Specimens of the cirriped, Megalasma minus Annandale, 1906, were collected at the Okinawa deep-sea water facility through the deep-water inlet placed off-Kume Island at a water depth of 612 m in the Eastern China Sea. This is the first collection of the cirriped species from the Eastern China Sea water. Based on morphological features, we propose a new Japanese scientific name, Yarino-ho-uni-eboshi, for the species.
