Distribution of Iospilidae (Annelida) along the eastern Brazilian coast (from Bahia to Rio de Janeiro)
The family Iospilidae (Bergstrom, 1914), previously named Iospilinae, was considered by Ushakov (1972) as a subfamily of Phyllodocidae.
The aim here is to report on the distribution of species from the family Iospilidae, along the eastern Brazilian coast, describe their morphology, and relate their distribution to the environmental variables of the area.
uniformis, representing 94% of Iospilidae abundance in CIII and 100% in CIV.
Of the 83 families of known polychaetes (Rouse & Pleijel, 2001), only the Tomopteridae, Alciopidae, Lopadorhynchidae, Iospilidae, Typhloscolecidae, and Pontodoridae are exclusively pelagic (Fauchald, 1977; Stop-Bowitz,1981).
A total of eight species of planktonic polychaetes were determined; seven of these belong to the families Tomopteridae, Iospilidae, Lopadorhynchidae, Typhloscolecidae and one undetermined species belongs to the family Alciopidae.
Therefore, the results of this study increased the records of pelagic polychaetes and added species from the families Iospilidae and Typhloscolecidae.
