Freshwater crabs (Brachyura: Potamoidea: Potamonauticlae) from the rainforests of the Central African Republic, Central Africa

摘要

A collection of freshwater crabs of the family Potamonautidae from the Central African Republic made recently by the Central African Republic Expedition of the American Museum of Natural History, New York, comprised four species in two genera. The collection included two species of Potamonautes MacLeay, 1838, P. paecilei A. Milne-Edwards, 1886, and P. ballayi A. Milne-Edwards, 1886 and two species of Sudanonautes Bott, 1955, S. africanus A. Milne-Edwards, 1869, and S. sangha, new species. Only six species of freshwater crabs have been previously reported to occur in the Central African Republic. The addition of S. africanus and S. sangha brings to eight the number of species of freshwater crabs reported from that country.
