Decapoda - Brachyura - Leucosiidae - Tanaoa

Tanaoa serenei (Richer de Forges, 1983)



Distribution : Galil (2007) : Marquesas Is., Tuamotu Archipelago, Society Is., Samoa, Banc Tuscarora, Wallis Is., New Zealand, Guam, 27-805 m (Galil 2003a), new record for the Solomons.

Remarks : In Hawaii T. serenei is 'replaced' by T. distinctus (Ratbhun, 1893) - see Ng & Richer de Forges, 2007. The two species are close. Specimens from the Marquesas could perhaps belong to T. distinctus, as several species from Hawaii have been found recently also in the Marquesas. However a specimen from the Marquesas (Marara, stn 299, trap 350 m, carapace length 30 mm, see photo) has clearly the large granules characteristic of T. serenei (much lower in T. distinctus).
