Revisiting Asbestopluma (Asbestopluma) magnifica in the SW Atlantic: taxonomic amendments, new insights, and evidence for potential conspecificity with Asbestopluma (Asbestopluma) sarsensis
Published online by Cambridge University Press: 17 February 2025
Abstract
In the present study we update the distributional, bathymetric ranges and taxonomic characters of the carnivorous sponge Asbestopluma (Asbestopluma) magnifica Lopez, Bravo & Hajdu, 2011 providing new records for Argentinian jurisdictional waters in the SW Atlantic Ocean, including the Marine Protected Area Namuncurá/Burdwood Bank. The shallowest bathymetric range is now changed to the upper bathyal (289 m depth). We also amend the original description after re-examination of type materials, when markedly different micrometric values were observed for their subtylostyles and acanthotylostrongyles. We noticed a remarkable similarity between Asbestopluma (Asbestopluma) sarsensis Goodwin, Berman, Downey & Hendry, 2017 and A. (A.) magnifica and we suspect they may be synonymous, but we refrain from taking a formal decision pending revision of all materials reported for the younger taxon or a genetic analysis.
