Résumé

Synopsis: Fish distribution in a river within the drainage system of Zaire headwaters and with an unusual gradient was studied. The Luongo River has high gradient upper and lower sections, separated by a long middle section of no gradients, and bordered by rapids and waterfalls. On the basis of Luongo's hydrographic history, topography and fish taxocenes the river is divided into saltatory zones, each zone inhabited by separate homeostatic fish communities. The problem of river natural zonation is argued. Luongo River is, furthermore, unique for its high richness (49 species), biogeographical correlations, and the number of undescribed species found (14%), of which one,Chetia mola, is described in this study. The probable reasons for the richness and for the discontinuous fish assemblages are discussed.
