Abstract

Past climatic and geological events significantly influenced the diversity and distribution of modern taxa. Here I aimed to understand what processes shaped species diversity in Western Australia (WA) over the past 12 MY. Focusing on trapdoor spiders (Mygalomorphae: Nemesiidae: Aname) I found various lineages that experienced multiple distributional shifts between arid and mesic bioregions. Within Aname I identified one species, Aname mellosa, which exhibited contrasting phylogenetic patterns between mitochondrial and nuclear genes. In-depth analyses using RADseq data identified two genetically divergent lineages within this species, with independent biogeographic origins, hinting at the complex evolutionary history followed by this group.
