A study of specimens belonging to the genus
Syllis (s.l.) (Polychaeta, Syllidae), principally from Cuba, and also the Gulf of Mexico, Florida and North Carolina, was carried out. The taxonomy of the genus is discussed. The following new species are described:
S. alosae,
S. sardai,
S. barbata,
S. ortizi,
S. danieli, and S.
maryae; the following species are new to the Cuban fauna:
S. corallicoloides Augener, 1922;
S. alternata Moore, 1908;
S. garciai (Campoy, 1982);
S. broomensis (Hartmann-Schröder, 1979);
S. beneliahui (Campoy, 1982);
S. corallicola Verrill, 1900;
S. lutea (Hartmann-Schröder, 1960); and
S. hyalina Grube, 1863. The species
S. garciai and
S. beneliahui are also new to the Caribbean and Gulf of Mexico areas. Several species from Bermuda and New England described by Verrill (1875; 1900) are revised.
