Canavalia llanorum (subgenus Wenderothia) from the northwestern Llanos region of Colombia and Venezuela (Orinoquia) is described and illustrated, and its morphological relationship with an allied species is discussed. The new species is morphologically related to C. bicarinata, but it differs mainly by its legumes having only one extra medium rib (vs. two ribs in C. bicarinata), and by its leaflets elliptic-ovate or obovate (vs. ovate). We also discuss the phylogenetic position of C. llanorum and present geographical and ecological information about the new species.ResumenCanavalia llanorum (subgénero Wenderothia) de la región Noroeste de los Llanos de Colombia y Venezuela (Orinoquia), es descrita, ilustrada y sus relaciones morfológicas con su especie afín son discutidas. Esta nueva especie presenta similitudes con C. bicarinata, sin embargo, difiere por la legumbre con una sola costilla en el medio (vs. dos costillas en C. bicarinata) y por los folíolos elípticos-ovados hasta obovados (vs. ovados). Se discute la posición sistemática de C. llanorum basada en análisis filogenéticos, y se presenta información acerca de la distribución y ecología de la nueva especie.
