Description
Summary:Five new Antarctic species and four new genera of dendrochirote holothurians are described: Caespitugo diversipes gen. et sp.n., Caespitugo citriformis gen. et sp.n., Microchoerus splendidus gen. et sp.n. (all Cucumariidae), Crucella hystirix gen. et sp.n. (Paracucumidae), and Echinopsolus acanthocola gen. et sp.n. (Psolidae). To include Crucella in the Paracucumidae a minor change of the family diagnosis was necessary. This change is discussed. The species were caught on the continental shelf of the southern and eastern Weddell Sea. mainly in depths between 200 and 650m. Their systematic status within their families as well as relationships to representatives of other familes are discussed.
