We design a neotype for Panochthus tuberculatus (Owen), given that the holotype is missing. A diagnosis and detailed description of the neotype is provided. Glyptodon tuberculatus is the type species of Panochthus Burmeister, one of the genera of giant Pleistocene glyptodonts. P. tuberculatus is recorded in the Bonaerean (late middle Pleistocene) and Lujanian (thus far only for the late Pleistocene lapse of this age) of Argentina, Uruguay, Brazil, Paraguay and, with doubts, Bolivia. Firstly, the species was recognized on the basis of two fragments of dorsal armor; this type material (two syntypes) must be considered as lost, given that it has not been found in the collections of British Museum Natural History, where it was deposited. It is essential that material assigned to P. tuberculatus be made available, to establish the validity of each of the 19 species referred to this genus. The selected material is the complete specimen MLP 16-29, from the Bonaerean of Tapalqué (Buenos Aires Province, Argentina). The specimen of P. tuberculatus available, to establish the validity of each of the 19 species referred to this genus.

The selected material is the complete specimen MLP 16-29, from the Bonaerean of Tapalqué (Buenos Aires Province, Argentina). The specimen of P. tuberculatus the Bonaerean (late middle Pleistocene) and Lujanian (thus far only for the late Pleistocene lapse of this age) of Argentina, Uruguay, Brazil, Paraguay and, with doubts, Bolivia. Firstly, the species was recognized on the basis of two fragments of dorsal armor; this type material (two syntypes) must be considered as lost, given that it has not been found in the collections of British Museum Natural History, where it was deposited. It is essential that material assigned to P. tuberculatus be made available, to establish the validity of each of the 19 species referred to this genus.

The selected material is the complete specimen MLP 16-29, from the Bonaerean of Tapalqué (Buenos Aires Province, Argentina). The specimen of P. tuberculatus We design a neotype for Panochthus tuberculatus (Owen), given that the holotype is missing. A diagnosis and detailed description of the neotype is provided. Glyptodon tuberculatus is the type species of Panochthus Burmeister, one of the genera of giant Pleistocene glyptodonts. P. tuberculatus is recorded in the Bonaerean (late middle Pleistocene) and Lujanian (thus far only for the late Pleistocene lapse of this age) of Argentina, Uruguay, Brazil, Paraguay and, with doubts, Bolivia.
