Border membrane 4.0–5.0µm (4.6 ± 0.3) in width. Diameter of denticulated ring 26.0 - 30.0µm (28.2 ± 1.7). Number of denticles about 26–29 (n = 16). Number of radial pins (mode) per denticle 10–12 (n = 16). Span of denticle 13.0–17.0µm (15.6 ± 1.7). Length of denticle 5.0–7.0µm (5.6 ± 1.3). Blade shape slender, 5.0–6.0µm (5.4 ± 0.5) in length. The anterior blade surface concave and forming an S-shape, not extending past Y+1 axis. Apex of blade absent. The posterior surface forming arch curve with deepest point of blade, and not parallel to anterior blade surface. Distal blade surface smooth and relatively straight, lower than tangent point. Apophysis of blade present but the posterior projection absent. Blade connection relatively broad. Central part well developed with rounded point fitting tightly into preceding denticle, just extending about half way to Y-1 axis. Shape of central part above X axis similar to the part below. Width of central part 2.0–3.0µm (2.3 ± 0.6). Ray connection short but stumpy, inconspicuous and barely distinguishable from ray. Ray thin, smooth and needle-shaped, tapering gradually to sharp point and directed forward, tip of ray almost touching Y+1 axis. Ray apophysis not prominent and length of ray 5.0–8.0µm (6.6 ± 1.7). Ratio between denticle above and below X axis about one. Adoral ciliary spiral turns about 370º–390º around peristomial disc. Macronucleus U-shaped, and micronucleus spherical, situated in –Y1 position.</paragraph>
