Material examined. St. 1: 1 individual.

Distribution. Mediterranean Sea, Atlantic Ocean, Red Sea (San Martín 2003) and Pacific Ocean (San Martín et al. 2008).

Remarks. The specimen agrees well with the description given by San Martín (2003). In the Mediterranean Sea this species is common in infralittoral algal assemblages suffering sediment deposition, it is less common on muddy bottoms and among circalittoral and bathyal white coral reefs. E. tuberculata has been reported from the surface down to 760 m depth (San Martín 2003), even though it is rare in deep environments. Following Nygren (2014) hypothesis on Syllidae species reported to have extremely wide geographical distributions and generalist environmental requirements, E. tuberculata could actually represent a species complex.
