Type locality and distribution

In the original description, Willemoes-Suhm (1874) did not indicate which of the two potential localities near Crozet Island had yielded the new species. According to the station list of the Challenger Expedition ( Murray 1895), this species was encountered only at station 147, i.e., 46°16ʹ S, 48°27ʹ E between Marion Island and Crozet Island, bottom (= trawling) depth 1600 fathoms (2926 m). This position is therefore regarded as the type locality. According to Hernández-Payán & Hendrickx (2020) and Daneliya (2023) this species is known from the Arctic, Atlantic, Mediterranean, Pacific and the Southern Ocean at depths of 728–7200 m. The ANDEEP records are within previously known distribution ranges.
