Finding
SITF confirms this plant as Zootrophion gracilentum (Feb 2025). It is a good match to Z. gracilentum, including the smaller leaf/plant proportion to the flowers, and the purple/burgundy underside of the leaves. This plant is a good match to Pupulin's photo in the October 2014 "Orchids" magazine. Key characteristics of Z. gracilentum are the dorsal sepal, which is more pointed, instead of hooking over and down in the closely related Z. hypodiscus and the smaller opening of the slot, which better fits Z. gracilentum than Z. hypodiscus, which has a larger opening.
