): a new species from South Orkney Islands, Antarctica. Marine Biodiversity.
In this work, we describe a new sponge species belonging to the genus Coelosphaera Thomson, 1873. It was collected during an Argentinean Summer Antarctic Research Cruise onboard the Research Vessel Puerto Deseado in March 2014, near South Orkney Islands (Antarctica), 60° 53' S 42° 35' W, 487-m depth.Coelosphaera (Coelosphaera) koltuni sp. nov. is a globular, fistular and hollowshaped sponge, with significantly larger megascleres (almost twice the length) than other Antarctic and New Zealand Coelosphaera species. We provide comparative data of all the described Coelosphaera species, especially those from nearby regions.
