Found in Puno department of Peru at elevations around 2000 meters as a miniature sized, cool to cold growing, caespitose epiphyte with slender, erect, terete ramicauls enveloped by a tubular sheath above and another at the base carrying an erect, coriaceous, elliptical-obovate, subacute, gradually narrowing below into the long-petiolate base leaf that that blooms in the later spring on a slender, erect to suberect, peduncle 2" [5 cm] long, single flowered inflorescence with shorter than the pedicels floral bracts and carrying flowers with snow white sepals with a dark spot on either side above the base, white petals and a white lip

"Among the species of SUBGENUS Masdevallia SECTION Masdevallia SUBSECTION Masdevallia, this species from southernmost Peru is most closely allied to Masdevallia chuspipatae Luer & Teague from central Bolivia. M deburgraevei differs from the latter by a shorter and proportionately wider sepaline tube with shorter tails. The tube is snow white with a small, dark spot above the base, instead of white suffused with orange below the middle. The petals are distinctly unguiculate with long processes above the claw that curve to meet below the column. The lips of these two species are superficially similar." Luer 2012
