Resumen:
A revision of pliomerid trilobites from the San Juan Formation, Argentine Precordillera is carried out. It includes a new diagnosis for the genus Benedettia Toro and Monaldi, which is further included within the Subfamily Cybelopsinae Fortey. Besides, Encrinurus? niquivilensis Harrington and Leanza and Benedettia huaquensisToro and Monaldi are regarded as synonyms. Two new species: B. margaritae(Early Arenig) and Pliomerina sanjuanina (Early Llanvirn) are recognized. The latter is clearly distinguished among the pangondwanic species of the trilobite Pliomerina Chugaeva by its unusual pygidium.
