Sabatieria parapraedatrix sp. n. (Figs 6–7, Table 2) Material examined. Holotype male (NIWA 865989), collected 6 April 2007, southern flank of 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. Two male and two female paratypes (NIWA 865990), same data as holotype. Etymology. The species name refers to the species S. praedatrix, which is similar to the new species. Description. Male Body cylindrical, slender, tapering slightly towards anterior extremity. Cuticle with transverse rows of dots, lateral differentiation consisting of rows of larger dots. Faint striations also present throughout body, situated 1.5 µm apart, most visible near head region. Striations appear restricted to epicuticle, are mostly visible in dorsal and ventral regions, and result from fusion of every second lateral row of dots. Two dorso- and two ventro-lateral rows of short, sparse somatic setae, some associated with inconspicuous, elongated hypodermal glands (Fig. 7 A). Head slightly set-off by depression at level of cephalic setae. Six inner labial papillae, six outer labial papillae, and four short cephalic setae. Anterior portion of buccal cavity cup-shaped, posterior portion narrow. Fovea amphidialis spiral, 2.0– 2.5 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 short, 5–8 µm long. Nerve ring near middle of pharynx. Secretory-excretory system present, cellular body of ventral gland at level of intestine, pore situated 0.5 –1.0 cbd posterior to nerve ring. Intestine wall with numerous small, colourless granules, with differentiation of rounded cells containing more densely packed granules in ...
