Abstract

The neotropical genus Dussia (Fabaceae, Papilionoideae) comprises 11 species distributed from Mexico to the Brazilian Amazon. During fieldwork, we collected a morphologically distinct specimen exhibiting characteristics not found in any known species, suggesting a taxonomic novelty. Subsequent herbaria revision and morphological analysis confirmed it as a new species, here named Dussia filibracteolata. The new species is endemic to the Andean forest slopes in Colombia and is distinguished by its filiform bracteoles, subequal calyx lobes, a light pink standard with yellow nectar guides, and dark pink wings and keel petals. We provide illustrations, a distribution map, taxonomic comparisons, and an identification key for the Dussia species of northern South America.
