  • This paper concerns the description of palynomorphs recovered from subsurface Early Carboniferousstrata of the SM-4 well located in the Llanos Orientales Basin, Colombia. Thirty-two species of spores arerecognized 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 withprevious records in the Viséan and Tournaisian of Western Europe and Western Gondwana.
