Euchone rubrocincta Sars, 1861

Chone rubrocincta Sars 1861 .

Remarks

This taxon is the only Euchone species reported by Fauvel (1927) for the Mediterranean area. The first record in the Mediterranean was that of Lo Bianco (1893) for the Gulf of Naples. The taxon was successively reported by Vatova (1949), Katzmann (1973), and Pozar-Domac (1978) for the Adriatic Sea, and by Albertelli et al. (1983) for the Ligurian Sea. The specimens present in our personal collection, from the Gulf of Salerno (Tyrrhenian Sea), are very badly preserved and cannot be re-described. According to the original description, the species should be easily recognizable on account of the narrow hooded inferior thoracic notochaetae similar to the superior ones ( Figure 5E ), and the anal depression formed by 11 chaetigers.

Habitat

Fine sand substrata.

Distribution

North Sea, Atlantic ( Ireland), Mediterranean Sea.
