Type locality and habitat. All specimens were collected from the Chukchi Sea (52 m water depth). Station CC 1: 67.6722°N, 168.9562°W. Median grain diameter: 5.35 Md Φ, Sand: 33.34%, Silt: 58.02%, Clay: 8.63%. Etymology. This species is named after its body is large and thick. Measurements. Table 4. Description. Male. Body cylindrical, tapering slightly towards both extremities. Cuticle with transverse rows of dots, lateral differentiation consisting of larger, irregularly-spaced dots. Two dorso- and two ventro-lateral rows of short, sparse somatic setae. Three crowns of anterior sensilla: six inner labial papillae, six short but distinct outer labial setae and four short cephalic setae. Buccal cavity cup-shaped. Amphideal fovea spiral with 2.5–3.25 turns, located immediately posterior to cephalic setae. Pharynx gradually swelling towards posterior part, not forming true bulb. Nerve ring 169–186 µm from anterior end of body, at 49–56% of the pharyngeal region length. Excretory pore 188–210 µm from anterior end of body, at 57–64% of the pharyngeal region length. Tail 314–367 µm long, conico-cylindrical with four rows of sparse short caudal setae and three short terminal setae. Reproductive system diorchic with outstretched testes. Anterior testis to the left of intestine, posterior testis to the right of intestine. Spicules paired, equal, arcuate, equal to 1.5–1.9 cloacal body diameters in length, and with central cuticularised projection (lamella) extending from proximal end to one third of spicule. Gubernaculum with 70–84 µm long, paired, straight apophyses. Rectal gland surrounds gubernacular apophyses and distal portion of ...
