Stelis-acaroi-Timothy-Henry-CBR/AOS-2021-07-14 SITF determined this plant to be Stelis benzingii, not Stelis acaroi (Jan 2023); the plant did not match the description and drawings of S. acaroi; Alex Hirtz, co-author of Stelis acaroi stated the symmetry of the sepals, shape of the lip, petals, and column and central white line in the lip are diagnostic and the awarded plant is not S. acaroi; Rodolfo Solano-Gomez, Instituto Politecnico Nacional: Mexico, is a taxonomist familiar with Stelis responded to our request and found differences between our plant and the description, drawing and available photos of S. acaroi and identified Stelis benzingii, Luer & Hirtz, a species endemic to Ecuador, as the correct species.
