Along the Brazilian coast, three species of the genus <i>Nausithoe</i> Kölliker, 1853 have been recorded: <i>Nausithoe atlantica</i> Broch, 1914, <i>Nausithoe punctata</i> Kölliker, 1853, and <i>Nausithoe aurea</i> Silveira & Morandini, 1997. Living polyps (<i>n</i> = 9) of an unidentified nausithoid were collected in September 2002 off Arraial do Cabo (Rio de Janeiro, southeastern Brazil) at a depth of 227 m, and have been kept in culture since then. We compared these specimens with three species cultured in our laboratory: <i>Nausithoe aurea</i> (from Ilhabela, São Paulo, Brazil), <i>Nausithoe maculata</i> Jarms, 1990 (from Cuba and Puerto Rico), and <i>NausithoZooKeys1-21https://www.ebi.ac.uk/biostudies/studies/S-EPMC7658188biostudies-literatureNew record of <i>Nausithoe werneri</i> (Scyphozoa, Coronatae, Nausithoidae) from the Brazilian coast and a new synonymy for <i>Nausithoe maculata</i>.PMC7658188Morandini ACMolinari CGMaronna MMfalseNew record of <i>Nausithoe werneri</i> (Scyphozoa, Coronatae, Nausithoidae) from the Brazilian coast and a new synonymy for <i>Nausithoe maculata</i>.The order Coronatae (Scyphozoa) includes six families, of which Nausithoidae Haeckel, 1880 is the most diverse with 26 species.
