Thelepus cincinnatus (Fabricius, 1780) (Figs 3–4) Amphitrite cincinnata Fabricius 1780: 286. Thelepus cincinnatus. Malmgren 1866: 387–388, Pl. XXII, Fig. 58A–D.? Holthe 1986a: 140–142, Fig. 63a–c.? Jirkov 2001: 526, Fig. Thelepus cincinnatus 1–6.? Jirkov 2018: 38–43, Figs 2, 3 A–D, 11B. Material examined. Syntypes (NRM 1270): 3 specs, coll. W Greenland, Pröven, 36.4 m, solid rock, 72 o 23’N 56 o 00’W, by O. Torell. Syntype 1: 100 mm long, 7 mm wide, 71 segs, complete, missing all buccal tentacles and most branchial filaments, with notopodia until segment 49, apparently regenerating thereafter, with shorter, thinner and densely packed segments, bearing neuropodia and lacking notopodia. Syntype 2: 95 mm long, 6 mm wide, incomplete, 40 segs, all with notopodia. Syntype 3: 67 mm long, 6 mm wide, incomplete, 35 segs, all with notopodia. Additional material examined. NRM 103980: 4 specs. (originally 5, but one belongs into the Terebellidae sensu stricto, not Thelepodidae), coll. Sweden, Bohuslän, Gullmarsfjord, Löken, by L.

NRM 103981: 4 incomplete specs and 2 mid-body fragments, coll. Sweden, Bohuslän, Gullmarsfjord, Löken, by L. Orrhage, 21 Jul 1980; all with notopodia until end of fragments and in excellent state of preservation; longest spec. with 36 segments, 24 mm long, 3 mm wide. NRM 103982: 1 complete spec. and 4 midbody fragments without an anterior end, coll. Sweden, Bohuslän, Gullmarsfjord, Löken, by L. Orrhage, 21 Jul 1980; complete spec. in excellent state of preservation, 60 segs, notopodia until seg. 32; not clear if mid-body pieces belong to the same species or even to a single animal. NRM 103983: 2 specs and a midbody piece, coll. Sweden, Bohuslän, Gullmarsfjord, Löken, by L. Orrhage, 21 Jul 1980; both specs incomplete, in good state of preservation. Description.
