ABSTRACT. Family Bosminidae Baird, 1845 sensu Sars, 1865 (Crustacea: Cladocera) is among the macrotaxa attracting attention of few recent taxonomists. The aim of this paper is to redescribe two endemic Neotropical species, B. negrensis Brandorff, 1976 and B. brandorffi Rey et Vásquez, 1989 in detail and to check the monophyly of the genus Bosminopsis Richard, 1895. Our study confirmed a remarkable similarity of the thoracic limbs in all known species from this genus, supporting the genus monophyly. At the same time, morphology of valves is different in different species of Bosminopsis, analogously to differences between taxa of the second bosminid genus, Bosmina Baird, 1845.

KEY WORDS: Anomopoda, Bosminidae, morphology, taxonomy, South America.
