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.
