Macrostylis setulosa Mezhov, 1992 urn:lsid:zoobank.org:act:8C216677-AD60-4F8B-B55B-34627ABB7479 Macrostylis setulosa Mezhov, 1992; pp. 83–87, Fig. 1. Type fixation. Holotype: non-ovigerous female, 3.2 mm, Mc-1274, by original designation. Type material. Holotype: non-ovigerous female, Mc-1274, with 3 stage III mancae; paratype: non-ovigerous female, 2.8 mm, Mc-1275. All material deposited at the Zoological Museum of the Moscow State University. Type locality. Southern Ocean, Scotia Arc, South Sandwich Islands with R/V Akademik Kurchatov , cruise 11, station 880, 57° 07.4’ S, 26° 40’ W; 757 m depth; by means of the bottom sampler "Okean". Type material - Remarks. The paratype material collected at stations R/V Akademik Kurchatov 927 originate from a very different locality and depth. Type material was not available for comparison but there is a possibility that they are different species. Because of that, the information given by Mezhov about male characters were excluded here and corresponding stations are listed below as further records instead of type locality. The type locality is hence restricted to the locality of the holotype. Further records. R/V Akademik Kurchatov , cruise 11, station 927, 56° 08.4’ S, 52° 40’ W; 1,660 m depth. R/V Dm.
