Abstract
Malaxis susanae from the Colombian Andes is described and illustrated as a new species of orchid. It resembles Malaxis carpinterae (Schltr.) Ames, but differs by the flowers that have a white (vs. green) lip and the disc cavity with the margin inconspicuously raised (vs. conspicuously raised in a retuse margin) at the apex. Notes on its distribution, habitat, floral phenology, etymology, related taxa, and conservation assessment are provided.

Malaxis susanae de los Andes colombianos es descrita e ilustrada como una nueva especie de orquídea. Se asemeja a Malaxis carpinterae (Schltr.) Ames, pero se diferencia por tener flores con el labio blanco (en comparación con verde) y la cavidad del disco con el margen discretamente elevado (en comparación conspicuamente elevado en un margen retuso) en el ápice. Se proporcionan notas sobre su distribución, hábitat, fenología floral, etimología, taxones relacionados y evaluación de conservación.
