A new species, Bocoa marionii, from the Upper Essequibo region, Guyana, is described and illustrated and its relationships with allied species are discussed. It is morphologically similar to B. prouacensis, from which it differs in its chartaceous leaflets, shorter inflorescences borne among leaves, longer pedicels, calyx that is strigose along the middle of the segments internally, and ovary densely yellow-sericeous. A key to the species of Bocoa is provided.
