Comment(s) on data
See Macpherson & Baba (2010: 421) - Not Sadayoshia aff. edwardsii Poupin, 1996b: 24, 25 (fig. g) (Tuamotu Archipelago, 140 m) (= S. latisternata n. sp.).
Remarque sur le spécimen de BIOLAVE (juv. Lc 2.5 mm) : en toute rigueur, la clé de Macpherson & Baba (2012: 31) amène à S. miyakei Baba qui n'a pas d'épine mésiale à l'épine antérolatérale de la carapace. En toute rigueur S. miyakei Baba n'est connu avec certitude que du Pacifique occidental Japon, Salomon, Nouvelle-Calédonie) et il semble préférable de conserver le spécimen de la Réunion sous S. edwardsii forme juvénile. Les deux espèces ont parfois été mises en synonymie. Un autre spécimen (n30) plus gros est bien conforme à Sadayoshia edwardsii.
