Abstract:
For this study, we have examined the literature and the morphological diversity, as well as analyzed the nuclear SSU rDNA sequences of two very common and cosmopolitan species formerly known as Euglena deses Ehrenb. and Euglena intermedia (G. A. Klebs) F. Schmitz. Our studies have shown that there is evidence for distinguishing only one species (E. deses). Here, we define new diagnostic features for E. deses, namely, periplast ornamentation (the presence of small papillae-discovered for the first time in this species) and the lateral location of the anterior canal opening, from which the flagellum emerges. We also designate the epitype and emend the diagnosis for E. deses.
