Biodiversity, Phylogeny, and Evolutionary Dynamics of Gall Midges on Japanese Beech Trees.

ABSTRACT: The Japanese Archipelago harbors unique beech flora (Fagus L.; Fagaceae), with a parapatric distribution of two endemic species, F. crenata and F. japonica, upon which a diverse array of 34 types of leaf galls induced by gall midges (Diptera: Cecidomyiidae) has been documented. The inducers of most of these galls remain undescribed, and their phylogenetic relationships with known taxa are still poorly understood. In this study, we collected 29 types of leaf galls from the two Japanese Fagus species, including 6 previously unreported types, and sequenced the cytochrome c oxidase subunit I mitochondrial gene of the inducers to infer maximum-likelihood and Bayesian time-calibrated phylogenies. Our phylogenetic analyses revealed that the Fagus-feeding
