Mitonuclear discordance, the incongruence between mitochondrial DNA (mtDNA) and nuclear (nuDNA), is a well-documented phenomenon with various potential explanations. One emerging hypothesis, ghost introgression, refers to genetic contribution of an ancient, extinct or unsampled lineage can now be tested using modern genomic data demographic models. In this study, we investigated evolutionary history Odorrana swinhoana complex (Anura: Ranidae), which includes O. swinhoana, utsunomiyaorum unidentified population highly divergent mtDNA. While phylogeny suggested as basal lineage, from ddRADseq revealed it mixture most derived sequences combined ancient Demographic modelling further supported all models incorporating outperformed those without it. These findings suggest that eastward expansion western replaced leaving only its mtDNA fragments genome in hybrid population. Our results provide one first documented cases introgression amphibians highlight widespread process. This study also underscores risks relying solely on for phylogenetic reconstruction species delimitation.
