Peristichopus papillatus Djakonov, 1952: 125–127 View in CoL , figs 11–14.

Material examined. Syntypes. Russia, SE of Kamtchatka, 52°45'N, 161°41'E, 4100–4200 m, 25 Jul 1946, RAS GoogleMaps (6).

Description. Up to 65 mm long; torpedo-shaped body, some gravel attachments; translucent body wall; prominent small tapered papillae, arising singly on wart-like tubercles in double rows on paired radii, typically 1.5 mm long; ossicles in tentacles, papillae; tentacle ossicles unbranched thick to thin, irregular rods, some swollen centrally, rugose at ends, some bluntly spinous, up to 280 Μm long; papillae ossicles irregular branching rosette-like endplates, irregular rods, some swollen centrally, some spinous, up to 260 Μm long.

Distribution. Russia, SE of Kamtchatka, 4100–4200 m.

Remarks. Djakonov (1952) referred this species to his new genus Peristichopus , which is considered above to be a junior synonym of Pseudostichopus . Amongst Pseudostichopus species, the distinguishing characters of P. papillatus are: the regular paired series of low tubercles and papillae on each of the paired radii; rosette-like “endplate” ossicles in papillae.
