摘要

Two tropical fish species, Epiplatys bifasciatus and Hemichromis fasciatus, are recorded for the first time fromthe Sahara desert, in Lake Boukou and Lake Djara respectively, two of the seven Ounianga Serir lakes in northern Chad.The nearest known populations of these two species are located 900 km to the southwest in Lake Chad. The OuniangaSerir lakes, which resisted the increasing aridity of Sahara since the Holocene by virtue of subsurface inflow of freshgroundwater from a large fossil aquifer, present the richest relict fish fauna of the Sahara, with at least eight species, includingalso Hemichromis cf. letourneuxi, Sarotherodon galilaeus borkuanus, Coptodon zillii, Astatotilapia tchadensis,Polypterus senegalus and Poropanchax normani.
