In Peru, Chloraea previously included five species. However, recent field explorations and herbarium specimen revisions have led to the discovery of a new species from northern Peru. Here, we describe and illustrate Chloraea aequatorialis, the species with the most northern distribution recorded for the genus, ranging from 5º50’ to 7º56’ S. The new species closely resembles C. septentrionalis, with which it grows partially in sympatry in the departments of Cajamarca and La Libertad, but it can be easily distinguished by its larger sepals and petals, a lip disc covered by thin, narrow, and long appendages, a longer lip claw, column, and anther, and a shorter stigma. We provide information on the habitat, distribution, and conservation status of the new species, along with an updated description of C. septentrionalis and a key to the Peruvian species of Chloraea.
