Mindarinae(Insecta: Aphididae)has specific association with Abies,Picea,Keteleeria conifers(including Christmas tree species),disjunct distribution patterns at global and regional scales,as well as reliable fossil records,which make this group a good system to investigate important hypotheses in biogeography and ecology.Based on global sampling and molecular data from mitochondrial,nuclear and Buchnera(primary endosymbiont of aphids)genomes,with integration of biological and fossil data,we reconstructed the phylogenetic framework of Mindarinae,estimated divergence times for major clades,and investigated key issues such as the evolution of disjunct distribution patterns and species diversification.Our major findings include: 1)several cryptic species have been revealed; 2)Mindarus keteleerifoliae in southwest mountains in China occupied the most basal position among all extant Mindarinae species; 3)a species complex in North America resulted from rapid radiation; 4)the disjunct distribution patterns have been jointly determined by relatively old and recent geological events; 5)host plant specialization and geographical factors have effected species differentiation in Mindarinae.
