•Stratigraphic comments. The material described here represents the first record of a Neosclerocalyptus species

•from the Vorohué Formation (Vorohuean Subage, late Pliocene). Remains of Auliscomys cf A. osvaldoreigi (MMP 5356) were collected from the infilling of an ancient vertebrate burrow situated at the same stratigraphic level where N. castellanosi was recovered. A. osvaldoreigi is a species restricted to the Ctenomys chapadmalalensis Biozone (Quintana 2002). Thus N. castellanosi sp. nov. cannot be more modern than Sanandresian Subage, according to the time averaged character of this bioconstruction. In this context, Kraglievich (1952) provided a litostratigraphic chart identifying those levels as Vorohuesian subage.
