Trichodactylidae is a family of crabs, in its own superfamily, Trichodactyloidea. They are all freshwater animals from Central and South America,[2] including some offshore islands, such as Ilhabela, São Paulo.[3] Only one of the 50 species is known from the fossil record, Sylviocarcinus piriformis from the Miocene of Colombia.[4] The family contains 15 genera in two subfamilies:[5]
