BioInvasions Atlantic Ocean, Barents Sea and Mediterranean Sea. Here, we confirm its presence Records 9(1): 102–108, https://doi.org/10. in the southern hemisphere using mitochondrial COI, 16S rRNA and nuclear 28S 3391/bir.2020.9.1.14 rRNA gene sequences. These analyses permit us to distinguish it genetically from Received: 17 July 2019 its equally invasive congener, M. arenaria Linnaeus, 1758. We found M. japonica Accepted: 9 November 2019 to be well established in one location on the southeast coast of Tasmania.
