New variety peridinium gatunense nygaard var. kinnereta Krachmalny (Dinophyta) from Lake Kinneret (Israel)

The diagnosis and pictures of the new variety Peridinium gatunense var. kinnereta Krachmalny var. nov. from Lake Kinneret (Israel) are given. This variety differs from the type in morphology and position of the apical plates and sutures (1' - asymmetrical, large, upper part is shifted to the left side of the body; 3' - wedge, elongated; 4' - almost rectangular, its length more than twice exceeds the width; sutures between 4' and 7", 4' and 1' plates form an almost straight line; suture between 1' and 2' is considerably smaller than the suture between 1' and 4' plates, consequently the shape of the plate 1' is close to triangular). Specimens of P. gatunense var. kinnereta were compared with samples from other regions where this species is recorded: fresh reservoirs of North, Central and South Americas, Central Africa, Europe, and Tasmania.
