ABSTRACT Aim The archipelago of Aotearoa displays both high biodiversity and a dynamic geologic history, shaped by constantly shifting coastlines the dramatic effects glacial cycling on forest cover across islands. This geographic history has important implications for evolution dispersal‐limited forest‐dwelling arthropods, such as Opiliones, which can help us reconstruct key past biogeographic events. In this study, we shed light evolutionary triaenonychid genus Algidia Hogg, 1920 . Location Aotearoa|New Zealand. Time Period Late Cretaceous to present‐day, with particular focus events in Oligocene onwards. Major Taxa Studied , Triaenonychidae, Arachnida. Methods We utilise an integrative phylobiogeographic approach, incorporating target enrichment sequence capture ultraconserved elements, divergence dating, species delimitation ecological niche modeling. Results Our genomic data conjunction dating find evidence structure influence multiple natural Aotearoa, including origination continuation Alpine Fault, marine transgression during cycles glaciation orogeny that characterised Pliocene Pleistocene results recover 10 putative species, four are undescribed. Paleoclimate modelling reflects changes Aotearoa's coastline potentially underpin modern distributions land bridges place current straits Raukawa Moana|Cook Strait Te Ara‐a‐Kiwa|Foveaux Strait. Main Conclusions phylogeny indicates consistent northwards expansion, earliest diverging clade, A. homerica located Rakiura southern Waipounamu, subsequently clades moving steadily their distributions. Diversification predates Marine Transgression, lending support now well‐established hypothesis was not fully submerged Oligocene. Fault seems be feature explaining cladogenesis populations, found Moana. However, other phenomena, glaciation, or continental shifting, also explanatory factors Aotearoa.
