Sabatieria spiculata sp.nov. (figure 2 and 3) Description Studied material: 6 male; 4 female Type material: Male hollotype MNRJ 305; female allotype MNRJ 306; 5 males 46–50 NM LMZOO­ UFPE; Three females 51–53 NM LMZOOUFPE. Type locality: Campos Basin (Rio de Janeiro, Pernambuco, Brazil). It was found at 750 and 1650 meters depth, in silt­clay sediments. Measurements: see table 2. Etymology: The specific name spiculata refers to the long and sligth spicule. Male: Cylindrical body, medium­sized, tail short with cylindro­conical shape. Punctated cuticle with transversal rows of dots and lateral differentiation with larger and wider spaced punctations, specially in the tail region. Rounded and attenuated head with anterior sensilla arranged in three crowns: six minute internal labial sensilla, six external labial setae and four cephalic setae. Somatic setae, short. Amphidial fovea spiral, with three turns. Buccal cavity cup­shaped, with diminute dorsal teeth. Pharynx clavate, gradually expanding towards to the posterior end, but without distinct bulb. Cardia short, pear shaped. Nerve ring slender located at the middle of pharynx and anterior to secretory­excretory pore. Ventral gland opposite posterior end of pharynx and beginning of intestine; system diorchic; opposed and outstretched testes. Anterior testis situated on the left of the intestine and the posterior one on the right side. Spicule paired with the same length equally wide and slightly curved ventrally; proximal half with mid­septum (each spicule has inside the core sensilla). Several glandular cells are arranged around the spicules. Small gubernaculum with narrow apophysis. Minute porelike precolacal supplements and precloacal setae. Spermatozoa oval, elongated, showing some striation. Conical tail with three caudal glands, ending in a spinneret. Two caudal setae. TABLE 2. Measurements (µm) of Sabatieria spiculata sp.nov. Female: Females are quite similar to males, although some minor morphological differences are observed. Total body length and head ...
