Two hundred and eight infrageneric taxa were identified, 90 of them are new records for the Catamarca province. The genera: Frankophila and Microcostatus and the species Achnanthes thermalis var. rumrichorum Lange-Bertalot; Amphora mira Krasske; Brachysira atacamae Hustedt; Frankophila similioides Lange-Bertalot & Rumrich; Gomphonema punae Lange-Bertalot & Rumrich; Haloroundia speciosa Diaz & Maidana; Luticola mollis Lange-Bertalot & Rumrich; Mastogloia atacamae Hustedt; Microcostatus andinus Lange-Bertalot & Rumrich; Navicula atacamana Patrick; Navicula parinacota Rumrich & Lange-Bertalot; Planothidium chilense (Hustedt) Lange-Bertalot; Staurosira pseudoconstruens (Marciniak) Lange-Bertalot; Surirella chilensis var constricta Hustedt y Surirella wetzellii Hustedt are new records for Argentina.
