I've not personally seen Philine trapezia here in the waters of Okinawa's main island and Atsushi Ono mentions (pers. comm.) seeing only the above single featured animal in the Keramas*. Atsushi found this solitary animal amid an old fishing net which had been lost on a coral reef. Atsushi of course considers the species to be very rare in the Keramas.
