Genus Terebellides Sars View in CoL , emended by Schüller and Hutchings 2013
Type species: Terebellides stroemii Sars, 1835 Diagnosis. Trichobranchidae with compact prostomium fused to free frontal edge of the peristomium. Peristomium forming lips, upper lip typically hidden, lower lip expanded. Branchial stems fused, branchiae forming single, lamellate structure on mid-dorsum, made up of 1 to 4 lobes, sometimes an anterior prolongation of lobes (fifth lobe) present. Eyespots absent. Lateral lobes absent. Thorax with 18 pairs of notopodia from segment III and neuropodia from segments VII (chaetiger 5) or segment VIII (chaetiger 6) to pygidium. Notochaetae all capillaries with varying degrees of ornamentation. First, and sometimes second thoracic neuropodia with smooth, geniculate hooks, subsequent thoracic ones with denticulate hooks. Abdominal uncini avicular.
Remarks. Parapar et al. (2011) found minute teeth forming a capitium on geniculate chaetae in all Icelandic species ( T. stroemii Sars, 1835 , T. gracilis Malm, 1874 , T. atlantis Williams, 1984 and T. bigeniculatus Parapar, Moreira and Helgason, 2011 ). We consider the characterisation of geniculate chaetae as “smooth” in the current diagnosis as doubtful.
