“…The continental Australian faunas segregate into the wet Western Australian forests and the Eastern Australian region, which forms a continuous belt of diversity from New South Wales to the Wet Tropics. The third clade shows two instances of Tasmania/New Zealand vicariance [31]: one for Ooperipatellus, and another including a few Tasmanian species and the New Zealand endemic genus Peripatoides.…”

The current distributions of widespread groups of terrestrial animals and plants are supposedly the result of a mixture of either vicariance owing to continental split or more recent trans-oceanic dispersal. For organisms exhibiting a vicariant biogeographic pattern-achieving their current distribution by riding on the plates of former supercontinents-this view is largely inspired by the belief that Pangaea lacked geographical or ecological barriers, or that extinctions and dispersal would have erased any biogeographic signal since the early Mesozoic. We here present a time-calibrated molecular phylogeny of Onychophora (velvet worms), an ancient and exclusively terrestrial panarthropod group distributed throughout former Pangaean landmasses. Our data not only demonstrate that trans-oceanic dispersal does not need be invoked to explain contemporary distributions, but also reveal that the early diversification of the group pre-dates the break-up of Pangaea, maintaining regionalization even in landmasses that have remained contiguous throughout the history of the group. These results corroborate a growing body of evidence from palaeontology, palaeogeography and palaeoclimatic modelling depicting ancient biogeographic regionalization over the continuous landmass of Pangaea.

“…The New Zealand Onychophora has been studied in detail (Gleeson 1996;Trewick 1998Trewick , 1999Trewick , 2000Allwood et al 2010). Two independent genera are recognised in New Zealand, Peripatoides and Ooperipatellus, both of which find their sister clade in Tasmania (Ooperipatellus is a transTasman genus), or Tasmania and/or mainland Australia (Peripatoides) (Gleeson et al 1998;Allwood et al 2010). The presence of deep genetic structure within Peripatoides has been interpreted to indicate an ancient origin with local survival of populations through climate cycles (Goldberg et al 2008).…”

Abstract. Evaluating the hypothesis of New Zealand's total submersion during the Oligocene requires the strictest tests, including sound phylogenetic data and dating of phylogenies. Although New Zealand has been traditionally considered to host ancient biota that originated by vicariance after it separated from Australia~80 Mya, the ancient origins of its biota have been recently questioned, with some authors even suggesting that all current land organisms had to arrive to the islands after it re-emerged from the ocean 22 million years ago. Here we examine examples of short-range endemic soil-dwelling invertebrates and find compelling evidence that at least some of them are the result of old lineages that diversified in New Zealand before the hypothesised submersion event 22 million year ago. We conclude that New Zealand indeed has old lineages as well as recently diversified lineages and compare this situation with that of other more stable areas of the Neotropics.

“…Allozyme data revealed no close relatives among the limited number of New Zealand and Australian peripatus studied . A survey of Australasian Onychophora using mitochondrial DNA, that supported monophyly of the New Zealand Peripatoides, also included specimens from one location in Dunedin (Gleeson et al 1998).…”

“…At present, however, Dunedin peripatus have been represented in studies only by specimens from two sites (Caversham and Leith valleys), both of which are close to the city centre , Gleeson et al 1998. Before any interpretation of nationwide phylogeographic patterns can be made, a more complete understanding of local diversity and geographic range is required.…”

“…In a sense this is a reversal of the situation that arises from morphology-based analyses which, naturally, tend to underestimate biogenetic diversity (Avise 1994). In the study of Onychophora for instance, a group noted for their morphological conservatism, genetic methods have revealed extensive cryptic diversity , stimulated revision of morphology based taxonomy (Reid 1996) and provided insights into the origin of diversity within, and biogeography of, species (Hebert et al 1991;Gleeson et al 1998).…”

Onychophora tend to be morphologically conservative. Several studies using molecular techniques have revealed the existence of cryptic species and population structuring. The application of allozyme electrophoresis to New Zealand peripatus that were thought to belong to a single widespread species (Peripatoides novaezealandiae) has revealed several undetected species, including a taxon specific to Dunedin (southern South Island, New Zealand). However, almost nothing is known about the geographic range and variability of this species, nor indeed whether it comprises one or more cryptic taxa. I used analysis of cytochrome oxidase I mtDNA sequences to explore these aspects of peripatus found in the vicinity of Dunedin. Eighteen different haplotypes were detected in 47 individuals from 21 locations. The sequence of a 540 bp COI fragment contained 64 parsimony informative sites and nucleotide diversity of up to 11% among ingroup taxa. Phylogenetic analyses, and genetic distance by geographic distance correlation, indicated probable species-level divisions within the sample. Two principal groups with a boundary on the east coast of New Zealand near the mouth of the Taieri River can be defined, and these are denoted "Dunedin" and "Catlins" peripatus. There is a third, possibly distinct lineage at Piano Flat. A rearrangement of the mitochondrial genome, relating to the position of the tLEU rna gene, was detected in these and other New Zealand peripatus and may be present in all Onychophora. Z99006
