" Recent collecting in the Malawi lakes Chilwa and Chiuta has revealed a new haplochromine cichlid fish, Astatotilapia tweddlei, which is described and illustrated. It is distinguished from most members of this genus by an elongate, rounded caudal fin. Although having a distinctly different colour pattern and more slender pharyngeal bone, it shows a greater similarity to A. paludinosa, known only from the Malagarasi Swamp 1200 km to the north in the Zaire ichthyofaunal province, than it does to members of this genus from the closely adjacent Zambezi province from which this wetland system, in the East Coast province is separated by only some 50 km "
