Habitat : Sabatieria sanjosensis sp. n. was found in very fine sand (median grain size 6572 µm), 5359 m depth, from San José Gulf (Fig. 1). Etymolog y: From the Spanish word "San José", in reference to the area where it was found. Measurement s: see Table 3. Description.Males: Body cylindrical, tapers slightly towards the anterior end and has a filiform tail end. Cuticle annulated and punctuated. The small punctuations are arranged in transverse rows with lateral differentiations, having larger dots regularly arranged on the lateral fields. Six inner small labial papillae, 6 outer labial setae 0.5 µm long and 4 cephalic setae 45 µm long. Cervical region without somatic setae. Amphids spiralled ventrally towards the centre, with two and a half turns, located at 5 µm from anterior end; 7 µm in diameter (50% bda). Stoma cup shaped, the pharyngeal muscles surround the posterior part of the stoma. Pharynx cylindrical (177210 µm long), posteriorly enlarged. Cardia is small. Ventral gland located at the cardia level and opens through an ampulla at 100136 µm from anterior end. Reproductive system is diorchic, with opposed and outstretched testes, anterior left and posterior right of the intestine. Spicules curved 40 µm (1.3 abd) in chord length. The proximal end has a central cuticularized internal projection, 5 µm long. Gubernaculum formed by one central basal piece 7 µm long, two straight dorsocaudally oriented 24 µm (0.8 abd) apophyses and a distal triangular plate with a lateral alae 10 µm long. Glandular tissue observed situated between spicula and gubernaculum. There is a pair of short precloacal setae 10 µm from the ...
