Remarks. Tanaoa serenei (Richer de Forges 1983) was described based on specimens from Tahiti (R/V Tainui, trap, 400–500 m), Samoa, and Guam (Richer de Forges 1983: 634). Galil (2003: 402) has synonymised T. serenei with T. distinctus (Rathbun, 1894) . Recently, however, Ng & Richer de Forges (2007: 16) concluded that the two species are distinct, with T. distinctus known with certainty only from the Hawaii Is. and T. serenei from French Polynesia, Wallis & Futuna, Samoa, Guam, and questionably from the Solomon Is. (as T. distinctus; in Galil 2007), and New Zealand (as T. distinctus; in Galil 2003 and Yaldwyn & Webber 2011).
