This is one of several Marshall Islands crabs that have been identified on iNaturalist as Trapezia bidentata (here, here and here). Based on various traits such as the color of the body, eyes and chelipeds, I have a hard time accepting that they are all the same. For now, the IDs will be left tentative. The one on this page lives among the branches of living Pocillopora coral.
