ResumoThe geographic distributions and systematics of the Pieridae of the Andean highlands and Patagonia, Argentine Republic, are reviewed.Previously unpublished records based on twelve years' field work by the author and collections in Argentina, the United States, the United Kingdom, etc. are provided to clarify zoogeographic and systematic problems in this fauna.Tatochila blanchardii is reduced to a subspecies of T. autodice .The taxa T. arctodice, macrodice , sterodice, vanvolxemii and fueguensis all become subspecies of the widespread polytypic species T. mercedis.The possibility that Hypsochila wagenknechti and H. galactodice are conspecific is discussed.Records of putative galactodice from the puna of Jujuy are presented.The taxonomic history of Phulia nymphula in Argentina is clarified, and its range extended south to western Neuquen.Precise localities are given for the first time for the Chilean taxa Eroessa chiliensis and Mathania leucothea in Argentine Patagonia.Colias flaveola is* reported for the first time in Argentina.Colias mendozina, rediscovered in the highlands of Mendoza, is treated as a full species.Zoogeographic relations among the puna , the pampean ranges (Cumbres Calchaqufes -Sierra de Aconquija), the main cordillera , the Cordon del Viento, and Patagonia are clarified by the Pierid data.Previous work has overemphasized the distinctness of the Fuegian fauna, whose only important Pierid endemic is the possibly-extinct Colias ponteni.Subspeciation in most genera is probably of Quaternary origin, but speciation and certainly the origin of endemic genera or speciesgroups antedates the Pleistocene.The existing Pierid fauna represents the current stage in a long and complex process involving dispersal, vicariance, and evolution, the outlines of which are only beginning to emerge.Current distributions reflect both contemporary ecological phenomena and the long-term sequelae of past faunal movements in response to geoclimatic change.Resumen.La fauna de mariposas Pieridae de los sectores altoandinos y patagonico-fueguinos de la Republica Argentina fue analizada del punto de vista zoogeografico -historico, utilizando muestreos basados en 12 anos de colecta por el autor y los registros confiables de diversos museos y colecciones en dicho pais, Estados Unidos y Inglaterra, entre otros.La Tatochila blanchardii por razones de intergradacion espontanea ya se halla subespecie de T. autodice.Las taxa T. arctodice , macrodice , sterodice , vanvolxemii y fueguensis cambian en subespecies de la especie politipica muy ampliamente difundida T. mercedis.La ocurrencia de fenotipos muy parecidos a la Hypsochila
