Caninella Kukhtinov, 2015, a new genus of Upper Permian non-marine ostracods, was described in 2015 (Kukhtinov and Voronkova, 2015) as part of the superfamily Suchonelloidea Mishina, 1972. V.K. Golubev and M.A. Naumcheva (Borissiak Paleontological Institute, Russian Academy of Sciences) drew my attention to an earlier instance of use of this name (Gorskii, 1938) in the description of a new genus of Carboniferous corals. In accordance with Art. 60.3 ICZN (International …, 1999; Mezhdunarodnyi …, 2000) the genus name Caninella Kukhtinov, 2015 should be replaced due to homonymy. I suggest to replace the preoccupied name by a new genus name, Nadteia nom. nov. The name is derived from the Nadtei River on the Kanin Peninsula, which runs near the locality where the type species Nadteia spizharskii (Kashevarova, 1961) was found.
