Revision of the millipede genus Apheloria Chamberlin, 1921 (Polydesmida, Xystodesmidae, Apheloriini)

We revise the millipede genus Apheloria Chamberlin, 1921a colorful and often encountered group of millipedes in eastern North America. With molecular phylogenetics, we estimate the evolutionary history of the genus, and use it in combination with morphology to understand species diversity. We describe a new species, Apheloria uwharrie sp. nov. from North and South Carolina, synonymize Apheloria tigana Chamberlin, 1939 syn. nov. with Apheloria virginiensis (Drury, 1770), and remove Apheloria luminosa (Kenyon, 1893) syn. nov. from the genus and place it in synonymy with Pleuroloma flavipes Rafinesque, 1820. Currently there are six species of Apheloria: Apheloria corrugata (Wood, 1864) stat. nov.; Apheloria montana (Bollman, 1887); Apheloria polychroma Marek, Means & Hennen, 2018; Apheloria uwharrie sp. nov.; Apheloria virginiensis (Drury, 1770); and Apheloria whiteheadi (Shelley, 1986).
