Sabatieria bathycopia sp. n. (Fig. 19–21, Table 4) Material examined. Holotype male (NIWA 866001), collected 6 April 2007, southwest Chatham Rise (1240 m water depth), 44.4864 °S, 177.1407 °E. Characteristics of surface sediment layer (0–5 mm): mostly silt/clay (82.9 %), with very fine sand (9.4 %), and fine sand (7.7 %); calcium carbonate content: 38.4 %; total organic matter content: 1.9 %; chloroplastic pigment concentration: 3501 ng /gDW sediment. Three male and five female paratypes (NIWA 866002), same data as holotype. Etymology. The species name is derived from the latin bathys (= deep) and copia (= abundance, plenty), and refers to the common occurrence of this species at sites characterised by high food availability on the continental slope of New Zealand (D. Leduc, unpublished data). Description. Male Body relatively stout, cylindrical, tapering slightly towards both extremities. Cuticle with transverse rows of dots, lateral differentiation consisting of rows of slightly larger dots. Two dorso- and two ventrolateral rows of short, sparse somatic setae, some associated with rounded hypodermal glands (Fig. 21 C). Head slightly set-off by depression at level of cephalic setae or slightly posterior to cephalic setae. Inner labial papillae indistinct, six outer labial papillae and four short cephalic setae. Anterior portion of buccal cavity small, cupshaped, lightly cuticularised and with minute teeth-like projection at base, posterior portion narrow. Fovea amphidialis spiral, 2.75 –3.0 turns, located immediately posterior to cephalic setae. Marginal tubes arising from base of buccal cavity and extending to posterior end of pharynx. Pharynx gradually swelling towards posterior, not forming true bulb, cardia 15 µm long. Nerve ring at about middle of pharynx length. Secretory-excretory system present, with three glands situated just posterior to pharynx, one situated ventrally and two laterally, each with separate duct and opening through common pore situated 0.5 –1.0 cbd posterior to nerve ring.
