    A new species of Pleurothallis from subsection Macrophyllae-Racemosae is described from Valle del Cauca, Colombia. Morphological characteristics to distinguish this species from Pleurothallis bicornis, P. subreniformis and P. torrana are presented. The micromorphology of the lip of the new species was studied utilizing scanning electron microscopy. Labellar micromorphology is discussed in relation to putative pollination mechanisms.

The new species are distinguished based on their morphological distinctness from similar species. Pleurothallis kaynagata represents a new addition to Pleurothallis sect. Abortivae, which was previously thought to be monotypic. Acronia rinkei is transferred to Pleurothallis and provided with a new name, Pleurothallis neorinkei, and locality data.
