Before this work, only Ochrotrichia patulosa ( Wasmund & Holzenthal 2007) — previously described in Rhyacopsyche Müller 1879 and transferred to Ochrotrichia by Oláh & Johanson (2011) — was known from Rio de Janeiro state. In addition to the three new species described here, we also record for the first time O. caatinga for Rio de Janeiro state. This species was previously described from Parque Nacional Ubajara, Ceará state, northeastern Brazil. Although located in the semiarid Caatinga biome, the protected area of Parque Nacional Ubajara is one of the last remnants of native Atlantic rainforest in northeastern Brazil, with vegetation structure similar to that of Parque Nacional da Tijuca, in Rio de Janeiro state, southeastern Brazil, where the species was also collected.

This species can be distinguished by the shape of the inferior appendages, subrectangular and rounded apically in lateral view, by the absence of a hook-like process on tergum X, and by the phallus with small spines on the apical area and bearing a curved lateral process (see figures 1A–1D in Souza et al. 2014).
