Echinochara Peck, 1957 is a poorly known charophyte genus from the Upper Jurassic and Lower Cretaceous of the United States and Europe. Its fossil record is currently limited to two species, Echinochara spinosa Peck, 1957 and Echinochara peckii (Mädler, 1952) nov. comb. Grambast, 1956 emend. Schudack, 1993, which have obscure phylogenetic relationships. A third species of this genus, Echinochara triplicata nov. sp., is described here from the Lower Albian of Jebel Koumine (Central Tunisia) and is hypothesized to derive from the Barremian-Aptian morphotypes of Echinochara peckii. The new species represents the first record of the genus in Africa and its more recent record worldwide. It occurs along with the clavatoraceans: Clavator harrisii zavialensis and Atopochara trivolvis trivolvis and provides an additional tool for the biostratigraphic characterization of non-marine Albian of Europe and North Africa.
