Resumen:
Prepoplanops boleadorensis, a new genus and species of Planopinae (Xenarthra, Tardigrada), is described herein. The new
taxon is based on a nearly complete specimen recovered from the Cerro Boleadoras Formation (Miocene, Río Zeballos
Group), in northwestern Santa Cruz Province, Argentina. The shape and length of the predentary region of the skull and
the length of the diastema of Prepoplanops boleadorensis differ from those present in the species of Planops. The posterolateral
opening of the mandibular canal and the position of the posterior margin of the mandibular symphysis differ from
those of species of Prepotherium. In addition, Prepoplanops boleadorensis differs from Planops martini in the size of the
humeral tuberosities, the development of the deltoid crest, the position of the distal margin of the humeral trochlea, the
shape and position of the olecranon, the development of the femoral epicondyles, and the shape of the medial margins of
the patellar trochlea and medial condyle. On the other hand, it differs from Prepotherium potens in the shape of the medial
margin of the medial condyle. The recognition of Prepoplanops boleadorensis increases the diversity of Planopinae for
the Miocene of Patagonia, Argentina.
