SEELIGMANN, Claudia; MAIDANA, Nora I.  y  MORALES, Marcelo. Diatoms (Bacillariophyceae) from high altitude wetlands of Jujuy province-Argentina. Bol. Soc. Argent. Bot. [online]. 2008, vol.43, n.1-2, pp.1-17. ISSN 1851-2372.

A diatomological analysis of thirteen high altitude wetlands, between 3500-4683 m a. s. l. of Jujuy Province (Argentina) was performed. Fifty one genera and one hundred and fifty seven infrageneric taxa, excluding Navicula sensu stricto species, were identified; three of them are new records for Argentina and 43 are new for Jujuy Province. A new combination is proposed: Craticula cuspidata var. gracilis. The finding of Cylindrotheca gracilis (Bréb.) Grunow is important, since it has not been previously mentioned for this kind of environments. Amphora veneta Kützing var. veneta was recorded in more than 90 % of the studied waterbodies while Nitzschia hungarica Grunow, Craticula cuspidata (Kützing) D. G. Mann var cuspidata and Luticola cohnii (Hilse) Lange-Bertalot were found in more than 60% of the samples.
