Localities of H. cresphontes and H. rumiko specimens with available DNA barcode information. Color of circles corresponds to species: H. cresphontes - blue (based on 112 DNA COI barcode sequences, 103 obtained in this work); H. rumiko - red (based on 183 barcodes, 146 obtained in this work), split red/blue circles mark localities where both H. cresphontes and H. rumiko were recorded. Type localities for taxa with available names are indicated with a corresponding name followed by “TL”. We treat Papilio cresphontes var. maxwelli Franck, 1919 & Papilio cresphontes pennsylvanicus F. Chermock & R. Chermock, 1945 as junior subjective synonyms of H. cresphontes. Countries and states (for USA and Mexico) with records are labeled.
