A new species of Pentaceration (Paramunnidae, Isopoda, Crustacea) from the Otago region of Aotearoa New Zealand

A new paramunnid species, Pentaceration forkandbrewer sp. nov., is described from Otago, Aotearoa New Zealand (Otago region). The majority of specimens examined were collected during a “Ports of Otago” survey carried out by the National Institute of Water and Atmospheric Research Ltd., Christchurch. Pentaceration forkandbrewer sp. nov. can be identified by the following characters: by the lack of dorsal protuberances, the reduced mid-head spine and the flattened, and calcified pereon with serrated margins. All the pereonites end in a point and are reasonably broad. Pentaceration forkandbrewer sp. nov. is most similar to the Australian species P. serrata and the Argentinian species P. pleonarietis . The new species is described, and an adapted key to the Pentaceration species of Aotearoa New Zealand is provided. LSIDurn lsid:zoobank.org:pub:138FAF76-3721-408F-AE39-C3F88F295E38.
