Sponge biodiversity of Beauchêne and the Sea Lion Islands and south-east East Falkland, Falkland Islands, with a description of nine new species

  • Claire Goodwin (a1) (a2), Jennifer Jones (a1), Karen Neely (a3) (a4) and Paul Brickle (a3) (a5)

Sponge samples were taken by scuba diving from six sites around Sea Lion Island (Sea Lion, Sea Lion Easterly and Brandy Islands), three sites south-east of East Falkland (Motley Island, Green Island and Triste Island) and six sites around Beauchêne Island. Nine new species are described: Iophon roseum sp. nov., Clathria (Microciona) tenebrosa sp. nov., Clathria (Microciona) cheeki sp. nov., Hymedesmia (Hymedesmia) laptikhovskyi sp. nov., Hymedesmia (Hymedesmia) croftsae sp. nov., Myxilla (Ectyomyxilla) beauchênensis sp. nov., Tedania (Tedania) livida sp. nov., Amphilectus fimbriatus sp. nov. and Isodictya cutisanserina sp nov. Additional information is provided on several species recently described from the Falkland Islands and Amphimedon marsei is newly reported. The biogeography of the sponge fauna of the southern Falkland Islands is discussed.
