Summary: | Macrostylis scotti n. sp. (Figs 2–10) urn:lsid:zoobank.org:act: 8 EBFDE 96 -E 5 CB- 4 D 62 -A 56 D- 8 E 23 B 910 EDC 7 Etymology. The name “s cotti” is dedicated to the British explorer Robert Falcon Scott CVO, in order to mark the 100 th anniversary of his heroic trial to be the first person to reach the geographic South Pole. He reached the pole second, after Roald Amundsen, and died on this ill-fated Terra Nova Expedition around the 29 th March 1912. Type fixation. Holotype (Figs 2, 3): adult male, 5.4 mm, ZMH K- 42990, designated here. Type material examined. Holotype: adult male, 5.4 mm, ZMH K- 42990, used for the illustration of the habitus and DNA studies. Paratypes: adult male, 5.1 mm, ZMH K- 42991, dissected for illustrations of appendages and habitus as well as DNA studies; non-ovigerous female, 5.3 mm, ZMH K- 42992, dissected for illustration of appendages and DNA studies. Type material - Remarks. The holotype is comlplete except for posterior pereopods that have been removed from one side for DNA studies; complete holotype and carcasses of paratype are conserved in 96 % EtOH, dissected parts are mounted on slides using Euparal. Type locality. Collected 04th January 2008 from the slope of the seamount Maud Rise. This is located off Queen Maud Land on the Antarctic continental slope. Samples were taken during the ANDEEP-SYSTCO project with R/V Polarstern, station ANTXXIV- 2 039- 17: start trawl at 64 ° 28.77 ’ S, 2 ° 52.69 ’ E; 2,152 m depth; end trawl at 64 ° 28.66 ’ S, 2 ° 53.14 ’ E; 2,153 m depth. Diagnosis. Body heavily calcified, cuticular setules absent. Tergal plates laterally projecting below coxae, coxal articulations ventrally or medioventrally. Ventral spines keeled. Pereonites 1–5 in male with rows of long simple setae along posterolateral margins. Pereonite 3 posterolateral margin not produced posteriorly. Pereonites 3 and 4 ventral spines absent. Pereonite 4 width exceeding pereonite 5 width. Pereonite 6 posterolateral margin rounded. Pereonite 7 ventral spine present, small. Female ... |
