Abstract

<p>The burrowing sea anemone, <i>Metedwardsia akkeshi</i> (Uchida, 1932), which was originally described from Lake Akkeshi, Hokkaido, and is the only species in the genus <i>Metedwardsia</i> Carlgren, 1947, was again collected from Akkeshi in 2015 and 2017, many decades after it was first described, and was also collected from Lake Furen and Lake Onne-to, both in Hokkaido, in the 2010s. Although the original description of <i>M. akkeshi</i> was comprehensive, it lacked information about the cnidom and detailed figures of each body part. Here, we re-describe <i>M. akkeshi</i> after thorough analyses of the newly collected specimens in detail, and based on these topotypic specimens, we also re-diagnose the genus <i>Metedwardsia</i> by providing more detailed information about characteristic morphological features and the cnidom. In addition, we discuss the possible location of "Akkeshi Cove", the site where <i>M. akkeshi</i> was originally collected by Tohru Uchida.</p>
