| Abstract: | The subfamily Deltocephalinae is represented in New Zealand by 3 tribes, 9 genera, and 20 species, of which 3 genera and 13 species are new to science. All taxa are described, and keys are given for their separation. Three of the genera are endemic, 3 are Australian, 2 are Holarctic, and 1 is cosmopolitan. Nesoclutha and Macrosteles are recorded in New Zealand for the first time, and the presence of Deltocephalus is authenticated. Fourteen species are endemic, 4 are Australian, 1 is widespread in the Pacific area, and 1 is Holarctic. Nesoclutha pallida, Macrosteles fieberi, and Deltocephalus hospes are recorded in New Zealand for the first time. |
