E-mail: Abstract: Catenicella species described C.Although contei there are six species of Catenicellidae recordedC. in elegans Brazil, the three here are the first mention of the genus in the state of Rio de Janeiro, enlarging their distribution along the Brazilian coast. Previously, was recorded in Pernambuco and São Paulo, while was recorded in the states of Alagoas and São Paulo. The recent identification of these species in the state of Rio de Janeiro suggests two possibilities: it is difficult to find them due to small size and cryptic habitat, and/or they represent introduced species. The superfamily Catenicelloidea (Busk, 1852) ethanol and stored at the Bryozoa Collection of the Museu electron microscopy was made with specimens dried and includes five families (Petalostegidae, Concatenellidae, Nacional, Universidade Federal do Rio de Janeiro.
