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.
