Two new species of Stolus selenka (Echinodermata: Holothuroidea: Dendrochirotida: Phyllophoridae) from off the east coast of South Africa, with a revised key to the genus

Eleven specimens of dendrochirotid holothuroids, dredged from fairly deep waters (84-120 m) at several localities off the KwaZulu-Natal coast in South Africa, are here described as Stolus pseudoalbescens n.sp. with another three specimens of perhaps the same species referred to as S. cf. pseudoalbescens since they lack the tubercles of the new species and differ in some details of the calcareous ring and podial spicules. In addition, another new species based on a single minute specimen collected at 78 m, also from the KwaZulu-Natal coast, is described as S. dentatus n.sp. The description of these two species increases to four the number of Stolus spp. now known from South Africa: S. buccalis (Stimpson, 1856); S. kilberti (Rajpal & Thandar, 1999), S. pseudoalbescens n.sp. and S. dentatus n.sp.
