Nymphalidae　is　the　most　diverse　butterfly　family　worldwide,　with　more　than　6000　species,　whereas　the　mitogenomic　data　of　nymphalid　species,　especially　the　subfamily　Danainae,　is　still　lacking　for　more　comprehensive　systematic　studies.　To　this　contribution,　the　complete　mitogenome　of　Danaus　genutia　(Lepidoptera:　Nymphalidae:　Danainae)　was　determined　via　sequencing　and　annotating.　The　mitogenome　in　total　consists　of　15,255　base　pairs　(bp),　containing　13　protein-coding　genes,　22　transfer　RNAs,　2　ribosomal　RNAs,　and　a　440-bp　noncoding　A+T-rich　region.　Furthermore,　phylogeny　of　the　subfamily　Danainae　was　reconstructed　applying　maximum　likelihood　and　Bayesian　inference　on　the　basis　of　the　mitogenomic　data　sets.　Combined　with　our　analysis　and　previous　studies,　the　genus-level　phylogenetic　relationships　within　the　subfamily　Danainae　are　((Tirumala　+　Danaus)　+　((Idea　+　Euploea)　+　(Ideopsis　+　Parantica))).　This　study　offers　molecular　information　and　provides　a　new　perspective　for　phylogenetic　research　within　the　subfamily　Danainae.
