A new species of Opilionanthe (Pleurothallidinae, Orchidaceae) and new records in the Lepanthes clade for Perú

A new species of Opilionanthe , viz O. magdalenae , from the montane forest of Perú is described and illustrated. Opilionanthe magdalenae is the second species of the genus and is distinguished from its congener O. manningii by its narrow leaves (only 0.7 mm wide), reddish flowers with petals about half the length of the sepals, and a lip with rounded lateral lobes. Additionally, eleven new country records of species in the Lepanthes clade are presented based on field explorations and herbarium revision. Information about the habitat and distribution of all species treated are provided.
