SUMMARY:

The Hymenophyllaceae family is considered the most representative basal family within the leptosporangiate ferns group with 600 species distributed in nine genera (Abrodictyum C.Presl, Callistopteris Copel, Cephalomanes C.Presl, Crepidomanes C.Presl, Didymoglossum Desv., Hymenophyllum Sw., Polyphlebium Copel., Trichomanes L., and Vandenboschia Copel.), in tropical and humid temperate regions of the world. For Brazil, 82 species are registered, of which 28 are of the genus Hymenophyllum and 55 of Trichomanes. The family presents a great variation in the form of life, substrate and preferred environment. Regarding the region that is home to the state of Rondônia, floristic and taxonomic studies of the family are still incipient. Therefore, the present work was designed with the aim of expanding floristic knowledge of the taxon in Rondônia, highlighting the importance of ferns and lycophytes in the composition of the regional flora. Records of occurrence and taxonomic treatment of specimens were obtained through digital platforms (GBIF, Specieslink, Reflora and MG), and the Herbarium Rondoniense collection. The data obtained demonstrated the occurrence of five genera (Abrodictyum, Didymoglossum, Hymenophyllum, Trichomanes, and Vandenboschia) with a total of 23 species, of which two are presented as new records for the state of Rondônia, being Trichomanes macilentum Bosch. and T. accedens C.Presl.
