Abstract
Pteronarcys biloba Newman, 1838 http://lsid.speciesfile.org/urn:lsid: Plecoptera.speciesfile.org: TaxonName:470669 (Figs. 13–17) Remarks and Distribution. Previous descriptions of the larva of this species are adequate. The first description was provided by Smith (1917). Claassen (1931) later provided a more detailed description. This species can be reliably separated from other members of the genus based on the presence of the conspicuous abdominal projections on abdominal segments 1-8 (Figs. 13, 14), the lack of a prominent acute lateral projection on the mesothorax (Fig. 15), and the acute angle (APP> 55) of the anterior pronotal projection (Figs. 15, 17). The distribution of this species extends from Canadian Maritime Provinces south to Alabama (Nelson 2000). Material examined.

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.
