A new moss species, Didymodon lainzii J. A. Jiménez & M. J. Cano, is described and illustrated from south-western Ecuador and north-western Peru. It is characterized mainly by its linear-lanceolate to oblong-triangular and incurved leaves when dry, plane and bistratose margins above midleaf, the yellowish color in KOH, a hyaline area of rectangular cells on ventral surface of the costa, transverse section of the costa with 2–4 layers of guide cells and without ventral stereids. Its distinction from, and relationships with, some closely related species within the genus are discussed.
