Paratype, ZMMU Lc- 37462, one dissected specimen, same locality and collectors as holotype, 19.08. 2008. Type locality. NW Pacific, SE Kamchatka, Starichkov Id., 18– 26 m. Etymology. This species is named in honour of Vyacheslav G. Shipilov, captain of the boat “Chaika” in recognition of his generous help in organizing scuba diving. Description. External morphology. The length of the holotype is 23 mm and width 11.5 mm (Fig. 9 A–B). The length of 20 living specimens ranged from 8 to 23 mm, the width ranged from 4.5 to 11.5 mm. The consistency of living animals is rather soft. The notum is moderately broad, rounded in front and posteriorly. The rhinophores are long and retracted into sheaths with smooth edges, except for 5–6 tubercles of various size that are connected with edge of each sheath (Fig. 9 D). The rhinophoral sheath edges are capable of some contraction in living specimens. There are 11–14 rhinophoral lamellae. The clavus of the rhinophore has a low ridge posteriorly. The notum is densely covered with inflated cylindrical or almost globular tubercles on a short stalk. Tubercles in the central notal area are somewhat wider and more globular than those at the notal edge. Larger tubercles are regularly ...
