Scenedesmus and Desmodemus are two genera belonging to the Scenedesmaceae family. The present study sampled two genera of micro-algae in three ponds located at Mbanza-Ngungu, Kongo Central Province, DR Congo. In the study, 14 species (10 species of Scenesdemus and 4 species of Desmodemus) from the two genera were identified and described. They include Scenedesmus acuminatus (Lagerheim) Chodat, S. alternants Reinsh, S. armatus (Chodat) G. M. Smith, S. dimorphus (Turpin) Kuetzing, S. quadricauda (Turpin) Brebissonii, S. ecornis [Ehrenberg, Chodat, S. obliquus (Turpin)], Scenedesmus sp., Desmodesmus abundans (Kirchner) E. Hegewald, D. intermedius (Chodat) E. Hegewald, D. magnus (Meyen) Tsarenko and D. opoliensis (P.G. Richter) E. Hegewald. The diversity of these two genera species is greater in Kola pond and mostly in Voke.
