    Morphological observations and emended description of<i>Amphora micrometra</i>from the Bolivian Altiplano, South America
    (Taylor & Francis, 2011) Éva Ács; Luc Éctor; Keve T. Kiss; Csaba Cserháti; Eduardo A. Morales; Zlatko Levkov
    Abstract A population of Amphora micrometra Giffen, collected in September 2002 from different habitats in Laguna Blanca in the Bolivian Altiplano, South America, has been examined using light transmission and scanning electron microscopy. The original description of this species is incomplete and insufficient to characterize the taxon in the light of the newly collected ultrastructural data. The holotype of A. micrometra was examined during the present study and compared to Bolivian specimens. An emended diagnosis of A. micrometra using all available information is provided. A taxonomic discussion based on available literature and the ecology of the taxon is also presented herein.

    Staurosira grigorszkyi nom. nov. (Bacillariophyceae) an araphid diatom from Lake Balaton, Hungary, with notes on Fragilaria hungarica Pantocsek
    (Schweizerbart science publishers, 2009) Éva Ács; Eduardo A. Morales; Keve T. Kiss; Beáta Bolla; Andjelka Plenković-Moraj; Mária N. Reskóné
    Abstract: Epilithon and epiphyton samples collected from Lake Balaton (Hungary) in 2006 and 2007 contained, as dominant, specimens similar to those described in 1902 by Pantocsek as Fragilaria hungarica. Since Pantocsek had previously used the name F. hungarica in 1892 for a fossil taxon from Demend (Slovakia), the Lake Balaton specimens required a new name. Additionally, information collected during this study, using light (LM) and scanning electron microscopy (SEM), supports the transfer of the specimens from Lake Balaton to the genus Staurosira Ehrenberg. The nomenclatural consequences from Pantocsek’s dual use of the name F. hungarica, are solved herein by the proposal of the new name Staurosira grigorszkyi nom. nov.
