Paratanaoidean tanaidaceans (Crustacea: Peracarida) from littoral and shallow sublittoral habitats in New Zealand, with descriptions of three new genera and seven new species

Abstract

Three new genera and seven new species of paratanaoidean tanaidaceans are described from a variety of littoral and shallow sublittoral habitats around New Zealand, from the Snares Islands to Northland. These include a new leptocheliid genus, Parakonarus, closely allied to Konarus Bamber, and three paratanaids: two species of Paratanais Dana and a new genus, Atemtanais, which appears to show characters intermediate between Metatanais Shiino and Paratanais. The remaining three taxa belong either to the Tanaellidae (a new species of Araphura Bird & Holdich) or are of incertae sedis family status: Kanikipa n. gen. and a new species of Tanaopsis G.O. Sars.This study has almost doubled the known, published records of shallow-water tanaidomorphan species in New Zealand and all of the species are likely to be recorded more widely than the records here imply.
