Anatheta Casey 1910 (type species Sableta (Anatheta) planulicollis Casey 1910) is confirmed to be a valid genus separate from Sableta Casey 1910 (type species Sableta (s. str.) infulata Casey 1910). Two valid species are recognized in Anatheta: A. planulicollis (Casey 1910) (transferred from Sableta), and A. surrufa (Casey 1911) (transferred from Metaxya Mulsant et Rey 1873). Metaxya erudita Casey 1911 is recognized as a junior synonym of Anatheta planulicollis (Casey 1910). Sableta (Anatheta) curata Casey 1910 is not a member of Anatheta and is close to Acrotona Thomson 1859. Canastota Casey 1910 (type species Sableta (Canastota) canadensis Casey 1910), believed by Seevers (1978) to be very similar to Anatheta, is placed in synonymy with Silusida Casey 1906; Sableta (Canastota) canadensis Casey 1910 is placed in synonymy with Silusida marginella (Casey 1906). Lectotypes are designated for Metaxya erudita Casey 1911, Metaxya surrufa Casey 1911, Bolitochara marginella Casey 1893 and Sableta canadensis Casey 1910. Redescriptions and illustrations of distinctive structural features are provided for distinguishing Anatheta from other aleocharine genera and for recognizing the two valid species in the genus.
