ABSTRACT. The South-American cladoceran Alona muelleri Richard, 1897, (original spelling A. mulleri) is redescribed and translocated to the genus Karualona Dumont & Silva-Briano, 2000. K. muelleri was presumed to be a synonym of Karualona karua (King, 1843), but differs from other species of Karualona by morphology of postabdomen and postabdominal claws, shape of exopodites III–IV, armament of IDL and ODL. The closest relative of K. muelleri is the Mexican K. pennuelasi Dumont & Silva-Briano, 2000. Relationships of K. muelleri within the genus, its ecology and distribution are discussed. An updated key to species of Karualona of the world is provided.
