Salmacina chilensis .— Nogueira and ten Hove, 2000: 158–159, tab. 1–2 (discussion of the genus).

Diagnosis. Tube white, thin. Branchial crown with 9–10 radioles per lobe; radiole tip not inflated. Opercular peduncle or operculum absent. Thorax with seven chaetigers. Collar with fin-and-blade chaetae, with proximal denticulate expansion separate of distal limbate zone ( Fig. 10F), with numerous teeth ( Fig. 10G). All thoracic chaetigers (except collar segment) with “ Apomatus ” chaetae. Thoracic uncini saw shaped, with eight rows of teeth and two teeth in each row. Abdomen with 36 chaetigers.

Habitat. Depth: 282 m. On the brachyuran crab Lophorochinia parabranchia .

Distribution. Only known from northern Chile ( Gallardo 1969).

Taxonomic remarks. According to Nogueira and ten Hove (2000), Salmacina chilensis is very different to any other species of Salmacina , in terms of the large number of radioles present. Moreover, the arrangement of the teeth in the fin-and-blade collar chaetae ( Figs 10F–G) “is rather more reminiscent of Protis or Chitinopoma , than of Salmacina ” ( Nogueira & ten Hove 2000: 157).
