Eusyllis assimilis Marenzeller, 1875 View in CoL

Eusyllis assimilis Marenzeller, 1875: 158 View in CoL , pl. 3, Fig. 2 View FIGURE 2 .— Fauvel (1923): 294, Figs. 112a–g.— San Martín (2003): 114, Figs. 52, 53.— San Martín & Hutchings (2006): 273, Figs. 10 A–J, 11 A–F, 12 A –C.

Eudontosyllis aciculata Knox, 1960: 105 View in CoL , Figs. 113–117.

Eusyllis japonica Imajima & Hartman, 1964 View in CoL : 111,112, Figs. 25 a–g.

Eusyllis irregulata Imajima, 1966: 91 View in CoL , Figs. 28 a–i.

Material examined. Eusyllis assimilis : ( MNCNM 16.01/3727, 4367, 7297, 8637 a 8673); Eusyllis japonica : Paratype ( NMNST 82).

Distribution. Eastern Atlantic Ocean (English Channel to South Africa), Western Atlantic Ocean ( México), Mediterranean Sea, North Pacific Ocean ( Japan, Australia, New Zealand).

Habitat. Calcareous algae, photophilic and sciafilic algae; Posidonia oceanica meadows; coralligenous concretions; inside sponges; in red coral and Dendrophyllia ramea .

Remarks. Apparently cosmopolitan. Some Mediterranean and Pacific specimens have a complete denticled pharyngeal arc.

Eusyllis phosphorea Verrill, 1874: 20 View in CoL , 39, pl. 7, Fig. 2 View FIGURE 2 .

Material examined. Eusyllis blomstrandi : Type ( SMNH 2346); ( MNCNM 16.01/11218 and 11219); Eusyllis monilicornis : ( SMNH 2435); Eusyllis phosphorea : ( YPMNH 48975, 48976); Eusyllis tubifex : ( NHML 85.12.1.141 and 1921.5.1.1117–1126).

Distribution. Arctic, Pacific ( Japan) and North Atlantic Oceans, Mediterranean Sea, Adriatic Sea and Red Sea.

Habitat. Photophilic algae; Posidonia oceanica rhizomes; detritic sand and gravel; inside sponges and coralligenous concretions.

Remarks. Originally described as Syllis tubifex by Gosse (1855), it was transferred by McIntosh (1908) to Eusyllis . However, the McIntosh’s specimens were morphologically identical to E. blomstrandi Malmgren, 1867 . Accordingly S. tubifex is older than E. blomstrandi , which would become the senior synonym. However, it is not possible to assess this fully, as Gosse’s description is quite incomplete and the material is lost. So we retain E. blomstrandi as a valid name, and S. tubifex as a possible synonymy, according to the principle of stability (International Commission on Zoological Nomenclature, 1999).
