Deiregyne callifera Salazar & Hernández-Cardona, a new orchid species from the foothills of the Sierra Madre Oriental in the state of Hidalgo, Mexico is described and illustrated. The new species is similar to sympatric D. eriophora (B.L.Rob. & Greenm.) Garay, differing in the glabrous inflorescence with more numerous, smaller flowers arranged in several intertwined spirals, proximal part of the labellum wider than long and provided with a lunate, prominently papillose callus, and proportionately much shorter column with inflexed apex.
