Abstract. A new miospore genus Ductilispora is described to accommodate simple acamerate miospores, which have a distal ornament of folds like muri or thickenings. Five new species of trilete spores are defined: D. circularis sp. nov., D . longitudinalis sp. nov., D. corrugatus sp. nov., Verrucosisporites cortaderensis sp. nov., Dibolisporites malimanensis sp. nov. and Indotriradites variabilis sp. nov. The specimens have been recovered from the Malimán and the Cortaderas Formations (Early Carboniferous), in La Cortadera creek, San Juan province, Argentina.

Key words. Palynology. Cortaderas Formation. Malimán Formation. Lower Carboniferous. San Juan. Argentina.
