| Summary: | Macrostylis vinogradovae Mezhov, 1992 urn:lsid:zoobank.org:act:7C4763BD-9260-4169-8B1F-F666097CB142 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. Pereonite 3 posterolateral margins not produced posteriorly. Pereonite 4 wider than pereonite 5, lateral margins convex, posterolateral margins produced posteriorly, tapering, posterolateral setae spine-like, robust. Pleotelson ovoid, waist present, setal ridges visible. Ischium dorsal lobe triangular; apex with 1 prominent seta; distally with no seta. Operculum elongate, subsimilar pleotelson length, distally tapering, ventrally keeled, apical width smaller 0.50 operculum width, apical setae short. Description female. Body. Length 2.6 mm, subcylindrical. Ventral spines. All spines acute. Pereonite 1 spine prominent. Pereonite 3 spine small, closer to anterior segment border. ... |
