ABSTRACT. A new species of cladoceran from the family Chydoridae (Branchiopoda, Anomopoda) from the Drakensberg Mountains of South Africa is described. Alona meridionalis sp.n. differs from the other species of Alona by transverse lateral head pores without pocket-like cavities under them. Morphology and position of the new species within the genus are discussed. It seems to be closely related to the pair of Iberian species inhabiting strongly mineralized waters, Alona salina Alonso, 1996 and Alona orellanai Alonso, 1996.
