Systematics and evolution of the Australian Dacini (Diptera: Tephritidae)

Abstract

This thesis investigates the drivers of fruit fly speciation in Australia. Utilising genetic and fossil data, a dated phylogeny was produced and used to investigate trait evolution across the tribe. Morphological data was evaluated for its utility in phylogenetic reconstructions and found to have limited signal. Biogeographic analysis showed flies entered Australia from PNG, and into the Western Pacific from both PNG and Australia. Additionally, the study documented new fruit fly species, new distributions, and new lure records. The results help refine the taxonomy and systematics of the tribe and support future work in pest management.
