Citation: Chrysoculter Nakayama, Yoshida, Noel, Kawachi & Inouye in Nakayama et al. 2005
Rank: Genus

Notes & discussion: Arguably a junior synonym of Navisolenia - Nakayama et al. (2005) do not discuss Navisolenia so may have overlooked it when creating the genus Chrysoculter

Catalog entries: Chrysoculter

Original description: Cells solitary, mostly asymmetric knife-shaped, 10–16 μm long, 3–6 μm wide. Two equal to subequal flagella, 14–26 μm, inserted at the cell apex. Haptonema 4–10 μm, noncoiling. Cells covered by two types of scales. Scales of the inner layer elliptical, 0.35 × 0.18 μm, with a narrow inflexed rim, and a radial pattern. Scales of the outer layer rhomboidal, 1.1 × 0.6 μm, with upright rim (50–80 nm), two projections, and a radial pattern. Rhomboidal scales do not overlap. Two pale yellow chloroplasts, lateral and parietal, are displaced horizontally, each with an immersed pyrenoid. The flagellar transitional region with a terminal transitional plate.
