Abstract :The genus Sauvetrea Szlach. (Orchidaceae) was segregated from Maxillaria sensu lato in 2007. It embraces a group of from 10 to nearly 20 species, all initially defined as Maxillaria sect. Trigonae. Sauvetrea can be easily distinguished from closely related Rhetinantha M.A.Blanco by the lip callus. During the revision of the materials stored in AMES we came across specimens collected by Vargas in Peru, which were initially identified by Schweinfurth as Maxillaria brachypetala Schltr. We compared Vargas's discovery with the protologue of the latter species and other Sauvetrea, but it does not fit the description of any genus representatives known so far. We describe it below as a new species,Sauvetrea schweinfurthiana Szlach. & Lipińska.
