A new species of Papilio from the eastern United States (Papilionidae)

A new species Papilio joanae is described. The male and female types, a mature larva, and the male genitalia are figured. The type locality is Warsaw, Missouri in forested areas. This multivoltine species differs from its nearest relatives Papilio polyxenes asterius Stoll, 1782 and Papilio bairdii Edwards, ( 1867 ) in wing pattern characteristics and differences in color and pattern of the larvae. The presently known range is restricted to forested areas in the Missouri Ozarks. The larvae feed on wild species of APIACEAE. The male and female types have been deposited in the American Museum of Natural History.
