New genus, three new species and new records of Herpyllobiidae Hansen, 1892 (Crustacea, Copepoda), parasites of polychaetes from Antarctica

The family Herpyllobiidae Hansen, 1892 is one of the most highly transformed families among the parasitic Copepoda, grouping a few genera of uncertain ordinal placement (see López-González and Bresciani, 2001), although the arrangement of 3 aesthetascs on the antennules of herpyllobiid copepodid stages provides evidence that the family belongs to the poecilostome copepods (Boxshall and Halsey, 2004). Three genera have been traditionally considered in this family: Herpyllobius Steenstrup and Lütken, 1861 (17 species), Eurysilenium Sars, 1870 (4 species), and the ill-defined Phallusiella LeighSharpe, 1926 (2 species). All herpyllobiids (except Herpyllobius hartmanae Lützen and Jones, 1976; see López-González and Bresciani, 2001: Table 1) parasitize polynoid polychaetes (Lützen, 1964).
