Summary: | Deima validum validum Théel, 1879 (Fig. 4) Deima validum Théel, 1879: 5, figs 36–38 Deima validum validum . Hansen, 1975: 17 –23, fig. 1, pls 11 (fig. 1), 13 (figs 1–2), [synonymy] Deima fastosum Théel, 1879: 5 –6, figs 1–3 Deima blakei Théel, 1886b: 1 –2, figs 1–2 Deima atlanticum Hérouard, 1898: 88 –89, figs 1–2 Deima mosaicum Ohshima, 1915: 233 –234 Material. M 48/1333: 1 specimen (ZSM 20043072). M 48/1339: 1 specimen (ZSM 20020018). M 48/1343: 1 specimen (ZSM 20043071). Remarks. The taxonomy, morphology and distribution of this subspecies has been described in detail by Hansen (1975). It is characterised by: 10–13 pairs of ventrolateral tube feet in single rows; midventral tube feet absent or rarely represented by a reduced preanal pair; dorsal papillae 5–10 pairs; ventrolateral papillae 3–7 pairs; calcareous deposits are perforated plates, usually large and multilayered; dorsal plates 1.5–7.0 mm in diameter, ventral plates 0.5–4.0 mm. The investigated specimens fit with this diagnosis. The largest specimen (86 mm in length) has a single (?) small preanal tube foot, while there are no preanal tube feet present in the other specimens. This is the second record of this species for the South Atlantic Ocean and the known depthrange is increased from 4820 m to more than 5400 m. Distribution. (Fig. 4) This subspecies probably has a cosmopolitan distribution, except for the Arctic and Southern Ocean, 724–5426 m (Deichmann 1940; Grieg 1921; Hansen 1975; Hérouard 1902, 1923; IFREMER BIOCEAN; Koehler & Vaney 1905; Ohshima 1915; O'Loughlin 1998; Sibuet 1977; Sluiter 1901; Théel 1882, 1886b; herein).
