Journal of the Royal Society of New Zealand abstractsThe beetle (Coleoptera) fauna of the Antipodes Islands, with comments on the impact of mice; and an annotated checklist of the insect and arachnid faunaJ. W. M. Marris**Entomology Research Museum, Soil, Plant and Ecological Sciences Division, P O Box 84, Lincoln University, Canterbury, New Zealand; email marris@lincoln.ac.nz.The beetle fauna of the Antipodes Islands is described, and the origin, distribution and biogeography of the fauna discussed. Collections from Bollons Island in the Antipodes group are reported for the first time. A total of 25 species is recorded from the islands, including seven new species and nine new distribution records from the islands. Nine species (36%) are endemic to the Antipodes Islands, 14 (56%) species are indigenous, one species is introduced and one is of unknown origin. The fauna is most closely allied to the Auckland and Campbell Islands but has links with other subantarctic islands of the New Zealand subregion and the New Zealand mainland. Comparison between the invertebrate faunas of Antipodes Island and mouse-free Bollons Island indicate that mice have had a major impact on both the abundance and faunal composition of the Antipodes Island invertebrates. An annotated checklist of the insects and arachnids of the Antipodes Islands is given. A total of 150 insect species and 20 arachnids is recorded. Nine species are new to science and 31 are newly recorded from the islands. Two new bird hosts of ectoparasitic insect species are recorded for New Zealand and two are recorded for the Antipodes Islands.Keywords insects; Coleoptera; arachnids; Antipodes Islands; endemism; biogeography; subantarctic fauna; mice
