Abstract
Using mitochondrial COI-5P as a barcode marker, the red algal species previously identified as Digenea simplex in Bermuda is shown to be distinct from this species found in the Adriatic (type locality) and Mediterranean Seas, as well as other tropical locations worldwide. This finding led to a comparative study of the morphology of Bermuda specimens and D. simplex from the type locality, as well as other congeners. Our data show the Bermuda specimens to be morphologically, as well as genetically, distinct from D. simplex necessitating the description of D. arenahauriens sp. nov. for plants found in the islands and a single collection from the Caribbean Sea. It represents the first species partitioned from the “pantropical” D. simplex and we present genetic evidence of additional undescribed isolates in the species complex requiring further study.

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 it
