Abstract

Three Aequorea macrodactyla (Brandt 1835) medusae were found along the So Paulo and Rio de Janeiro coasts. The specimens clearly match the diagnosis of the species, as they have tentacular bulbs with a large abaxial keel and a prominent excretory pore and papilla. The number of tentacles is approximately three times smaller than the number of radial canals. In the southwestern Atlantic, this species was previously known from Patagonian waters and this is the first record from the non-temperate southwestern Atlantic. Additionally, a thorough review of meristic data is provided for this hydrozoan species. (AU)
