Resumen:
The long-nosed armadillos ofthe Dasypus genus are the richest andmore widespread extant xenarthra. In 1933, the prominent Argentineanmammalogist Jose V. Yepes studied specimens collected by Salvador Mazza and nameda new species: D. mazzai. Severalauthors interpreted that the holotype of the species was a juvenile of D. novemcinctus. In 1995, Vizcaínosupport the synonymy with D. novemcinctusbut accepted the existence of an endemic species of northwestern Argentina thatdedicated to Yepes (D. yepesi). The sequencingof the mitogenome and morphological studies have questioned the synonymy of thespecies with D. novemcinctus. In thiscontribution we reviewed the identity of the type material by sequencing a DNAfragment of 212 bp, product of the 16S ribosomal unit of Dasypodidae. Bothsamples of the holotype (bone and muscle) and of a specimen from the north ofSanta Fe province have a 100% similarity with the D. yepesi / D. sabanicolasequences available in the GenBank. These results indicate that the typespecimen of D. mazzai is neither a D. novemcinctus nor another species ofthe Dasypus genus previously named. Dasypus mazzai is revalidated and theeastern boundary in the Chaco region is confirmed. Field work is required toconfirm the conservation status and current distribution of this endemicmulita.
