Conservation status of Prodontria (Coleoptera: Scarabaeidae) species in New Zealand

Abstract

The genus Prodontria (Scarabaeidae: Melolonthinae), which comprises 16 described species, is an endemic southern New Zealand genus occupying lowland and coastal habitats, inter-montane basins and alpine environments. Many of the species have a limited distribution and face potential threats from habitat change and predation. The only species to be formally protected is P. lewisii Broun, commonly known as the Cromwell Chafer, which is now restricted to a 81-ha reserve in Central Otago. One undescribed lowland species might be extinct as a result of habitat modification. The current status of Prodontria species, the known distribution of species and potential threats are discussed.
