摘要：

Three new species of Magelona are described from the Seychelles: M. conversa, M. falcifera and M. gemmata. Magelona conversa belongs to a 'M. mirabilisgroup', having a rounded prostomium and specialised chaetae on chaetiger 9, but differs from all other members in having long prechaetal neuropodial lamellae on chaetigers 1–8. Magelona falcifera bears large sickle-shaped hooded hooks in the abdomen and thus approaches the genus Meredithia, but lacks prostomial horns. Magelona gemmata belongs to a 'M. longicornis group' in having distinct prostomial frontal horns, and a thorax with lanceolate postchaetal lamellae in the notopodia and ventral neuropodial lobes. The distinctively swollen bud-like tips on the notopodial lamellae of chaetiger 9 are an unique feature. The status of MeredithiaHernández-Alcántara & Solís-Weiss, 2000 and current magelonid terminology are discussed.
