Pupulin, F. 2007. A new species of Stenia (Orchidaceae: Zygopetalinae) from Ecuador, with a note on Stenia stenioides. Harvard Papers in Botany 12(1):7–13. 

Abstract
A new species of Steniafrom Ecuador, S. dodsoniana, is described and illustrated. Stenia dodsoniana is similar to S. stenioides, from which it mainly differs by the obscurely tri-lobed lip with the lateral lobes broadly truncate, the apical retrorse calli, the subventral anther and the almost absent lateral teeth of the rostellum. The identity of S. stenioides is discussed and the species is illustrated on the basis of an Ecuadorian specimen. The pollinarium morphology of Stenia is discussed.

Keywords
