Imogine mediterranea Galleni, 1976

Synonymous: Stylochus mediterraneus Galleni, 1976 .

Material examined. One mature specimen, collected in Los Urrutias (Mar Menor, Murcia). From rocky substrate found between 0.2 to 0.5 metres deep; Fig. 1 (6).

Morphological remarks. The specimen shows very few frontal eyes. The marginal eyes are present only in the anterior half of the body and not in the whole body margin as originally described for Imogine mediterranea ( Galleni, 1976) . However, the internal anatomy of the reproductive organs of I. mediterranea coincides with the original description and figure of Galleni (1976). This difference in the distribution of marginal eyes may be related to the size of the specimen: mature worms are approximately 3 cm long, and this specimen, though mature, is only 12 mm long.

Distribution. Imogine mediterranea has been found in several areas of the northern Mediterranean coast ( Italy: Livorno, La Spezia, Pisa (Galleni 1974) and Liguria ( Wenzel et al. 1992); Croatia: Istria (Bytinski-Salz 1935)) and now in the western Mediterranean coast in Mar Menor.
