Abstract
This report describes the discovery of the rare euglenoid taxon Trachelomonas bituricensis var. lotharingia in a small mesotrophic pond in the Czech Republic. Only limited data are available on the distribution of this taxon as same as for typical variety of Trachelomonas bituricensis, even though this taxon is morphologically very well defined. I provide a brief discussion of the taxonomic validity of this taxon based only on morphological features, which are characteristic for the taxonomy of the genus Trachelomonas. This finding is completely new for the algal flora of the Czech Republic. This report provides new information about the worldwide distribution of this taxon and its ecology.
Highlights
Floristics studies have had a long tradition in the Czech Republic beginning in the second half of the 19th century, when several works about alga flora in this country were published
The algal flora of the Ďáblík pond is dominated by dinophytes (Peridinium spp.), together with desmids and metaphytic communities of Spirogyra spp. steril., as well as diatoms
The most interesting finding is the discovery of Trachelomonas bituricensis var. lotharingia, a newly recorded variety of algal flora in the Czech Republic
Summary
Floristics studies have had a long tradition in the Czech Republic beginning in the second half of the 19th century, when several works about alga flora in this country were published. Since the publication of pioneering works by Kirchner (1878) and Copyright Josef Juráň. The current knowledge about algal diversity in this region was summarised by Poulíčková et al (2004). All of these reports describe floristic studies examining the prevalence of all groups of algae in our state. Little is known about several of these groups and their distribution, e.g., diatoms, dinophytes and euglenoids
