  abstract = {{A}s a major abiotic factor, climate change is expected to profoundly alter biological communities. {O}n this basis, identifying how past temperature variations affected species diversification and distribution can help to predict the effects of the ongoing climate change. {I}n this study, we focused on the harvester ant genus {M}essor {F}orel, which is adapted to dry environments by specializing in a granivorous diet. {T}he phylogenomic analyses of 2524 ultraconserved-element loci obtained from 58 {M}essor species and subspecies support their monophyly. {P}hylogenetic relationships uncovered in this study enabled us to redefine historical taxonomic groups, providing a solid basis for future revisions that encompass the entire genus diversity. {M}olecular dating and biogeographical analyses indicate an emergence in the {I}rano-{I}ndian area approximately 20 million years ago. {O}ur results suggest a rapid geographical dispersal from their ancestral range towards the {W}estern {P}alaearctic, reaching {N}ortheastern {A}frica during the early {M}iocene. {W}e found a major diversification event during the mid-{M}iocene climatic optimum, from which we inferred the emergence of the common ancestor of all {M}essor groups. {T}heir diversification appears to be affected by temperature, suggesting a higher speciation rate during warmer periods. {T}his confirms that the ecological specialization of {M}essor makes them strongly dependent on thermal conditions. {O}ur results highlight the importance of abiotic factors on diversification processes, especially for highly specialized species that may exhibit predictable evolutionary responses to climate changes.},
