Dynomene tanensis - Poupin, 1996a: 97 (Checklist); 1996b: 26, pl. 12f (Fangataufa; 310 m; coll. Frv Marara, fr). - Metadynomene tanensis - McLay, 1999: 521 (Fangataufa; new combination). - Metadynomene aff. tanensis - McLay & Ng, 2005: 25 ("McLay (1999: 522) reported a large male specimen (29.1 x 27.6 mm) from Tuamotu,French Polynesia as being M. tanensis, but it now appears this specimen belongs to a new species. The anterolateral teeth are much smaller than in the present specimens and are arranged differently. We prefer to wait until more specimens, including females, become available before describing it as a new species. Thus the distribution of M. tanensis is now confined to the west Pacific. - Metadynome tuamotu Ng & McLay, 2010 - The Tuamotu specimen.
Comment(s) on data
McLay & Ng (2006: 25) - Metadynomene tanensis is a deep water dynomenid that has been found in the range 205-520 m. Its distribution includes Japan, Taiwan, Indonesia, Vanuatu, New Caledonia, Loyalty and Chesterfield Islands. Therefore the occurrence of M. tanensis in the Philippines is a new record, but it does not extend the geographic range of the species. The Tuamotu specimen in McLay (1999) belongs to a new species, for the time being M. aff. tanensis.
