形態描述
本屬物種的前上頜骨是圓的而不是尖的。雌獸有育幼袋，而且其乳頭在腹部排成對稱的兩排 [2]。除T. macrurus以外，其餘物種皆以其尾部儲存脂肪[3]，儘管可能這並不適7於所有同屬物種[4]。

化石物種
Fossils belonging to the genus date back to the 中新世, with the oldest specimens being found in the Cerro Azul Formation of 阿根廷 and the Honda Group of 哥倫比亞.[8] Genetic studies indicate that the genus may have originated around 14 million years ago.[9]
