Haptolina,

Original description: Cells symmetrical, spherical to oval or conical, with two equal, homodynamic flagella. Haptonema slightly shorter, equal or longer than the flagella, and can be coiling or non-coiling. Haptonema and flagella inserted apically. Cells may have large organic spine scales. The flagellar apparatus may have a simple R1 flagellar root. Nucleotide sequences for the SSU and LSU rDNA distinct
