Comments: Removed from genus Trionyx and placed in genus Pelodiscus by Meylan (1987). Retained in genus Trionyx by Webb (1990). Specimens from Hawaii have been confused with Palea (Trionyx) STEINDACHNERI, which apparently also occurs there (see Webb 1980, McKeown 1978). An earlier specific name, ROSTRATA Thunberg, 1787, has been suppressed by the ICZN (see 1991 Bull. Zool. Nomen. 48(3):276).
