This redescription details several features either omitted from, or incorrectly reported in the original description. In particular the shape of the prostomium, which in the original drawings is shown with more rounded lateral margins, and which terminates in a somewhat trilobed anterior margin. Further differences are the shape of thoracic neuropodial lamellae (particularly those of chaetigers 7 and 8, which have triangular postchaetal neuropodial lamellae), the presence of a neuropodial ventral process on chaetiger 9, the presence of small processes at the inner margins of chaetal rows on abdominal chaetigers (DML &amp; VML) and abdominal hooded hooks in two groups,
