Abstract
In this paper, we describe the first association of the ostreid species Ostrea puelchana d’Orbigny, 1842, as new epibiont in Eriphia gonagra (Fabricius, 1781), with material collected in Northeastern Brazil. The specimens of E. gonagra were collected manually in November of 2020 during the low tide in the Barra de Catuama beach, State of Pernambuco. Among 10 specimens collected, only one adult male showed the presence of two commensal specimens of O. puelchana adhered in the epibranchial and antero-lateral regions of the basibiont (right side). The presence of the epibiont O. puelchana on the new host E. gonagra expands the range of the crustacean species potentially used as hosts by this oyster along the Brazilian coast.
Keywords: marine invertebrates, biological interactions, Pernambuco, commensalism, beachrocks.
本文描述了Ostrea puelchana d 'Orbigny, 1842年作为新表观生物首次与巴西东北部采集的材料联系在一起。gonagra E.的标本是在2020年11月伯南布哥州Barra de Catuama海滩退潮期间人工采集的。在采集到的10个标本中，只有1只雄成虫在基生体的鳃外和前外侧区域(右侧)发现了2个共生的棘球棘虫标本。表皮生物O. puelchana在新寄主E. gonagra上的存在扩大了巴西沿海这种牡蛎可能用作寄主的甲壳类物种的范围。关键词:海洋无脊椎动物，生物相互作用，伯南布哥，共生，滩岩
