  Type: Odontosoria uncinella (Kunze) Fée [=Davallia uncinella Kunze]. Odontosoria is a genus of about ten species in the American tropics, with only one in Oaxaca. There are two species in Africa (Kramer, 1972), but most (six) of the species occur in the West Indies. It is probably most closely related to Sphenomeris. The genus is distinct by the sori in small pockets at segment apices and the rhizome indument of scales. References: Kramer, K. U. 1972. The lindsaeoid ferns of the Old World—IX.
