The flatid planthopper, Metcalfa pruinosa (Hemiptera: Flatidae), which is an invasive species, widespread in Korea. We sequenced a fragment of the COI from 536 individuals collected mainly Korea and European countries combined these sequence data with public data, totaling 830 worldwide. identification one shared haplotype only between USA, presence this North-West region Korea, highest diversity suggested that another point entry addition to South-East region, presumed sole Furthermore, it involves M. originating USA. In effort find further variable regions mitochondrial genome, provided substantially increased variability compared COI. FST estimation, PCoA, BAPS analysis, using concatenated sequences newly detected infer expansion pattern indicates main highway, running obliquely regions, appears be responsible for current population genetic structure facilitating gene flow through highway traffic.
