Gabadage’s Freshwater Crab was described in 2005 based on two male specimens that had been collected in 1996.

This is a very small species whose carapaces reach sizes of only about 1,2 by 0,9 cm; its coloration in life is not known.

Gabadage’s Freshwater Crab is known only from its type locality, a small stream along a footpath to the Samanalakanda (Adam’s Peak), central Sri Lanka, where the animals hid themselves in wet soil under stones; it was never found since the type collection, despite several field searches. [1]
