Abstract

ABSTRACTRecent taxonomic studies of forest habitats in South Africa have revealed the presence of three new species of freshwater crabs, suggesting that decapod diversity within the indigenous forest biome remain poorly documented. Surveys of the freshwater crabs of north eastern KwaZulu-Natal province produced a number of specimens from Ntendeka Wilderness Area (Ngome forest) and Nkandla and Ngoye forests that proved to belong to two new species following morphological and molecular analysis (mtDNA sequencing of three loci, 12S rRNA, 16S rRNA and COI). Two undescribed species, P. ntendekaensis sp. nov. and P. ngoyensis sp. nov. are described. The divergence time estimation of the new phylogeny for eastern and southern African freshwater crabs is discussed to illuminate biogeographic patterning and to understand factors responsible for cladogenesis.
