However, the interplay between abiotic and biotic factors driving the evolution and distribution of Indo-Pacific insects remains largely unexplored. We focus on the trap-jaw ant genus Odontomachus to elucidate the roles of paleogeography and ecology for the evolutionary success of insects in tropical and subtropical environments. The origin of Odontomachus ants (39?45 Ma) coincided with the warm climate of the early Cenozoic, and its ancestral widespread distribution in the Oriental and New World regions is in line with the Boreotropical para-tropical rainforests dominating the Northern Hemisphere. Long-distance dispersal from the New World along the Equatorial Pacific has significantly contributed to the extant ant diversity of the Indo-Pacific region. Trans-Pacific dispersal events in Odontomachus are reported for the mid-Miocene, Pliocene, and modern human-mediated spread. Biotic interactions and shifts in habitat preferences, as suggested by the original taxon cycle hypothesis, may have facilitated further geographical range expansion across distinct Melanesian ant lineages over the past 10 Ma. Overall, Indo-Pacific ants' diversity and distribution have likely been modulated by paleoenvironmental changes, including ancient climate and geographical modifications, as well as ecological interactions.} }
