Abstract

A new species of Matelea s.l. (Apocynaceae: Asclepiadoideae, Asclepiadeae, Gonolobinae) is described from coastal Colombia: Matelea dugandii. The species belongs to the Ibatia species complex in Matelea s.l., but exhibits distinct differences in floral characters from previously known taxa, particularly in the terminal style-head appendage. An updated key to members of the complex in northern South America and the West Indies is provided, including M. cumanensis, M. fontana, M. maritima, M. pacifica, and M. rubra.
