Sphaerosyllis thomasi San Martin 1984 

Sphaerosyllis thomasi  San Martín, 1984b: 250, fig. 59; 2003: 199, figs 103-104; Arvanitidis 1994: 80; Çinar 1999: 163, fig. 4.60.

Material examined.

Haifa Bay, Israel: ALA-IL-7 (2 ind.) [coll. 11.10.2009].

Type locality.

Balearic Islands (western Mediterranean Sea).


Mediterranean Sea: WB, CB, AD, AS, LB. New record for the Israeli coast.


Shallow subtidal depths, in muddy to coarse sands, among Posidonia oceanica  rhizomes.


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).
