Halamphora primus (Bacillariophyta): a new diatom species from the Gulf of California, Mexico
Bibliographic record
Abstract
A new diatom species, Halamphora primus sp. nov. is here proposed, and described based on comparison of morphological traits. This new taxon has semi-lanceolate valves, strongly dorsiventral. Its ventral margin goes from slightly concave in the mid part to lightly convex toward the eccentric parts. Unlike most species of Amphora sensu lato that have the raphe distal ends curved dorsally, in H. primus these are curved ventrally. A ledge is present on the dorsal side of raphe, and a short conopeum extends along the raphe sternum fading before reaching the apices. A dorsal fascia is absent. Specimens were collected along with a highly diverse taxocoenosis (S=281) from the skin of stonefish in the Gulf of California, Mexico. However, the scarceness of H. primus frustules in the sampled taxocoenosis strongly suggests that it is not an epizoic form of the stonefish.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
