Brachoria is a genus of polydesmidan millipedes in the family Xystodesmidae inhabiting the Eastern United States. Also known as the Appalachian mimic millipedes, at least 30 species are known, with highest diversity in the Appalachian Mountains, especially the Cumberland Plateau and Ridge and Valley Province. Species of Brachoria are boldly patterned with yellow, orange, red, violet that contrasts with a black background, and in the Appalachians some species mimic species of Apheloria where they co-occur, a phenomenon known as Müllerian mimicry
