Popis:	Summary A new population of African reed warblers, Acrocephalus baeticatus hopsoni, is described from Lake Chad. Its characters, together with those of unallocated material from Senegal, Eritrea and Tibesti, are intermediate between the Palaearctic A. dumetorum and other races of A. baeticatus. It is concluded that dumetorum is conspecific with A. baeticatus, and by priority becomes A. baeticatus dumetorum. The merits of A. palustris, A. scirpaceus and Hippolais pallida for inclusion in an A. baeticatus superspecies are considered, but allow no firm conclusion.
