Uca
Looks like Uca thayeri. The major claw is smaller proportionally to the carapace in this species

Uca thayeri?
Try Uca thayeri - Atlantic Mangrove Fiddler Crab. See range maps of Uca here. There's not much to choose from that look close.

U. pugilator??
After reading info under Potentially Misidentified Species here it seems like this may be U. pugilator.
