Remark: The species was placed in the genus <i>Bathyphasma</i> Gilbert, 1896 by Balushkin (2012), genus he resurrected on the basis of a few characters. He was followed by authors thereafter but with no supplementary evidence. Orr et <i>al.</i> (2019) did not support the resurrection from their phylogeny, on the basis of a lack or morphological synapomorphies with other sister-species, which we follow in FishBase and WoRMS.
