Rediscovery of theOchromonastype speciesOchromonas triangulata(Chrysophyceae) from its type locality (Lake Veysove, Donetsk region, Ukraine)

:Ochromonas triangulata, the type species for a genus with over 125 taxa, was collected for only the second time, again from the type locality. Cell morphology, cell division, palmelloid stage and cyst structure generally agreed with the original description. Molecular phylogenetic analysis based on the 18S rRNA gene revealed 13 clades of Ochromonas-like flagellates as well as the clade represented by our O. triangulata strain and the nearly...
