Are there any Navicula species (Bacillariophyta) living exclusively in high altitude environments of Argentina? In order to analyze the geographical distribution of 28 species of the genus Navicula Bory sensu stricto, identified in high mountain wetlands in Argentina, we consulted the five available catalogs, publications not included in those works, and unpublished data collected in surveys conducted by our team. Information was gathered from more than 190 water bodies in Argentina, Bolivia, and Chile, from which maps were constructed using the DIVA-GIS software. These maps allowed us to visualize the distribution of species and relate them to the altitude of the sites where they were found. Only five taxa (18% of total identified species in high mountain wetlands) were found exclusively in high altitude water bodies in Argentina: Navicula atacamana, N. carvajaliana, N. parinacota, N. salinicola var. boliviana and N. phylleptosoma. Of these species, the only one that is not exclusively American is N. phylleptosoma, which would have a wide distribution. While there are numerous studies carried out on the subject of diatoms of Argentina, it is interesting to note the large area of the country that still remains to be surveyed. Future studies may modify the knowledge we now have regarding the distribution of species which is, apparently, restricted to high mountain environments. Con el objetivo de analizar la distribución geográfica de 28 especies del género Navicula Bory sensu stricto identificadas en humedales de alta montaña en Argentina, se consultaron cinco catálogos disponibles, publicaciones no incluidas en esas obras y datos recabados en relevamientos inéditos realizados por nuestro equipo de trabajo, considerando la nomenclatura actual y los sinónimos de cada especie. Se reunió información procedente de más de 190 cuerpos de agua de Argentina, Bolivia y Chile, a partir de la cual se construyeron mapas utilizando el software DIVA-GIS, que permitieron visualizar la distribución de las especies y relacionarla con la altura sobre el nivel del mar de los sitios donde fueron encontradas. Solo cinco especies (el 18 % del total de especies identificadas en los humedales de alta montaña) fueron halladas exclusivamente en cuerpos de agua de altura de Argentina: Navicula atacamana, N. carvajaliana, N. parinacota, N. salinicola var. boliviana y N. phylleptosoma. De estas especies, la única que no es exclusivamente americana es N. phylleptosoma, que tendría una amplia distribución. Si bien hay numerosos trabajos realizados sobre diatomeas de Argentina, es interesante notar la gran superficie del país que aun resta por relevar. Es posible que futuros estudios modifiquen el conocimiento que ahora tenemos sobre la distribución de las especies aparentemente restringidas a ambientes de altura.
