Abstract
Many specimens of Syllidae were sampled during several collection trips to different parts of Egyptian
coastline from North to West. Most of these are typical meiofaunal species belonging to the subfamilies
Exogoninae, Eusyllinae and Syllinae. In this paper, 9 species belonging to subfamily Exogoninae, genera Exogne,
Sphaerosyllis and Brania are described. Two of them (Sphaerosyllis giandoi Somaschini and San Martín,1994 and
Exogone (Parexogone) gambiae Lanera, Sordino & San Martín, 1994) are endemic to the Mediterranean, while
Brania arminii Hartmann-Schröder, 1971 is circumtropical species. Sphaerosyllis sp. San Martín, 2003,
Sphaerosyllis glandulata San Martín, 1991 and Sphaerosyllis sandrae Álvarez and San Martín, 2008 are amphiAtlantic, while, Prosphaerosyllis fujianensis Ding & Westheide, 2008 and Exogone (Parexogone) sexoculata
Hartmann-Schröder, 1979 are Indo Pacific species, they seem to be Lessepsian migrant species.
