  abstract = {{N}ew {C}aledonia is a megadiverse tropical island in the southwest {P}acific, however, inhabited by only one species of amphibian, {L}itoria aurea ({H}ylidae). {W}e used both molecular ({CO}1 and {ND}4 gene sequencing) and morphometric data to explore its geographical origin and timing of colonisation. {W}e tested whether this species arrived through transoceanic dispersal before human arrival in the island, or recently through anthropogenic introduction. {W}e found a weak phylogeographical structure within this species, and lower haplotype diversity in {N}ew {Z}ealand, {N}ew {C}aledonia and {W}allis compared to {A}ustralia. {N}o significant genetic differentiation was found between pairs of populations in {N}ew {C}aledonia and {W}allis, or between pairs of population from these two islands. {W}e observed a high level of morphometric differentiation between {A}ustralian and island populations, and a low level of morphometric differentiation between island populations. {O}ur results support an {A}ustralian origin for insular frogs. {T}he possibility of a trans-marine dispersal from {A}ustralia to {N}ew {C}aledonia and/or {W}allis in-between the {E}ocene and the {P}leistocene cannot be favoured, given the low level of genetic differentiation. {O}ur results are consistent with a recent human introduction, most likely during {E}uropean times. {O}ur data support the historical absence of amphibians in the old island {N}ew {C}aledonia, and is consistent with the new biogeographical paradigm that this island was totally re-colonized after emergence in {E}ocene. {M}ore studies are necessary to explain the success of this frog in oceanic islands, where it is widespread and abundant, compared to {A}ustralia, where it is declining.},
