The enigmatic beetle tribe Nototylini (Carabidae) is revised and a key to species is provided. Two species from South America are included in the genus. One species, Nototylus fryi (Schaum), is reviewed and a second, Nototylus balli Erwin & Kavanaugh, sp. nov., is described as new. Each species is known from a single specimen, neither of which is in good condition. The possible function of what appears to be a unique antennal grooming structure on the front femur is discussed.
