The complete mitochondrial genomes of two Iphiclides species, namely I. podalirius and I. podalirinus, were sequenced, assembled, and reported in this article. Both genomes comprise 37 genes, with 13 protein-coding genes, 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. The gene orders and alignments agree with the reported mitogenomes of Leptocircini butterflies, while the start codon for the COX1 gene in I. podalirinus is CGA instead of the commonly seen ATN type. Codon preference shows that methionine and tryptophan are the poorest, while arginine, leucine, and serine are the richest. Phylogenetic analysis using Bayesian Inference shows both Iphiclides species are sister to the genus Lamproptera and are basal to all remaining Leptocircini species. The Kimura 2-parameter (K2P) distances of I. podalirinus from I. podalirius exceed 5%, demonstrating its solid species status. The K2P distance between the North African feisthamelii and podalirius exceeds 2%, indicating the reasonable elevation of I. feisthamelii to the full specific level as its type locality is Algeria. Future research is required to tackle the relationship between the Iberian feisthamelii and podalirius using more evidence.
