A new species of terrestrial Puya, from the coast of southern Peru is described. Hitherto the only known Puya from coastal Peru is Puya ferruginea (Ruiz & Pav.) L.B.Sm. which can be found growing on Cerro Campana near Trujillo. Herein reported Puya hoxeyi is found over 1200 km to the south growing on steep barren slopes in two small populations north of the town of Ilo in the department of Moquegua. A description and illustrations are provided together with a comparison with the likely close phylogenetically relative species from the “yellow flowered chilensis” group, namely the Chilean species Puya boliviensis Baker and Puya chilensis Molina.
