Baesemann (1973) erected the genus Aethotaxis to accommodate morphologically distinctive conodont elements from the Pennsylvanian (Missourian) of northeastern Kansas. By chance we have recently discovered that the name is preoccupied by a notothenioid perciform fish Aethotaxis DeWitt, 1962. Thus, in accordance with Article 60 of the International Code of Zoological Nomenclature (1999), we propose the name Ubinates nomen novum as a replacement for Aethotaxis Baesemann, 1973, not Aethotaxis DeWitt, 1962. Ubinates derives from the Latin ubi, meaning where (interrogative), and nates, meaning rump; this refers to the fact that it is not known which, if any, of the elements presently assigned to species of Ubinates occupied the posterior positions in the apparatus. The type species of Ubinates is U. advena by original designation (Baesemann, 1973).
