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&#8217; to 7º56&#8217; S. The new species closely resembles C. septentrionalis, with which it grows partly 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.]]></p></abstract>

Sin embargo, recientes exploraciones de campo y la revisión de ejemplares de herbario han permitido descubrir una nueva especie del norte del Perú. Aquí describimos e ilustramos a Chloraea aequatorialis, la especie con la distribución más al norte registrada para el género, entre los 5º50&#8217; y 7º56&#8217; S. La nueva especie es más similar a C. septentrionalis, con la que crece parcialmente en simpatría en los departamentos de Cajamarca y La Libertad, pero se diferencia fácilmente de esta por tener sépalos y pétalos más grandes, disco del labelo cubierto por apéndices largos, delgados y angostos, la uña del labelo, columna y antera más largas, y el estigma más corto. Proporcionamos información sobre el hábitat, distribución y estado de conservación de la nueva especie, una descripción actualizada de C. septentrionalis y una clave para las especies peruanas de Chloraea.]]></p></abstract>
