Trachelomonas bituricensis var. lotharingia M.L. Poucques 1952, a morphologically interesting, rare euglenoid new to the algal flora of the Czech Republic

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.
