"Acianthera calopedilon is common in private collections and usually confused with P saundersiana, from which it is distinguished by the distinct convex, broadly obtuse lip. It is similar to P. cephalopodiglossa, with which it has been also confused, but differs mainly in the shape of lateral sepals and lip." Luer & Toscano 2015
