Resumen:
Well preserved Mississippian palynological assemblages have been obtained from the Cortaderas Formation in the Río Blanco Basin,  northwestern Argentina.  The geological setting and stratigraphic provenance of the samples is provided. In this first part, fifty-two species are described from a total of seventy-eight species of spores recognized. Five  new species are proposed:  Verrucosisporites incompositus sp. nov., Verrucosisporites perbrevis sp. nov., Anapiculatisporites exiguus sp. nov., Anapiculatisporites expolitus sp. nov. and Dibolisporites insolitus sp. nov. Previous worldwide geographic and stratigraphic records of taxa are detailed.
