摘要

•ddRAD dataset of the complex genus Thymallus (Salmonidae) was used for this study.•Nuclear and mitochondrial phylogenies show few but important incongruencies.•Rare cases of introgression are reported in two of the four contact zones.•Past introgression events are congruent with the hypothesis of Asian dispersal.•Combining markers helps uncover evolutionary histories in non-model organisms.
