This article reviews current knowledge of wall morphogenesis in pennate diatoms in relation
to the way characters are defined and described for taxonomic and systematic analyses. It …

We review the literature on species flocks in diatoms. Past descriptions of species flocks in
diatoms are of few species and do not demonstrate monophyly of the taxa explicitly. The …

Light and scanning electron microscope observations are presented for Karthickia
verestigmata gen. et sp. nov. The taxon is described from Laos and Vietnam. This diatom …

The new genus Kurtkrammeria is erected to include 13 species assigned to Encyonopsis
that have (1) slit-like or crescent-shaped areolae aligned lengthwise along the apical …

For the first time, a giant diatom species of the genus Cymbella from Lake Baikal was
studied using molecular methods. Molecular and morphological investigations allowed to us …

During this investigation, sixteen species from the genus Gomphonema were found in a
shallow bay (near Oimur, Kabansky District) located on the eastern shore of Lake Baikal …

Species from the genus Oricymba are studied from freshwater ecosystems of Vietnam and
Laos. Three species were found in Vietnam, namely O. japonica, O. subovalis and O …

A total of eight species of the genus Humidophila (Bacillariophyceae) are reported from karst
regions of Guizhou Province, China. Of the eight species reported, only two have been …

Four new diatom species from the genus Cymbella Agardh are described on the basis of
light and scanning microscopy. These are Cymbella eunotioformis sp. nov., C …

Molecular data is provided firstly for the newly erected genus Qinia, and the phylogenetic
position of the genus Qinia within the Cymbellales is discussed. Despite the presence of …
