Taxonomy:
Original description: Diagnosis: With characters of class and genus. Solitary, slender tadpole-shaped cells with a tail, 40–55 mm long and 8–12 mm wide. Rounded cells, 20–25 mm long and 13–18 mm wide. Two equal heterodynamic flagella with knob scales, 30–40 mm long. The hapto- nema 18–22 mm long, non-coiling. Cells covered with layers of extrusome-like bodies termed pot-shaped scales (PSS), the mature encapsulated form in peripheral cytoplasm 0.3 mm wide and 0.5 mm long, and the released PSS 0.35 mm wide and 0.45 mm long subtended by a raised portion of the cell membrane. Four golden-brown chloroplasts with a projected pyrenoid. A striated, fibrous, rhizoplast-like structure connects the nucleus and posterior end of the cell.
