| Abstract |
Four species of the genus Cunina, C. duplicata, C. peregrina, C. globosa and C. octonaria, have been reported from Japanese waters. However, some of species still unidentified. In this study, six specimens of an unidentified Cunina species collected from Kochi, Nagasaki and Okinawa prefectures were examined by morphological observations. The present study reports detailed observations of the morphology of one species newly recorded in Japan: Cunina simplex. This species possesses the following unique morphological characters: four manubrial pouches and four primary tentacles. This study reported C. simplex as the fifth described species from Japan. |
