Corrigia obscura sp. n. was found in the pancreatic ducts of a black duck, Anas rubripes. This is the first record of the genus Corrigia from an anseriform bird and from North America. Corrigia obscura differs from other Corrigia spp. by having a greater relative forebody length and greater relative body width. Noticeable hyperplasia and sloughing of the wall of the pancreatic ducts were associated with this infection.
新种暗色隐孢子虫(Corrigia obscura sp. n.)在黑鸭(Anas rubripes)的胰管中被发现。这是隐孢子虫属在雁形目鸟类以及在北美洲的首次记录。暗色隐孢子虫与其他隐孢子虫物种的不同之处在于其相对前体长度更长且相对体宽更大。这种感染伴有胰管壁明显的增生和脱落。
