Abstract:
The Diplazontinae (Hymenoptera: Ichneumonidae) from New Zealand is examined. Three new endemic species are described: Woldstedtius dundasius sp. nov.; W. gauldius sp. nov.; and W. titirangiensis sp. nov. These are the first Woldstedtius to be described from New Zealand, and are relatively widespread, often occurring at high altitudes. The only other known Diplazontinae occurring in New Zealand is the cosmopolitan Diplazon laetatorius (Fabricius), which is commonly found throughout the country.
