<i>Neocucumis kilburni</i> sp. nov. (Echinodermata : Holothuroidea : Cucumariidae) from the east coast of South Africa, with a key to the genus <i>Neocucumis</i>

Abstract

A new dendrochirotid holothuroid, Neocucumis kilbumi, is described from waters 50 meters deep, off the southern coast of KwaZulu-Natal, South Africa. It appears quite close to N. watasei (Ohshima) and N. sordidatus (Sluiter), both from the West Pacific and to N. atlanticus (Ludwig & Heding) from the Atlantic Ocean and the Mediterranean Sea. It differs from the former in the nature of the calcareous ring and the disc and the spire of the body wall tables, from N. sordidatus in the completeness of its deposits and the number of polian vesicles and from N. atlanticus in the presence of handles to the quadrilocular table discs. The new species increases to ten the number of species now classified in the genus Neocucumis. A key to all the species is included.
