This paper concerns the description of palynomorphs recovered from subsurface Early Carboniferous strata of the SM-4 well located in the Llanos Orientales Basin, Colombia. Thirty-two species of spores are recognized within the palynoflora. A new species is proposed: Spelaeotriletes colombianus Dueñas and Césari sp. nov. The assemblages were referred to the Tournaisian-Viséan by the presence of distinctive spore species with previous records in the Viséan and Tournaisian of Western Europe and Western Gondwana.
