Identification. Formerly known as Ctenitis pedicellata (Christ) Copel. , which is now a synonym (Viveros et al. 2018). It is characterized by erect stems with dark brown to blackish scales, 1-pinnate-pinnatifid leaves, and the pinnae incised ca 1/2–2/3 the distance between segment apices and costae. Sori round, lacking indusia. Ctenitis submarginalis (Langsd. & Fisch.) Ching is the only other species of the genus in the area, differing by orangish stem scales and pinnae incised more than 3/4 the distance between segment apices and costae.

Distribution and habitat. Bolivia and Brazil. Terrestrial in forests.
