Some adaptations to endoparasitism in 20 species and 2 subspecies of euglenoid parasitic flagellates ihabiting gut of fresh water Copepoda have been studied. The trophozoites, dividing and flagellate forms have been examined by means of morphometric, morphological and cytochemical methods at light and electron microscope level. The developmental cycle, specificity and ecological conditions were analysed for establishing adaptative features. Three groups of species can be distinguished according to degree of their adaptations into parasitic way of life.

The results of the internal transcribed spacer (ITS2) of extrachromosomal rDNA and the chloroplast SSU rDNA sequence analysis presented here confirmed elevated genetic polymorphism revealed earlier by RFLP and RAPD for seven clones of the cosmopolitan species - Euglena agilis Carter. High diversity among these clonal strains was not reflected by morphological criteria, with the exception of the only one character - the ability of the cell in its non-motile dividing states (palmella) to produce mucus and form a slimy envelope. Evolutionary adaptation as formation of slimy envelope may be attributed to different survival strategy of the species by which it adapts to life in a highly variable environment.

One new Heteronema cf. distigmoides Christen and three rare taxa of H. acus (Ehrenberg) Stein, H. spirale KLEBS and H. nebulosum (Dujardin) Klebs were reported for the Polish flora. All of them were found in the mesotrophic Lake Piaseczno and in a small village pond in Kaniwola, in 2002. Both water reservoirs are situated on the Łęczna-Włodawa Lakeland (Eastern Poland). The above mentioned species are new to the flora of the Łęczna-Włodawa Lakeland, probably because of insufficient research, which was carried out on euglenophytes in this area previously. All the presented species are described thoroughly and illustrated in this paper.
