Fragilariaceae (Bacillariophyta) in high altitude wetlands of Catamarca (Argentina)

Three high mountain wetlands were studied in the Catamarca Province, Argentina, as part of a larger study focusing on high mountain waterbodies in the Argentinian Andes. In this contribution we present species in the group of small Fragilariaceae found so far in: Laguna Diamante (hiperhaline), Lagun...

In this contribution we present species in the group of small Fragilariaceae found so far in: Laguna Diamante (hiperhaline), Laguna Salitre (fresh) and Laguna Negra (mesohaline). The species belong to the genera Staurosira, Staurosirella and Pseudostaurosira. Three species, Staurosirella galanensis, S. salitrensis and Pseudostaurosira ferrarioae are new to science, which are herein described, illustrated and compared to morphologically similar taxa. S. galanensis is smaller and more rhomboidal than the other cruciform species of the genus, while S. salitrensis is smaller and less silicified than closely related species. Pseudostaurosira ferrarioae is distinguished from similar taxa especially by its well developed apical pore fields. The other representatives of the family found in these sites were Staurosira binodis, which is a new record for the Catamarca Province, Pseudostaurosira altiplanensis, cited here for the first time for Argentina and P. aff. polonica. Se estudiaron tres humedales de alta montaña en la provincia de Catamarca, Argentina, como parte de un estudio más amplio que se enfoca en cuerpos de agua en los Andes argentinos. En esta contribución damos a conocer dentro del grupo de Fragilariaceae de pequeño tamaño, especies de los géneros Staurosira, Staurosirella y Pseudostaurosira halladas en las lagunas Diamante (hiperhalina) y Salitre (dulce) y en la vega de la laguna Negra (mesohalina). De las especies encontradas, Staurosirella galanensis, S. salitrensis y Pseudostaurosira ferrarioae son nuevas para la ciencia y fueron descritas, ilustradas y comparadas con taxones similares. S. galanensis es más pequeña y romboidal que otras especies cruciformes del género, mientras que S. salitrensis es de menor tamaño y menos silicificada que otras especies estrechamente relacionadas. Pseudostaurosira ferrarioae se distingue de especies afines especialmente por tener campos de poros apicales bien desarrollados. Los otros representantes de esta familia encontrados en el área de estudio fueron Staurosira binodis, especie que se menciona por primera vez para Catamarca, Pseudostaurosira altiplanensis, citada por primera vez para Argentina y P. aff. polonica.
