Hirtella barrosoi is slightly similar to H. parviunguis because of the elliptic glabrous leaves, with similar size and number of primary veins. However, H. barrosoi can be distinguished by the longer acumen ( 4–7 mm long vs. 3–4 mm long in H. parviunguis ), paniculate inflorescence with smaller bracts (1–1.2 vs. 6–7 mm long) and lower number of stamens (3 vs. 5). Collected with flowers in May.

Hirtella barrosoi is endemic to the Atlantic Forest, recorded only in Ombrophilous Forests in the states of Rio de Janeiro and EspÍrito Santo ( Barros et al. 2022). In EspÍrito Santo it occurs only in Santa Leopoldina municipality and is not recorded in any protected areas. This species was assessed as Data Deficient (DD) at a national level ( Fernandez 2018).
