This name has been used multiple times. The first was by H. Milne Edwards (1837). Gelasimus platydactylus H. Milne Edwards, 1837, is a junior synonym of Uca major (Herbst, 1782).

It was later used by Monod (1927) as a variant of Uca tangeri; when he realized platydactylus was already occupied by the earlier use, he renamed his variant matandensis.
