Brachyuran research in Malaysia started late in 1930s but there were still very
limited data on the diversity, environment biology and ecology of many
terrestrial and freshwater crab species. Aims of this study are to determine the
diversity of freshwater crabs and to examine some aspect of the biology and
ecology of freshwater crabs in Terengganu. This study was conducted in three
sites at Terengganu which are Sekayu, Tasik Kenyir and Chemerong. Four
species, Gempala bilobata, Heterothelphusa insolita, Parathelphusa maculata
and Johora thoi of freshwater crab were identified from 231 individuals
collected. A new distribution record was found for Johora thoi which was
previously known only to Pulau Redang and Chemerong was the southernmost
distributional limit of this species. Nine species of freshwater and terrestrial
crabs known to Terengganu and three species are in endemic state. Additional
surveys may produce more species as many habitats are yet to be explored.
