Antatelson walkeri (Chilton, 1912) Fig. 7 Thaumatelson walkeri Chilton, 1912: 199-200 pl. 1, figs 11-15; Schellenberg 1931: 113; Thurston 1974: 24-25 Antatelson J.L. Barnard, 1972: 312 Antatelson walkeri Krapp-Schickel, 2006: fig. 4a, b ? Thaumatelson cultricauda K.H. Barnard, 1932: 113, fig. 62 Material examined Two specimens 2.5 mm. RRS James Clark Ross , cruise JR144 (BIOPEARL I), stn JR 144 SR-EBS-4-E, Shag Rocks, 53°62'S 40°91'W, 11-04-2006, 201- 205 m, gear: epibenthic sledge, 4 Epi-net. Remarks Comparing the material here with the illustrations of A. walkeri and A. cultricauda (both described as having 3 mm length) there does not seem any reason for accepting two different species. Gn2 of A. walkeri in Krapp-Schickel (2006 fig. 4) is also less widened than in the original description by Chilton, which would be one of the differentiating characters. In A. claudei sp. nov. (see below) there are similar 'pleats' near the dorsal humps as described for A. cultricauda and it may well be that in some specimens these are more visible than in others. The mandibular palp has three clearly visibile articles and also in other mouthparts there is no difference with the illustrations for A. tuberculatum by Andres (1989: 183 figs 4-8, 184 figs 12-14). : Published as part of Krapp-Schickel, Traudl, 2011, New Antarctic stenothoids sensu lato (Amphipoda, Crustacea), pp. 1-17 in European Journal of Taxonomy 2 on page 12, DOI: 10.5852/ejt.2011.2, http://zenodo.org/record/841661 : {"references": ["Chilton C. 1912.
