Abstract

There are 52 species of freshwater crabs in Sri Lanka and 51 of them are endemic. There are several species that are known only from a single locality.  Ceylonthelphusa armata is such a species, and we have initiated a study to record the distribution of this species as its typical locality is heavily polluted at Kadugannawa.  At present C. armata is known from six localities, and this information will be useful to facilitate the conservation of the species by assessing the Red List.
