This works presents the taxonomic treatment for the species of Terpsichore and Zygophlebia that occurs in Brazil. Terpsichore is represented by 12 species, mostly occuring in the southeastern and southern Brazilian Atlantic Rain Forest, and a few (four) that are endemic to the mountains by the boundary between Brazil, Venezuela and Guayana. The genus Zygophlebia, with only one species (Zygophlebia longipilosa (C.Chr.) L.E. Bishop) is endemic to the Atlantic Rain Forest of southeastern and southern Brazil. In this paper are included a critical analysis of each species and their synonymy, as well as geographical distribution, identification keys, comments about related species, and illustrations.
