Remarks.

The examined specimens agree well with the description of San Martín (2003), especially in the chaeteal structures, but in the Israeli specimens the dorsal cirri are as long as parapodial lobes in posterior and midbody chaetigers and only slightly shorter than parapodial lobe in anterior chaetigers (dorsal cirri shorter than parapodial lobe in San Martín’s (2003) description).
