Abstract
Examination of collections from waters around New Zealand resulted in significant findings of six species of Metacrangon Zarenkov, Citation1965, a crangonid shrimp genus well represented in the North Pacific: M. knoxi (Yaldwyn, Citation1960); M. richardsoni (Yaldwyn, Citation1960); M. hikurangi sp. nov.; M. haona sp. nov.; M. rau sp. nov.; and M. teina sp. nov. The present material includes the second record of the two previously described species since their original descriptions. The four new species are all closely related to M. knoxi, suggesting a monophyletic origin of these five species. Differentiating characters among the four new species and M. knoxi are discussed in detail. All six species are known only from New Zealand waters, and they are probably endemic to the area.
