• Parnassius clodius nr baldur - Ken Davenport says only two sightings in Kern Co.
• Papilio eurymedon - Ken has an undescribed Coast Ranges segregate that is "more yellowish or cream colored."

Note: An important paper published in 2004* placed P. machaon, polyxenes, zelicaon, and indra in the subclade or subgenus Papilio within the genus Papilio; P. rutulus, eurymedon, and multicaudata were placed in subgenus Pterourus; cresphontes, the western populations of which are now recognized as species rumiko, was placed in subgenus Heraclides. Battus philenor remained in a different tribe altogether. Since then, evidence suggests these subgenuses (Papilio, Pterourus, and Heraclides) can be considered genus-level taxons. I tend to go back-and-forth between adopting new names and sticking to current ones when well-known butterflies are involved, as it can lead to confusion.
