Summary: | The morphology and distribution of Catenula adhaerens Mereschkowsky was studied from 24 beaches in southern Brazil. The study was based on observation of 214 samples from superfi cial sediments of sandy beaches from the states of Rio Grande do Sul and Santa Catarina. The morphological variability observed in Brazilian specimens was similar to those described in literature, except for the stauro that was absent in some valves. Catenula adhaerens presented a wide distribution, occurring in exposed, dissipative and refl ective sandy beaches. However, it occurred with most relative frequency (22%) in estuarine beaches. The species was not observed in the open, exposed and dissipative sandy beaches. This absence might be related to the beach hydrodynamic, sand grain size, shape and superfi cial texture limiting the Catenula adhaerens distribution in southern Brazil. |

O estudo foi baseado na observação de 214 amostras coletadas em sedimentos superfi ciais de praias arenosas dos estados do Rio Grande do Sul e Santa Catarina. A variabilidade morfológica observada nos espécimes brasileiros foi semelhanteà descrita na literatura, exceto em relação à presença de estauro que se fez ausente em alguns indivíduos. Catenula adhaerens apresentou ampla distribuição, ocorrendo em praias arenosas marinhas expostas, dissipativas, refl ectivas e baías. Entretanto, ocorreu com maior abundância relativa (22%) em praias estuarinas. A espécie não foi observada em praias oceânicas abertas, expostas e dissipativas, fato que sugere que a hidrodinâmica da praia, associada ao tamanho, forma e textura superfi cial dos grãos de areia, pode ser um fator limitante na ocorrência de Catenula adhaerens no sul do Brasil.Iheringia.
