I'm pretty certain this is Sesarmidae (https://www.inaturalist.org/taxa/84967-S...) of which Geosesarma is a member based on the square carapace, widely set eyes, and arboreal habits. Gecarcinucidae of which Arachnothelphusa is a member tend to have rounder carapaces with beady eyes in deeply set orbits, and also tend to be in mud/water, not in trees.
