Diatomeas (Bacillariophyceae) en humedales de altura de la Provincia de Catamarca (Argentina). III Maidana, Nora I. Seeligmann, Claudia T. Diatomeas humedales Andes Catamarca Argentina. Diatoms (Bacillariophyceae) in high-altitude wetlands of Catamarca Province (Argentina). III. Within the framework of the research on high mountain wetlands conducted since 1998, we have already studied 24 waterbodies in this province. In order to expand our knowledge on diatom flora in these high mountain environments, in this opportunity we analyze another 12 wetlands located between 25º34'05"27º39'23" S, over 3000 m asl. Diatoms were found in all samples, except in Laguna Azul, with almost white water by the large amount of suspended solids. In relation to salinity, waters were from fresh to hypersaline, with a predominance of sodium and chloride ions. We identify, excluding Fragilariaceae, 42 genera with 123 infrageneric taxa, 29 of which are new records for the province of Catamarca and, 4 for Argentina and we propose a new species (Anomoeoneis punae sp nov.). The majority of the species belong to Navicula (17), Nitzschia (13), Halamphora (12), Surirella (8), and Anomoeoneis (7). There were not found species common to all samples and only six appeared in more than 50% of the waterbodies. A high percentage (54%) of rare species, found only in one or two of the samples, was obtained. En el marco de la investigación de humedales de alta montaña que realizamos desde 1998, hemos estudiado ya 24 cuerpos de agua de esta provincia. Con el objetivo de ampliar los conocimientos de la flora diatomológica en ambientes de alta montaña, en esta oportunidad analizamos otros 12 humedales ubicados entre los 25°34’05’’-27°39’23’’ S, a más de 3000 m snm. Encontramos diatomeas en todas las muestras, excepto en la de la laguna Azul, que es casi blanca por la gran cantidad de sólidos en suspensión. En relación a la salinidad, las aguas fueron desde dulces hasta hipersalinas, con predominio de los iones sodio y cloruro. Identificamos, excluyendo las Fragilariaceae, 42 géneros con 123 taxones infragenéricos, 29 de los cuales son nuevos registros para la provincia de Catamarca, 4 para Argentina y proponemos una nueva especie (Anomoeoneis punae sp nov.). La mayoría de las especies pertenecen a los géneros Navicula (17), Nitzschia (13), Halamphora (12), Surirella (8) y Anomoeoneis (7). No se encontraron especies comunes a todas las muestras y sólo seis tuvieron una frecuencia de ocurrencia mayor al 50 %. Se obtuvieron altos porcentajes (54 %) de especies raras, halladas solo en una o dos de las muestras.
