Abstract
We describe a new species and propose a new combination of Ctenitis from South America. The new species is from Peru. We named it Ctenitis megalastriformis due to the resemblance to Megalastrum. The new combination corresponds to the species known until now as C. pedicellata. This species should be called C. nervata, based on the older name Aspidium nervatum. Lectotypes are designated for A. pedicellatum and Dryopteris indecora, both considered here to be synonyms of C. nervata.
