The geologically‐complex Indo–Australian–Melanesian archipelago (IAMA) hosts extraordinarily high levels of species richness and endemism has long served as a natural laboratory for studying biogeography evolution. Nonetheless, its geological history the provenance evolution biodiversity remain poorly understood. Here, we provide scenario IAMA informed by time‐calibrated molecular phylogeny 1006 Trigonopterus weevils – an exceptionally diverse radiation regionally‐endemic flightless beetles. Moreover, performed statistical biogeographic analysis examined timing patterns in accumulation lineages residing priori‐defined geographic units comprising IAMA. We estimate that originated Australia during early Paleogene. Subsequent rapid diversification area present‐day Papuan Peninsula suggests presence proto‐Papuan islands middle Eocene; New Guinea North Coast Ranges were colonized late Eocene, followed Highlands Bird's Head Peninsula. inferred terrestrial habitat Moluccas Sulawesi Oligocene subsequent colonization Sundaland Lesser Sunda Islands. Caledonia Samoa from Peninsula, their faunas also diverged Oligocene. These biota‐informed time estimates are compatible with data region shed new light on paleogeography, even where evidence been lost to erosion. Beetle thus appears have closely tracked IAMA, revealing uniquely well‐resolved view regional biogeography.
