Distribution

Boreal North Pacific, Antarctica (?), 54–2550 m, possibly below 3000 m.

Remarks

Uschakoviella echinophora has been recorded only once in the Southern Ocean: north of the South Orkney Islands, 59°48ʹ S, 45°06ʹ W ( Watling & Holman 1981). These authors do not give the depth of their record. The Google Earth depth for that position is 3553 m [Google Earth accessed on 27.09.2016], suggesting a depth between 3000 and 4000 m. The specimen, which was a juvenile, is lost ( Coleman 2007). The real identity of the Antarctic specimen is questionable ( De Broyer et al. 2007). Klages (1991: 51) also listed a Uschakoviella sp. from the eastern Weddell Sea, without giving precise information on his material. It is usually assumed that Uschakoviella echinophora echinophora Gurjanova, 1955 and U. e. abyssalis Gurjanova, 1955 are the same species. However, examination of Gurjanova’s (1955) drawings reveals slight morphological differences in the basis of pereiopod 7 and there might therefore be two taxa involved.
