Macrostylis vinogradovae Mezhov, 1992 urn:lsid:zoobank.org:act: 7 C 4763 BD- 9260 - 4169 - 8 B 1 F-F 666097 CB 142 Macrostylis vinogradovae Mezhov, 1992; p. 87, Fig. 2. Type fixation. Holotype: non-ovigerous female, 2.6 mm, Mc- 1279, by original designation. Type material. Holotype: non-ovigerous female, Mc- 1279, DM station 4084 -II; paratype: female fragment, 1.2 mm, Mc- 1280, DM station 4084 -I. All material deposited at the Zoological Museum of the Moscow State University. Type locality. Southern Ocean, southeastern Weddell Sea, off Kapp Norvegia, Dronning Maud Land, with R/ V Dm. Mendeleev, cruise 43, station 4084 -II, 70 ° 53.17 ’ S, 15 ° 04.51’ W; 2,925 m depth; by means of the bottom sampler "Okean". Type material - Remarks. Only the holotype is complete and the only other specimen is a strongly-damaged fragment of which substantial parts are missing. Further, the paratype was collected from a very different depth (bathyal vs. abyssal). An allocation of both specimens to the same species is therefore put in doubt. The type locality is consequently restricted here to the collection locality of the holotype. Further records. Southern Ocean, southeastern Weddell Sea, off Kapp Norvegia, Dronning Maud Land, with R/V Dm. Mendeleev, cruise 43, station 4084 -I, 70 ° 40.6 ’ S, 15 ° 47.8 ’ W; 4,335 m depth; by means of the bottom sampler "Okean". Modified diagnosis.
