Selandriinae, a subfamily of family T enthredinidae ( H ymenoptera: S ymphyta), comprises multiple tribes, each of which has a relationship with specific plant group. The host specificity of the S elandriinae taxa provides a good model to examine the coevolution between hosts and insects. However, few phylogenetic studies for the S elandriinae obscure the evolutionary scenario with their host‐plants. The present study is a molecular phylogenetic analysis of 19 selandriine species based on mitochondrial genes ( 12 S : 461 sites, 16 S : 262sites and COI : 495 sites) and nuclear genes ( 18 S : 773 sites and 28 S : 495 sites). The results suggested three of six studied tribes are genetically isolated. Moreover, estimation of the time of molecular divergence showed that the S elandriinae clearly diverged at the same time as their host‐plants (monocots and ferns). These results suggested that the Selandriinae species might have codiversified with their hosts.
