A new species of Ficus L. sect. Americanae Miq. is described and illustrated in this paper as Ficus nigrotuberculata . It is characterized mainly by the surface of the syconium, which is covered with small black protuberances, and ostiole tubiform, and shows morphological similarities with F. pertusa L.f., F. trachelosyce Dugand and F. tubulosa Pelissari & Romaniuc. A key of these related species is also presented.
