New records of seven Solariellidae species (Ilanga, Phragmomphalina, Spectamen, Arxellia) from the north-western Madagascar area and the Mozambique Channel are listed, extending in some cases their distribution. A synthetic diagnosis is given for each species. Four new species are described and compared with similar species: Ilanga mese n. sp. from Mayotte, Bathymophila stephanephoros n. sp. and Minolia stronyle n. sp. from the Glorieuses Islands and Zetela williamsae n. sp. from the Mozambique Channel. |
