The genus Callistopteris was erected by Edwin Copeland in 1938. Its status, like other genera in the family Hymenophyllaceae, remains disputed. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus, placing it in the subfamily Trichomanoideae, and saying that there are five species. As of October 2019, the Checklist of Ferns and Lycophytes of the World lists six species, whereas Plants of the World Online sinks the genus into Trichomanes.

Species

As of October 2026, the Checklist of Ferns and Lycophytes of the World and World Flora Online recognize 5 species in Callistopteris. Plants of the World Online recognizes these 5 species in a broadly circumscribed Trichomanes.
