Tanaidacea (Crustacea: Peracarida) of the Kermadec Biodiscovery Expedition 2011

Six species of tanaidacean – one apseudomorphan (Paradoxapseudes floppae sp. nov.) and five tanaidomorphans (Zeuxo kermadecensis sp. nov., Tanais sp., Leptochelia acrolophus sp. nov., Metatanais progenitor sp. nov., and Aparatanais tetradonta sp. nov.) – are recorded from the Kermadec Islands (SW Pacific) that extend from Raoul Island in the North to L’Esperance Rock in the South. Five are considered to be new species but with close relatives in warm-temperate/tropical eastern Australia, Melanesia-Polynesia, or New Zealand. A new paratanaid subfamily, Metatanainae, is established from new morphological data and recording of the first dimorphic males of the genus Metatanais. Two genera, Metatanais and Tanais, are new records for the New Zealand marine fauna. Because of insufficient comparative evidence, no firm conclusions can be drawn about the predominant zoogeographic affinities, or origins, of the Kermadec Islands tanaidacean fauna, but it is likely that both warm-water and southern (i.e. New Zealand) sources are involved.
