ABSTRACT Sixteen species of the microcaddisfly Ochrotrichia Mosely, 1934 (Hydroptilidae) have been recorded so far in Brazil, mainly distributed in the Atlantic Forest of southeastern Brazil. In order to reduce the Linnean and Wallacean shortfalls for the Ochrotrichia Brazilian fauna, we diagnose, describe, and illustrate three new species based on adult males from three protected and preserved areas of the Cerrado biome of Federal District (Central-West region), Minas Gerais (Southeast region) and Tocantins (North region) states; all of them named in honor of three great Brazilian entomologists viz., Ochrotrichia froehlichi sp. nov., Ochrotrichia machadoi sp. nov. and Ochrotrichia nessimiani sp. nov. They can be recognized mainly by the morphology of the tergum X, number, and position of the spine-like setae of the inferior appendages. This contribution represents the first record of Ochrotrichia for the Central-West region, increasing the number of species of this genus in Cerrado biome from one to four, and is the first report of a microcaddisfly for the Federal District. In addition, the genus is reported for the first time from Paraná, São Francisco, and Tocantins hydrographic basins. Finally, we provide a checklist of the Ochrotrichia species from Brazil.
