The northwest Pacific marginal seas are a primary center of phylogeographic and evolutionary research, because of their dynamic geographic history of falling and rising sea levels during the glaciations and interglaciations of the last one million years. Here we present new molecular and morphological data for geographic samples of the four-eyed sleeper (Bostrychus sinensis), which reinforce the evidence for secondary contact and hybridization between two phylogeographic lineages in the East China Sea. Specifically, we find that the secondary contact region is characterized by a low frequency of hybridization, where mitochondrial DNA introgression is relatively common, whereas F |
