摘要：

The carpus and metacarpus of a Pleistocene Proterotheriidae tentatively attributed to Neolicaphrium recens Frenguelli from Cordoba Province, central Argentina, are described herein. The manus is tridactyl, with metacarpals II and IV well developed as in "Proterotherium" and Diadiaphorus; in this respect Neolicaphrium is primitive relative to the monodactyl manus of the Miocene Thoatherium. Nevertheless, the squaring of the carpus and the slender metacarpal III resemble the pattern of Thoatherium and Prothoatherium better than that of "Proterotherium", Diadiaphorus and Megadolodus, thus suggesting a slightly greater degree of specialization in comparison with the last three genera.
