the HRZ suggests a more recent genetic connection with subsequent geographic isolation across the TRZ / HRZ boundary. Both Clades 4 and 5 appear to be geographic isolates within the TRZ. This is consistent with climatic data suggesting long-term geographic isolation as the primary driver for the huge diversity of endemic species and populations found in the Stirling Ranges (Clade 5) (

The distributions of clades 2 and 4 also fall within different IBRA subregions of the Esperance Plains; the Fitzgerald (Clade 2) and Recherche (Clade 4). Both regions comprise subdued coastal sandplains on the coast, but differ in environmental aspects such as rainfall and geological substrate (
