Abstract
A new species of Masdevallia genus is described here. Masdevallia purocafeana is immediately recognized by having conspicuously broad, echinate, and strongly reflexed lateral sepals. It is compared to Masdevallia alexandri but differs by having an oblong, shallowly concave, yellow-green dorsal sepal variegated with purple towards the apex, oblong petals light pink suffused with yellow and spotted with purple, and ovoid-ovate, reflexed light pink lip, dotted with pale light red.

Masdevallia purocafeana M. F. Monteros & Baquero, sp. nov.
Masdevallia purocafeana is similar to Masdevallia alexandri Luer (1980: 347) from which it differs by the ovate dorsal sepal with a reflexed tail at the apex (vs. suborbicular dorsal sepal, with an erect tail at the apex), the echinate, widely obovate lateral sepals 5–6 mm wide (vs. glabrous, obovate-oblong, 3 mm wide sepals), the oblong, not angular, petals with the apex irregularly truncate and unequal (vs. spatulate, multangular petals with an obtuse shortly apiculate apex) and the ovoid-ovate lip with three longitudinal calli on the disc (vs. oblong-subpandurate lip, the disc with a low pair of calli).
Etymology:—This species is named in honor of Puro Coffee, an organic coffee company in the United Kingdom that has made significant donations to the UK-based World Land Trust, which has financed land purchases for Fundación EcoMinga’s Manduriacu reserve where this species was discovered. Puro Coffee has played a major role in facilitating support for this reserve, thereby protecting many locally endemic species of plants and animals.

Resumen: Se describe una nueva especie del género Masdevallia. Masdevallia purocafeana se reconoce inmediatamente por tener sépalos laterales conspicuamente anchos, equinados y fuertemente reflexos. Se compara con Masdevallia alexandri, pero se diferencia por tener un sépalo dorsal oblongo, ligeramente cóncavo, de color amarillo verdoso variegado con púrpura hacia el ápice, pétalos oblongos de color rosa claro teñidos de amarillo, punteados de púrpura, y un labelo ovoide-ovado, reflexo de color rosa claro, punteado con rojo claro pálido.
