The new species Ormosia corcovada (Fabaceae, Papilionoideae, Ormosieae) from the lower Cauca River basin in NW Colombia is described and illustrated, and its taxonomic affinities are discussed.

Both species belong to Ormosia section Unicolores but are geographically and morphologically distinct, especially with respect to leaflet shape and number of secondary veins.
