- Abstract
Determine the phylogeny and dispersal patterns of the cicada genusKikihiain New Zealand and the origin of the Norfolk, Kermadec, and Chatham Island cicadas.New Zealand, Norfolk Island, Kermadec Islands and Chatham Island.DNA sequences from 16 species and four soon to be described species of cicadas from New Zealand and Norfolk Island (Australia) were examined. A total of 1401 base pairs were analysed from whole genome extraction of three mitochondrial genes (cytochrome oxidase subunit II, ATPase6 and ATPase8). These DNA sequences were aligned and analysed using standard likelihood approaches to phylogenetic analysis. Dates of divergences between clades were determined using a molecular clock based on Bayesian statistics.Most species in the genusKikihiadiverged between 3 and 5 million years ago (Ma) coincident with a period of rapid mountain building in New Zealand. Cicada species on the Kermadec and Norfolk Islands invaded recently from New Zealand and are closely related to the New Zealand North Island speciesKikihia cutora.Speciation in the genusKikihiawas likely due in large part to the appearance of new habitats associated with the rise of the Southern Alps, startingc.5 Ma. Dispersal ofKikihiaspecies within mainland New Zealand probably occurred gradually rather than through long-distance jumps. However, invasion of Norfolk, the Kermadecs and Chatham Islands had to have occurred through long-distance dispersal.
