N. Cumberlidge, REMARKS ON THE TAXONOMY OF SUDANONAUTES CHAVANESII (MILNEEDWARDS,A., 1886) (BRACHYURA, POTAMOIDEA, POTAMONAUTIDAE) FROM CENTRAL-AFRICA, Proceedings of the Biological Society of Washington, 108(2), 1995, pp. 238-246
The fresh-water crab Sudanonautes chavanesii (A. Milne-Edwards, 1886)
is redescribed from new material which is compared to previous descrip
tions of the male type from Gabon. The gonopods and mandibles of a mal
e from Cameroon are described and illustrated for the first time. New
records of specimens from several museum collections are presented. Th
e species is recognized by a combination of characters of the carapace
, chelipeds, mandibles, and gonopod 1. The range of S. chavanesii has
been found to be restricted to an area from south Cameroon to Gabon; t
he species does not occur in West Africa (from Senegal to Nigeria), as
previously thought.
