Abstract
A new species of Ovalona Van Damme & Dumont, 2008 (Cladocera: Anomopoda) related to the rare Australian species Ovalona archeri (Sars, 1888), is described from the Mekong Delta, South Vietnam. Ovalona garibiani sp. nov. differs from O. archeri in morphology of antenna, postabdomen, and proportions of setae on thoracic limbs II–III. Both species differ from other species of the genus Ovalona in the postabdomen with a narrow and sparsely spaced group of lateral setulae, the distance between the postanal groups being slightly greater than the width of the group. O. garibiani sp. nov. is a rare phytophilous species, known from a few localities in continental Malaysia, Southern Thailand and Vietnam.
