Ostrea puelchana (D'Orbigny 1842): a new host of Tumidotheres maculatus (Say, 1818) in northern Patagonia, Argentina

Tumidotheres maculatus has been reported as a commensal of Mytilus platensis and Atrina seminuda and suggested as a parasite of Aequipecten tehuelchus in San Matías Gulf (SMG). The native flat oyster, Ostrea puelchana, has been studied in SMG for decades, and no crab-oyster association has been repo...
