Pleurothallis puyoensis Criollo, sp. nov.
Diagnosis.— Pleurothallis puyoensis is similar to P. lilijae Foldats (1968), but the former new species differs from the later by petals sessile(vs. unguiculate), shorter ovary (2.3–3 mm vs. 5–8 mm long), smaller dorsal sepal (3.3–4 × 3–4.5 mm vs. 7–13 × 7–10 mm), smaller synsepal(4–4.2 × 2.5–3 mm vs. 8–12 × 3.5–5 mm), and lip adnate (vs. erect).
