Here, we attempt to elucidate the historical biogeography and the main triggers of taxonomic diversification within a group of ants. We find evidence that faunal interchange between Asia and Australia, via Wallacea, was an old zoogeographic event, occurring at least 20?15 Ma. Moreover, early cladogenesis events of extant New Guinean species most likely occurred along the northern part of the island. Dispersal to the Fiji Basin happened during the early and middle Miocene, in agreement with the subaerial Vitiaz Arc hypothesis. Finally, two diversification models were the most probable scenarios for the evolution of the group, the first one suggesting a one-process model with overall increasing speciation at about 6 Ma, and the second model favouring a rate shift in a clade consisting of geographically expanding taxa which had a shift in habitat preference. Altogether, ancient dispersal conduits were important for the colonization of Pacific archipelagos, although the rapid orogenesis in New Guinea, and possibly a subsequent ecological shift, triggered the taxonomic diversification of these insects.} }
