Resumen:
In the Pleistocene of South America three genera of Tardigrada Scelidotheriinae have been recognized as valid, Scelidotherium Owen, Valgipes Gervais, and Catonyx Lund. Recently, a fourth genus, Scelidodon Ameghino, has been considered of uncertain validity.In this contribution we carried out a restudy of the holotype of ?Scelidodon copei? (type species of the genus), including a comparison with other quaternary Scelidotheriinae. The evidence shows a remarkable morphological similarity between the holotype and juvenile specimens of Scelidotherium leptocephalum Owen, which in turn explains the small size mentioned by previous authors as a diagnostic feature.
