Cyst‐theca relationship of a new dinoflagellate with a spiny round brown cyst,<i><scp>P</scp>rotoperidinium lewisiae</i>sp. nov., and its comparison to the cyst of<i><scp>O</scp>blea acanthocysta</i>
Bibliographic record
Abstract
Summary Round spiny brown cysts with apiculocavate processes were isolated from sediments of L ake S aroma, J apan, C hangle H arbor, E ast C hina S ea, C hina, J inzhou H arbor, B ohai S ea, C hina, and S an P edro H arbor, C alifornia, USA . Superficially similar round spiny brown cysts of the species, O blea acanthocysta were, for comparison, restudied through light microscopy and scanning electron microscopy ( SEM ) and by sequencing of small subunit ( SSU) and large subunit ( LSU) rDNA obtained through a single cyst from L ake S aroma. These morphological measurements and SEM observations showed that the new cysts can be discriminated from O . acanthocysta by the archeopyle, number of processes, shape of process bases and its apiculocavate processes . Based on LSU sequences, the most closely related species was P rotoperidinium monovelum , for which no cyst stage has been described so far. However, the thecal morphology of the specimens found in this study differed from P . monovelum in details of the sulcal plates and shape of apical pore and 2a plate. We therefore describe P rotoperidinium lewisiae sp. nov., which can be found in estuarine subtropical to temperate waters of the P acific O cean.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
