Hyalopomatus jirkovi Kupriyanova, 1993 a (Fig. 5 A–B, H) Hyalopomatus jirkovi Kupriyanova, 1993 a: 147 –148, fig. 1. Material examined . Type material. SIO: R/V “ Vityaz ” Stn. 5593, 45 ° 38 ’N, 152 °02’E, 1050 m, 12 Aug 1966 (holotype and paratype). Newly examined material. SIO: R/V “ Vityaz ” Stn. 4131, 55 º47.6’N, 145 º19.7’W, 3949 m, trawl, 9 Nov 1958 (4 specs). Description. Tube : Tubes white, smooth, attached to the Cidaris throughout its length, circular in cross-section, some indication of interruptions in calcium carbonate secretion (see Sanfilippo 2009) along the tube. Branchial crown: 8–10 pairs of radioles, not joined by inter-radiolar membrane. Bases of branchial radioles short. Branchial eyes not visible in preserved material. Stylodes absent. Peduncle : inserted as 1 st dorsal radiole on left side of crown, thin, smooth, circular in cross-section. Constriction present. Pair of lateral wings proximal to opercular bulb and pseudoperculum absent. Operculum : semi-transparent elongated vesicle with slightly differentiated darker distal cap (Fig. 5 H). Collar and thoracic membranes : collar four-lobed, with ventral lobe additionally sub-divided into two round lobes by a deep incision; ventro-lateral lobes twice as long as latero-dorsal lobes (Fig. 5 A, B). Thoracic membranes reaching up to 3 rd chaetiger, of even width throughout (Fig. 5 A, B). Thorax : with six thoracic chaetigers, five of which uncinigerous (Fig. 5 A, B). Collar chaetae simple capillaries and special fin-and-blade chaetae, with wide blade continuing without a gap in proximal fin made of numerous small teeth. Remaining notochaetae with short wide distal limbate blade. Apomatus chaetae absent. Thoracic uncini rasp-shaped, with about 20 teeth in profile view, arranged in 3–4 transverse rows, and with elongated and flattened anterior peg (SEM details of peg structure not available). Abdomen : abdominal uncini similar to thoracic uncini but smaller with about 20 teeth in profile view. Straight, almost capillary (distal limbation very narrow) abdominal chaetae (SEM details not available). Colour : unknown. Remarks . This is the second record of this species previously known only from two specimens (the type material) collected from the Kurile-Kamchatka Trench. Hyalopomatus jirkovi clearly differs from all described species of Hyalopomatus by the structure of the collar with ventral lobe sub-divided into two lobes by deep incision at midline. Distribution .
