Five phyllodocidacean families (Alciopidae, Lopadorrhynchidae, Pontodoridae, Tomopteridae, and Typhloscolecidae) and two flabelligerid families (Flotidae and Poeobiidae) are dominated by transparent species (Uschakov, 1972; Glasby et al., 2000).
Polychaetes of the Suborder Phyllodociformia of the Polar Basin and the Northwestern Part of the Pacific: Families Phyllodocidae, Alciopidae, Tomopteridae, Typhloscoleicidae, and Lacydoniidae.
The Italian expeditions made on board the Liguria (1903-1905) included sites in western Mexico; as part of these cruises, Rosa (1907, 1908) described species of the planktonic families Tomopteridae and Alciopidae
. From 1923 to 1938, the Department of Tropical Research of the New York Zoological Society made several expeditions on board the Templeton Crocker and Zaca & Treadwell (1931, 1937, 1941, 1942) identified the polychaetes collected from these research cruises, including pelagic species.
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).
These include the work of Apstein (1891), who studied the Alciopidae deposited in the Natural History Museum in Hamburg and described several new species for Chile.
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. The following section presents the species identified, the number of examined specimens, and their geographic distribution (Table 1, Fig.
