Ancistrosyllis fioronii, a new species of Pilargidae from the North Sea, with a key and synoptic table of characters for all species of the genus Ancistrosyllis McIntosh 1879 (Annelida, Polychaeta, Pilargidae).
For three of these species, taxonomic adjustments have been made at the family level: according to Blake (1993), Pilargis mirasetis, initially included in the family Pilargidae, belongs to the genus Santelma, in the family Nautiliniellidae established in 1993 by Blake; Flabelligella macrochaeta (Flabelligeridae) is a member of the family Acrocirridae by Light (1978); and the serpulid Hydroides glandiferum is a type of the genus Olgaharmania by Rioja (1941b) within the Serpulidae.

Sigambra parva (Pilargidae) occurred almost exclusively in the mudflat, where it accounted for 30 % of the polychaetes, and at site III nearby (7 %).
Pseudexogone Augener 1922, previamente incluido en el grupo, no es un silido; pertenece a los Pilargidae. Se examinaron 814 ejemplares recolectados en el Caribe Mexicano, estos se distribuyen en tres generos, tres subgeneros y 13 especies que corresponden a: Brania (4), Exogone (4) y Sphaerosyllis (5); se incluye la descripcion de cinco nuevas especies: Brania russelli n.
