During the taxonomic revision of the Neotropical Bulbophyllum (Orchidaceae) species, a new species was discovered from Bom Sucesso, Minas Gerais State, described and illustrated here as B. hatschbachianum E. C. Smidt & Borba. This species belongs to the Neotropical section Xiphizusa (Rchb. f.) Cogn. and posses a lip epichile completely different from the related species. It is closely to B. plumosum (Barb. Rodr.) Cogn. due to its vegetative morphology, but has different flower size, color and lip epichile. In B. plumosum the epichile is thin, longer and wider than the hipochile. In B. hatschbachianum the epichile is fleshy, shortest than the hipochile, thin, and sharply narrower than the hipochile. The flowers of this new species is similar to the Mexican B. solteroi R. González, but the general morphology of the lip, trichome size and the geographical distribution clearly distinguishes apart the two species.
