We then estimated zodariids' diversification timeline using alternative methods and inferred its key biogeographic processes at the continental scale through ancestral range estimation and biogeographical stochastic mapping. Our robust phylogeny supports Zodariidae's monophyly, sister relationship with Penestomidae, and the subfamily classification—with <i>Procydrela</i> transferred to a new subfamily. Surprisingly, zodariids originated and diversified from the end of the Early Cretaceous onwards, after Earth's major landmasses separated. Multiple range changes between realms were inferred, all via jump dispersal, and most originating in the Afrotropics. Most routes were taken only once, except for increased connectivity between the Afrotropics, Madagascar and the Indomalayan regions. Of 14 jump dispersal events with reliably inferred routes, 10 were trans-oceanic whereas 3 were trans-climatic. We conclude that trans-oceanic dispersal was pivotal in zodariids' global distribution and diversification, giving origin to ~60% of its biota, and that climatic niche conservatism has limited trans-climatic colonization between land-connected regions.

New Zealand comprises high phylogenetic diversity of Rhaphidophoridae throughout its mesic zone, with most species occurring above ground.

By dramatically increasing taxon sampling relative to past studies, we recovered the Australian fauna as rampantly polyphyletic, with the remaining Macropathinae nested among six distinct Australian lineages. Deep divergences between major clades imply additional Australian lineages remain undetected, either due to extinction or sampling bias, and have likely confounded past biogeographic signal. We inferred the radiation of Macropathinae began during the Lower Cretaceous prior to the fragmentation of Gondwana with a potential Pangaean origin for Rhaphidophoridae.

A previous morphology-based analysis placed the genera of Darnini into three groups that differ in pronotal shape, suggesting that the common ancestor of each group acquired a different defensive strategy, mimicking either bird droppings, thorns, or raindrops. To test this hypothesis, we compiled the most taxon- and character-rich dataset for Darnini and related groups to date, using anchored hybrid enrichment to obtain data for 492 genetic loci comprising &gt;133,855 nucleotide positions for a total of 51 taxa (31 Darnini species, 11 representatives of other tribes of Darninae and 9 taxa representing other subfamilies).
