“…In the early years of diatom exploration in the Antarctic region, several new species have been described (West & West 1911;Carlson 1913). Most studies published subsequently were limited to the aquatic diatoms found in recent and subfossil lake sediments on the various Antarctic locations (Schmidt et al 1990;Fukushima et al 1994;Sabbe et al 2003) 2002) list all records of Muelleria. In spite of the high number of papers analysed in their review, only a few reported the presence of species of Muelleria (or species now so transferred).…”

During a survey of the terrestrial diatom flora of some sub-Antarctic islands in the southern Indian and Atlantic Oceans and of the Antarctic continent, more than 15 taxa belonging to the genus Muelleria were observed. Nine of these taxa are described as new species using light and scanning electron microscopy. Comments are made on their systematic position and how they are distinguished from other species in the genus. Additionally, two previously unrecognized taxa within the genus were discovered in samples from South Africa. One of these, Muelleria taylorii Van de Vijver & Cocquyt sp. nov., is new to science; the other, Muelleria vandermerwei (Cholnoky) Van de Vijver & Cocquyt nov. comb., had been included in the genus Diploneis. The large number of new Muelleria taxa on the (sub)-Antarctic locations is not surprising. Species in Muelleria occur rarely in collections; in many habitats, it is unusual to find more than 1-2 valves in any slide preparation. As a result, records are scarce. The practice of ''force-fitting'' (shoehorning) specimens into descriptions from common taxonomic keys (and species drift) results in European species, such as M. gibbula and M. linearis, being applied to Antarctic forms in ecological studies. Finally, the typical terrestrial habitats of soils, mosses and ephemeral water bodies of most of these taxa have been poorly studied in the past.

“…Several specimens of Fragilaria vaucheriae var. perminuta (Grunow) KO-Bayashi as reported by Fukushima et al (1994) from the Antarctic King George Island, show some affinities but are narrower (mostly 3.5 pm vs. 3.9-5.2 pm) and have a more elongated, linearlanceolate to lanceolate outline with convex margins whereas U. colcae presents more parallel, straight margins.…”
