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

Abstract

During the Antarctic Polarstern cruises ANT XIX/3 (ANDEEP-I), XIX/5 (LAMPOS), and XXI/2 (BENDEX) new material of symbiotic copepods associated with polynoid polychaetes was collected. Here the authors present results for the highly modified family Herpyllobiidae Hansen, 1892. New records of Herpyllobius antarcticus Vanhöffen, 1913 and Herpyllobius polarsterni López-González, Bresciani and Conradi, 2000 are provided from the eastern Weddell Sea and Bouvet Island respectively. A new species of the genus Eurysilenium Sars, 1870, E. australis, is described from specimens collected at the eastern Weddell Sea. A new genus, Gottoniella gen. nov., is proposed to include two species, G. antarctica sp. nov. and G. andeepi sp. nov., described from material collected from the Weddell Sea and Scotia Arc.
