The eagle rays Myliobatis hamlyni Ogilby, 1911 and Myliobatis tobijei Bleeker, 1854 are redescribed based on museum specimens and new material from Australia, Indonesia, the Philippines, Taiwan and Japan. These two species are closely related to Myliobatis aquila (L.) from the eastern Atlantic and can be distinguished from each other by a combination of their coloration, meristics, depth preferences and subtle morphometric characters. Myliobatis hamlyni was previously considered to be an Australian endemic, but its distribution is herein extended northward to Taiwan and Okinawa. Myliobatis tobijei was considered to occur southwards from Japan to Indonesia, but its distribution is herein restricted to the western North Pacific, primarily Japan.
基于博物馆标本以及来自澳大利亚、印度尼西亚、菲律宾、台湾和日本的新材料,对鹰魟属的哈氏鹰魟(Myliobatis hamlyni Ogilby,1911年)和托氏鹰魟(Myliobatis tobijei Bleeker,1854年)进行了重新描述。这两个物种与来自东大西洋的鹰魟(Myliobatis aquila (L.))密切相关,可通过它们的体色、可数性状、深度偏好和细微的形态测量特征加以区分。哈氏鹰魟此前被认为是澳大利亚特有种,但本文将其分布范围向北扩展至台湾和冲绳。托氏鹰魟此前被认为分布于从日本向南至印度尼西亚,但本文将其分布范围限制在北太平洋西部,主要是日本。
