First record and new combination of a rissoid gastropod from off south Brazil

Fabio Wiggers, Inga Veitenheimer-Mendes

Resumo


After 35 years of its original description, Rissoa cruzi Castellanos & Fernández, 1974 is first recorded in southern Brazilian waters. An analysis of both shell and radular characteristics indicated that R. cruzi does not conform to its current generic assignment. Based on shell characters, R. cruzi is placed in the genus Alvania Risso, 1826. A comparison with other rissoids from the same region is also provided.
