Bibliographic record
Abstract
Crepidostomum opeongoensis Caira, 1985 (Trematoda: Allocreadiidae) is redescribed from fish hosts Hiodon alosoides and Hiodon tergisus in southern Manitoba. The redescription adds details regarding the surface morphology and reproductive structures of the parasite not described previously. These include the characteristic tegumental papillae around the oral opening, paired papillae on the ventral and dorsal surfaces of the body, and tegumental bosses on the dorsal surface of the forebody. Crepidostomum opeongoensis co-occurred with its hypothesized sister species. Crepidostomum illinoiense, in all host individuals harboring the former, and both species are characteristic of hiodontids. The association of C. opeongoensis with hiodontids and the absence of hiodontids in Lake Opeongo where C. opeongoensis was originally reported indicate that the Algonquin Park region may have had hiodontids in the past and that the life cycle may be completed at present without the original fish host.
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.
