Abstract
Two new Mesoamerican species of the papilionoid legume genus Harpalyce are described and illustrated. Harpalyce torresii São-Mateus & M. Sousa occurs in Belize and Mexico, whereas Harpalyce yucatanense Miranda ex São-Mateus & M. Sousa seems to be narrowly endemic to the Yucatan Peninsula. The discovery of these two new species highlights the diversity of Harpalyce in Mesoamerica.
