<i>Haramonas pauciplastida</i> sp. nov. (Raphidophyceae, Heterokontophyta) and phylogenetic analyses of <i>Haramonas</i> species using small subunit ribosomal RNA gene sequences
Bibliographic record
Abstract
SUMMARY A new species of the Raphidophyceae, Haramonas pauciplastida sp. nov. from Canada is described. The genus Haramonas has been described based on the type species Haramonas dimorpha and currently only two species are known. This new alga belongs to the genus because it possesses a tubular invagination at the posterior end of the cell, producing a large amount of mucilage and generating both motile and non‐motile phases in its life cycle. The chloroplast color of H. pauciplastida is yellowish green, and is similar to that of Haramonas viridis Horiguchi et Hoppenrath. However, this alga differs from the other species of the genus in that it possesses fewer chloroplasts, which are rarely overlapping. The ultrastructual study shows differences between these two species in the number of thylakoids in the lamella, the presence of a scattered pyrenoid matrix, and the position of the plastoglobuli. The phylogenetic analyses of the small subunit ribosomal RNA gene from the Haramonas species reveal that three species can be distinguished genetically from each other and they form a robust clade in the Raphidophyceae. This result supports the notion that the characteristic features of Haramonas are synapomorphies. This is the first report of molecular data from the Haramonas species.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
