Pleurothallis carpishensis is described, illustrated, and compared to P. radula, from which it is differentiated by the flowers borne from a depressed spathaceous bract resting on a navicular concavity on the leaf, the oblong-lanceolate, apiculate petals, with large papillae on the margins, the triangular, subacute lip, with a basal, widely ovate and emarginate, papillose-verrucose callus, with two oblique, lateral and marginal keels.
