Abstract

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. Resumen. ALGUNAS ESPORAS TRILETES DE ESTRATOS DEL CARBONÍFERO INFERIOR DE LA CUENCA DE RÍO BLANCO, OESTE DE ARGENTINA. En este trabajo se propone el género Ductilispora nov. gen. para miosporas acavadas, con escultura distal compuesta por pliegues similares a muros o engrosamientos. También se designan cinco nuevas especies: D. circularis sp. nov., D. longitudinalis sp. nov., D. corrugatus sp. nov., Verrucosisporites cortaderensis sp. nov., Dibolisporites malimanensis sp. nov., e Indotriradites variabilis sp.nov. Estas formas provienen de secuencias del Carbonífero Inferior (Formaciones Malimán y Cortaderas) que afloran en la quebrada de La Cortadera, al este de la provincia de San Juan, República Argentina.
