[The snakes of Senegal: an annotated species list].

Between 1990 and 2001, the laboratory of Paludologie of IRD at Dakar collected over 5,500 snakes from all over Senegal. By studying this collection, an entirely new species was discovered for science and eight new species for Senegal. The presence of many specimens of rare species and the great number of localities from which snakes were collected also allowed us to solve several delicate taxonomic problems and better to specify the biogeography of Senegalese snakes. Currently, the presence in Senegal of at least 55 different species has been established with certainty. The data collected simultaneously on the burden of snakebites for public health shows considerable differences according to geographic area, with populations from south-eastern Senegal being more exposed to the risk of death by snakebite.
