Additional data are presented and discussed with regard to the taxonomy of the Brazilian species of Adenophaedra and Tetrorchidium . Both genera are poorly known and badly studied in Amazonia. Adenophaedra is represented in Brazil by three species: A. grandifolia, A.megalophylla and A. cearensis, the latter is proposed here as a new species. Tetrorchidium is represented by T. rubrivenium, T. parvulum, T. macrophyllum and T. duckei. Illustrations and keys to identify the genera and species, as well a map, are given as a contribution to a taxonomic review of these taxa.
