Abstract During a 1987–88 extensive limnological study of Spanish reservoirs, euplanktonic cladocerans were sampled all around the country. Two species of Diaphanosoma Fischer, 1850 were recorded, viz D. mongolianum Uéno, 1938 and D. brachyurum (Liévin, 1848). Morphological descriptions of both species are presented, especially of the thoracic limbs, together with notes on their ecology. Both species present a clear allopatric distribution, D. brachyurum inhabiting waters with a low Total Dissolved Salt (TDS) content, which equilibrated relative ionic composition, characteristic of a narrow strip in the northern part of the Iberian Peninsula; on the contrary, D. mongolianum inhabits waters with high TDS values and high content of sulphate or chloride, characteristic of the central and southern regions.
