This dataset contains the digitized treatments in Plazi based on the original journal article Schmidt-Rhaesa, Andreas (2026): Record of deep-sea Nephasoma constricticervix (Sipuncula, Golfingiidae) from the Guinea Basin (South-East Atlantic). Evolutionary Systematics 10 (2): 375-381, DOI: 10.3897/evolsyst.10.210468
Abstract
Six specimens of Nephasoma constricticervix are reported from the Guinea Basin from 5141–5171 m depth, collected during the Diva II expedition. This species was reported earlier from this region as “ unpublished record ”. Most characteristic are the long introvert hooks (up to 123 µm in our specimens), which decrease in size posteriorly and a constriction between introvert and trunk. An SEM investigation of the hooks shows their fine structure and the presence of papillae associated with the hooks.
