Notes on wentletrap snail Alexania inazawai (Kuroda, 1943) from Xiamen, China, and its obligatory ectoparasitic behaviour on Orange-Striped Anemone Diadumene lineata (Verrill, 1869)
福建厦门潮间带的稻泽亚梯螺及其专性寄生纵条矶海葵的记述
Abstract
Alexania inazawai (Kuroda, 1943) is an ectoparasitic epitoniid obligatorily feeding on the sea anemone Diadumene lineata (Verrill, 1869). Alexania inazawai is originally described from Japan and had several records in China in recent years. In this work, Alexania inazawai populations discovered from three different sites in Xiamen are reported, and their habit and the evolutionary feature of this species is discussed.
Key words: China, Xiamen, malacofauna, obligatory parasite
