Staines CL and Weisman DM. 2001. The Species of Xanthonia Baly 1863 (Coleoptera: Chrysomelidae: Eumolpinae) in North America East of the Mississippi River. Proceedings of the Entomological Society of Washington. 103(1):157-183
ABSTRACT: The genus Xanthonia Baly is revised for eastern North America, with nine species. The species X. decemnotata (Say) and X. villosula (Melsheimer) are redescribed; S. stevensi Baly is removed from synonymy with X. villosula. Neotypes are designated for X. decemnotata, X. stevensi, and X. villosula. The new species S. angulata from Maryland to Kansas, S. furcata from Illinois and Missouri, X. intermedia from Alabama and Iowa, X. monticola from the mountains of New York and North Carolina, X. serrata from Massachusetts to Louisiana, and X. striata from Massachusetts to Texas are described and a key to the species is presented.
