Morpho-anatomical and molecular reassessments of Rhodymenia prostrata (Rhodymeniaceae, Rhodophyta) from Japan support the recognition of Halopeltis tanakae nom. nov.
Bibliographic record
Abstract
We collected the deep-water species Rhodymenia prostrata (Rhodymeniaceae, Rhodophyta), for the first time in nearly 50 years, from the type locality off Mageshima Island, Japan. Our combined rbcL, cox1 and 28S rDNA analyses suggested that R. prostrata belongs in the genus Halopeltis but is distinct from all other Halopeltis species. However, the binomial Halopeltis prostrata already exists and hence a new epithet was required. Consequently, we propose the new name Halopeltis tanakae for R. prostrata based on morpho-anatomical and molecular analyses. The occurrence of small intercalating cells in H. tanakae is congruent with the generic concept of Halopeltis. Halopeltis tanakae is characterized by a procumbent thallus, crispate blades, cystocarps lacking basal constrictions, cystocarps primarily on blade margins, and mucilaginous strands in cystocarp cavities. Halopeltis tanakae is the second representative of the genus to be reported from the northwestern Pacific.

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.
