The families Pilargidae and Hesionidae are usually found in macrofaunistic studies and are represented by a reasonable number of individuals. Nowadays, there is about 50 species described of pilargids. The number of genera can vary from 10 to 14, due to the monophyly of several and of the specialist interpretation. There are approximately 150 species of hesionids belonging to 20 genera. Preliminary results from samples of Biota/Fapesp indicate the presence of the following species of Hesionidae - Gyptis plurisetis Hilbig, 1992, Microphthalmus sp., Ophiodromus puggetensis (Johnson, 1901), Podarkeopsis cf. levisfuscina Perkins, 1984, Syllidia armata Quatrefages, 1865, and Pilargidae – Ancistrosyllis cf. carolinensis Gardiner, 1976, Ancistrosyllis jonesi Pettibone, 1966, Cabira incerta Webster, 1879, Litocorsa antennata Wolf, 1986, Loandalia tricuspis (Muller, 1858), Pilargis berkeleyae Monro, 1933, Pilargis maculata Hartman, 1947, Sigambra cf. wassi Pettibone, 1966, Sigambra grubei (Muller, 1858), Sigambra ocellata (Hartmann-Schroder, 1959), Sigambra tentaculata (Treadwell, 1941), and Synelmis albini (Langerhans, 1881). However, to confirm the names of these taxa is necessary to exam type material and also the participation of specialists in these families. This project has the aim of to exam the pilargids and hesionids from Biota/Fapesp - Bentos Marinho and Revizee/Score Sul - Bentos programs. The comparison of our material with holotypes and paratypes is a way to ratify the compromise assumed with the assessor (process number 02/04104-0). (AU)
