Euglenozoa occurring in Adzopé Reservoir, Côte D’Ivoire

The Euglenozoa flora of the Adzope Reservoir in Cote d'Ivoire was investigated from January to December 2005. The species composition of the assemblage was compiled, accompanied by illustrations. Forty-four taxa were identified in the temporal survey. Ten taxa (22.22%) are new for Cote d'Ivoire. The taxonomic structure presents 22.32% of the species common to the freshwater of West Africa, with most of the taxa (89.5%) found to be cosmopolitan. An endemic taxon, Trachelomonas pisciformis var. bicoronata Coute & Iltis (Euglenaceae), was observed. The assemblage was dominated by Trachelomonas Ehrenberg and Phacus Ehrenberg, which represented 47.72% and 29.54% of identified taxa, respectively. Two common species, Trachelomonas volvocina (Ehrenberg) Ehrenberg (Euglenaceae) and Trachelomonas volvocinopsis Svirenko (Euglenaceae), were also recorded. The highest species richness of Euglenophyceae in the Adzope Reservoir was in relation with nutrients (NO3- and PO43-) and organic matter.
