Resumen:
Eighty-one terrestrial species of spores and po 24 llen grains together with algae and fungi remains were recovered from the shallow lacustrine successions of the La Veteada Formation at the Chaschuil river section 27º43’50.5”S/68º01’17.0”W, Sierra de Narváez, Catamarca province, Famatina Range which are herein described and/or illustrated. This palynoflora is composed dominantly by a diverse association of taeniate pollen group (68%) and bisaccate (no-taeniate) pollen grains (24%) with less significant proportions of spores. The studied La Veteada palynoflora is referred to the upper part of the LW (Lueckisporites-Weylandites) Biozone, thus a Middle Permian (Guadalupian) age is established based on the presence mainly of Corisaccites alutas Venkatachala and Kar, Lueckisporites angoulensis Jardiné, L. nyakapandensis Hart, L. stenotaensis Menéndez, L. virkkiae (Potonié and Klaus) Clarke, Lunatisporites variesectus Archangelsky and Gamerro, Staurosaccites cordubensis Archangelsky and Gamerro, Striatoabieites anaverrucosus Archangelsky and Gamerro, Vittatina corrugada Marques-Toigo, V. costabilis Wilson, V. subsaccata Samoilovich, Convolutispora archangelskyi Playford and Dino, Striomonosaccites cicatricosus Archangelsky and Gamerro. The following species are recorded for the first time in argentinian Permian strata: Grebespora concentrica Jansonius, Alisporites parvus de Jersey, A. rioclarensis Menéndez, Falcisporites nuthallensis Clarke, F. stabilis Balme, Klausipollenites schaubergeri (Potonié and Klaus) Jansonius, K. staplinii Jansonius, Lueckisporites balmei (Tiwari and Vijaya) comb. nov., L. singhii Balme, Striatopodocarpites gondwanensis (Lakhanpal, Sah and Dube) Hart, Tornopollenites toreutos Morgan, Vittatina minima Jansonius, V. vittifera (Luber and Waltz) Samoilovich, Laevigatosporites flexus Segroves, Verrucosisporites surangei Tiwari and Banerji, Kendosporites sp., Minutosaccus sp., Protodiploxypinus sp., Vitreisporites signatus Palynology of the La Veteada Formation, Famatina, Permian Gutierrez, P.R. et al. 3 Leschik, Vitreisporites sp. cf. V. microsaccus de Jersey, and 48 Brazilea sp. cf. B. helbyi Foster.
