| Abstract |
A new species of Dialychone, D. egyptica sp.n. (Sabellidae) is described from the Mediterranean Coast of Egypt. The material was collected from soft bottom at 60 m depth. It is unique among the genus in having an abdominal glandular ridge on chaetiger 13. The new species is also characterized by having pygidial cirrus, medium sized radiolar tips and long radiolar pinnules, anterior peristomial ring lobe incised and exposed beyond collar, a trapezoidal ventral collar shield, and paleate chaetae with long mucro. The distributions of Dialychone collaris (Langerhans, 1880), D. usticensis (Giangrande et al., 2006), D. dunerificta (Tovar-Hernández et al., 2007), and Paradialychone gambiae (Tovar-Hernández et al., 2007) along the Mediterranean coast of Egypt are also presented. P. gambiae reported for the first time in the Egyptian coasts, while D. dunerificta was previously recorded as Chone duneri Malmgren, 1867. |
