Evolutionarily conservative host associations have been tempered by horizontal transfer and lineage duplication among closely related species.Independent and asynchronistic diversification of pollinating fig wasps is best explained by a combination of both sympatric and allopatric models of speciation.BACKGROUND: Symbiotic relationships have contributed to major evolutionary innovations, the maintenance of fundamental ecosystem functions, and the generation and maintenance of biodiversity.

RESULTS: Here, we use molecular methods to investigate cryptic diversity in the pollinating wasps of a widespread Australian fig species.

In this investigation, lineage delimitation and codiversification tests are used to generate and discuss hypotheses elucidating on pollinating fig wasp associations with fig wasp species are able to reproduce on multiple, but closely related host fig species.

Tree reconciliation tests indicate significant codiversification as well as significant incongruence between fig wasp and The findings demonstrate more relaxed pollinating fig wasp host specificity than previously appreciated.

Our study offers a striking example of extreme deviation from reciprocal partner specificity over the full geographical range of a fig-wasp system.

The interaction between insects and plants takes myriad forms in the generation of spectacular diversity.
