This plant is an excellent match to the photo of Ctsm. ivaneae in the article by Fred Clarke in the 2020 Supplement to the AOS "Orchids" magazine. The same photo appears in the OW and some photos in orchidroots.com are similar. The species is very distinctive in the genus and is endemic to Brazil (Amazonas, Rondonia). It was very recently described in 2016 in Orquidario Vol. 30.
