“…However, it may be that they have a relatively high susceptibility to passive dispersal. Bell (1979) argued that Rhysodini beetles were amenable to passive dispersal in floating logs because both adults and larvae live inside dead wood. In the present study, Mecodema and Geodorcus beetles similarly have their larval stage within decaying logs, and Talitropsis and Celatoblatta also often have their daytime roosts in logs.…”

AimThe aim was to use mitochondrial DNA sequence data to test between vicariance and oversea dispersal explanations for the origin of the Chatham Islands biota.Location New Zealand and the Chatham Islands, separated by c . 800 km in the south-west Pacific Ocean.Methods DNA sequences from the mitochondrial gene cytochrome oxidase I (COI) were obtained from four genera of relatively large and flightless insects (Coleoptera-Geodorcus , Mecodema ; Orthoptera-Talitropsis ; Blattoidea -Celatoblatta ). These were used to test alternative hypotheses for the origin of the Chatham taxa.Results Phylogenetic analysis revealed the Chatham taxa in each genus to be monophyletic. Genetic distances exhibited by these genera, between taxa found on the Chatham Islands and mainland New Zealand were relatively low (11.2, 2.8, 3.0 and 4.9%, respectively). Main conclusionsEven allowing for variation in molecular evolutionary rates, these genetic distances indicate phylogenetic separation of New Zealand and Chatham insect lineages in the Pliocene (2-6 Ma). Such dates are more than one order of magnitude too recent to be explained by vicariant (tectonic) processes. Oversea dispersal from New Zealand to the Chatham Islands is implicated and this conclusion is in keeping with the taxonomy of the endemic avifauna, flora and fossil molluscan fauna.

“…The species are gregarious, and up to 50 individuals have been found in a single log. Al-though most species are winged, there are no published flight records, and it is believed that if they fly at all, it is only as a means to reach decayed areas in the upper branches of trees; dispersal by human transport of wood, or by rafting logs seems feasible (Bell, 1979). Only three species of rhysodines occur other than marginally on the Pacific Plate, all in the Eastern Caroline Islands.…”

NUMBER 367 exception: eastern Pacific taxa (for instance, the fish family Girellidae) that reach their western distributional limits at Easter Island, are not considered to be Pacific Plate taxa. Some Pacific Plate taxa that have their western distributional limits along the western margin of the Philippine Plate, usually the northern portion of that margin, are considered to be Pacific Plate restricted.
