Distribution and bathymetric range: This species was previously described with type-material from the coast of Buenos Aires, Argentina,at depths between 14 and 21 meters. Later, the species was found on samples off the coast of the Brazilian states of Rio de Janeiro, SÃo Paulo and Santa Catarina ranging from 28 to 72 m depth. Here we report it for the continental slope of the state of Rio Grande do Norte at depths ranging from 135 to 173 meters.

Remarks: This species was recently redescribed with material from the coasts of the Brazilian states of Rio de Janeiro, SÃo Paulo and Santa Catarina. The individuals found here agree with its original description although expected differences are observed such as setation due to maturity stages.This is the deepest and northernmost record of the species and its first record to northeastern Brazil.
