"Similar to S hylophila a higher elevation orchid, from which it differs in only trivial features, except for the markedly different lip which is type A, subquadrate, not longer than wide, witha thick, conspicuous, bilobed bar that is glabrous dorsally. S hylophila has a lip that is longer than wide with a simply curved bar and is minutely pubescent on the dorsum." Luer & Vasquez 2018
