Final Epithet
Helenea stroggyla Varol, in prep.
Basionym
Helenea stroggyla Varol, in prep.
Etymology
From the Greek stroggylos, meaning “round”, referring to its rounded outline.
Description
Small (<6.0 µm), circular species of Helenea are characterised by a small central area spanned by a cross with bifurcated arm terminations, supporting a short distal process with a distinct square-shaped termination.
Optical Properties
Optical properties consistent with those of Helenea, but its elongation direction cannot be determined.
Remarks
Helenea stroggyla is distinguished from Helenea conus by its smaller size (<6.0 µm) and by a relatively narrower central area relative to the width of the pelaga.
