Preparation of a treatment of the Annonaceae for the Flora Mesoamericana necessitates the description of five new species of Stenanona (S. carrillensis, S. hondurensis, S. monticola, S. tuberculata and S. tubiflora); three additional new species are described from Colombia (S. columbiensis and S. narinensis) and Mexico (S. wendtii). A key to the 14 recognized species in the genus is presented, as well as notes on potential relationships, distribution, and conservation status.
