SITF has determined this plant to be Acianthera lepidota, not Acianthera cachensis (Nov 2023). Identification was made with the assistance of Dr. Adam Karremans, the taxonomist of record for A. cachensis and a noted authority on Costa Rican Pleurothallids. Acianthera lepidota is from Costa Rica and Panama and is closely related to A. cachensis. Descriptions of these two species with photos are in Adam Karremans 2020 book "Pleurothallids Neotropical Jewels, Vol. 1". The purple veined leaves of A. lepidota and the flower form is a better match to this plant than is A. cachensis. A drawing and photo can also be found in the IOSPE, as Pleurothallis lepidota (a synonym).
