In this study, we list 25 moss species belonging to Sematophyllaceae s. str. Six species are reported for the first time from some of the states in the Northeast Region of Brazil. Sematophyllum succedaneum (Hook.f. & Wilson) Mitt. stands out for being found for the first time in this region. The Atlantic Forest is the phytogeographic domain with the greatest number of Sematophyllaceae species, which are either exclusive to this domain or shared with the Caatinga and/or Cerrado. Our study expands on the previous knowledge of these species and provides a foundation for further studies.
Durante a revisão de espécies da família Sematophyllaceae depositadas em herbários nacionais foi possível ampliar o registro de ocorrência de Meiothecium boryanum (Müll.Hal.) Mitt. no Brasil. Atualmente a ocorrência confirmada da espécie se limita aos Estados da Bahia, Goiás, Rio de Janeiro, Rio Grande do Sul e São Paulo, embora seja citada apenas o Estado da Bahia no Flora e Funga do Brasil 2022. Com este trabalho, a espécie teve seu registro confirmado também para os estados de Minas Gerais e Pernambuco.
