This species belongs to M. sect. Mormodes and is similar to M. vinacea and M. paraënsis but differs by the lip lanceolate-trullate with basal lateral lobes, which are rounded and inconspicuously obtuse. We provided description, taxonomic and ecological comments, state of conservation, geographic distribution map, illustrations of the new species.

Maxillaria luizotavioi (Orchidaceae: Maxillariinae): a new species from the Oriental Brazilian Amazon

“…The Orchidaceae is one of the ten richest families in the country, with about 2700 species, of which ca 30% occur in the Brazilian Amazon (BFG 2015, 2018, 2021, Flora e Funga do Brasil 2022). This number continuously increases with new records and descriptions of new species (Cantuária et al 2019, Engels et al 2019, 2020, Ferreira Filho and Barberena 2020, Hagsater and Krahl 2020, Engels and Smidt 2021, Pessoa and Karremans 2022).…”
