Dasltröm, S. & S. Ruiz Pérez. 2015. Two new similar species of Masdevallia (Orchidaceae: Pleurothallidinae) from Pasco, Peru. Lankesteriana 15(1): 59–65.

Abstract. Two new species of Masdevallia, subgenus Pygmaeia, section Amaluzae are described, illustrated with line drawings and color photographs, and compared with similar taxa. The two new species are sympatric and share many morphological characteristics, but differ from each other through features such as pubescent sepals versus glabrous sepals, size and coloration. Both new species differ from all other members of the same subgenus and section by much larger plant habits.

Key words: New Masdevallia, Pleurothallidinae, Epidendreae, Epidendroideae, Pasco, Peru, taxonomy
