Abstract
Lateral horns on valves are found in few representatives from different families of the Anomopoda (Crustacea: Cladocera). We found that populations of "horned" Pleuroxus Baird, 1843 from mountains of Central Asia belong to two different species, P. pamirensis (Werestschagin, 1923) present in Pamirs, and P. annandalei (Daday, 1908), occuring in Tibetan Plateau, Baikal Rift System and Mongolian Altai. Redescriptions and a list of differences between the species are presented. Genera Cornuella Werestschagin, 1923 and Sinopleuroxus Chiang Sieh-chih, 1963 are suggested junior synonyms of Pleuroxus.References
