Taxonomy

The type species of Helaletes, H. nanus, is known from Bridgerian-age fossils in the western US.[1] Desmatotherium mongoliensis was previously referred to Helaletes, but Bai et al. (2017) found it distantly related to the H. nanus type species, while excluding the nominal species H. medius Qiu, 1987 from Helaletidae.[2]
