Thanks Ioarie. That are some very useful diagnostic keys!
Could you please verify whether the crab in this link is really an Arachnothelphusa sp.? http://www.lars-fehlandt.de/2018/02/05/a...
It is also an arboreal crab found in the same forest.

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. Compare https://www.inaturalist.org/taxa/85783-G...

Either that or Arachnothelphusa sp. which is also found in that area
