Seven new species and one new species record of Sabatieria (Nematoda: Comesomatidae) from the continental slope of New Zealand
Sabatieria is the most abundant nematode genus on the upper continental slope of New Zealand but no Sabatieria species have yet been recorded/described from the region’s deep-sea habitats. The present study describes seven new and one known species of this genus from the continental margin of New Ze...

Sabatieria is the most abundant nematode genus on the upper continental slope of New Zealand but no Sabatieria species have yet been recorded/described from the region’s deep-sea habitats. The present study describes seven new and one known species of this genus from the continental margin of New Zealand. S. bitumen Botelho et al. 2007 was originally described from the South Atlantic Ocean, and is recorded from the first time in the Pacific Ocean. Sabatieria challengerensis sp. n. is characterised by a combination of short cephalic setae, large fovea amphidialis with 3 turns, short arcuate spicules without distal hook, and short tail with cylindrical proximal portion and blunt, rounded distal portion. Sabatieria parapraedatrix sp. n. is characterised by having a slender body, cuticle with striations resulting from fusion of every second lateral row of dots, fovea amphidialis with 2.0–2.5 turns, spicules with distal hook, and short conico-cylindrical tail. Sabatieria bubulba sp. n. is characterised by the presence of a large muscular pharyngeal bulb, secretory-excretory system with large ventral gland at level of intestine and with cuticularised pore opening. Sabatieria exculta sp. n. is characterised by having a slender body, cuticle with faint annulations resulting from fusion of every second or third lateral row of dots, short cephalic setae, a large ventral gland, and long, narrow gubernacular apophyses.
