Abstract

A new species of the genus Drymonia (Gesneriaceae) from the Serranía de los Paraguas in the Cordillera Occidental from the Colombian Andes, is here described. The new species, Drymonia paraguensis Clavijo & Zuluaga, is distinguished by a rugose and grooved stem with lenticels, decurrent winged petioles that often fuse with the opposite petiole forming a wing around the node, blades drying dark maroon with four main lateral veins, ovate calyx lobes covering two thirds of the corolla with long attenuate apex, and laciniate corolla lobe margins. The species is only known from three localities in the Serranía de los Paraguas, in the departments of Chocó and Valle del Cauca, a biodiversity hotspot in the tropical Andes that harbors high richness of Gesneriaceae. Detailed morphological comparisons with similar species, digital photographs, an illustration, and a preliminary IUCN risk assessment are provided for the new species.
