5. Ventrally white speckles strongest between chaetigers 8–13 (associated with mid-ventral line) continuing into abdomen, with additional patches around chaetigers 2–5. Rose Bengal staining dorsally noticeable between chaetigers 2–5 around parapodia (not medially), strongest on 3–4, but also present between 4–5 (if present, seen as sparse speckled areas). Small interparapodial patches are present between chaetigers 6–7, and stronger patches between chaetigers 8–9. Abdominal interparapodial areas showing stain with Rose Bengal, as do the white speckled areas of the venter.

was originally described from one specimen in which pigment in the posterior thorax was not observed. However, the presence of thoracic pigment amongst the Persian material was sporadic. The fact that pigment in Persian material was pale (never forming a distinct band) even in material collected more recently, and was only present on a small number of specimens suggests that this is a variable character within this species. Observation of live or fresh material may help to resolve this. The

possessed small ventral processes on the neuropodia of chaetiger 9. These were not always observed in the Persian material, even on different sides of the same chaetiger. However even when present, they are minute and often difficult to discern. Their presence/conspicuousness may well be related to size of a specimen. This may also be resolved in the future by the examination of additional material.
