Analysis of some historically unfamiliar Canadian mayflies (Ephemeroptera)
Bibliographic record
Abstract
Abstract Twelve historically unfamiliar Ephemeroptera species described from Canada over 65 years ago were studied. Diagnostic characters are given that validateAcerpenna akataleptos(McDunnough) (Baetidae), whereas certain larval specimens of the genusAcerpennaWaltz and McCafferty cannot yet be associated with any species.Cinygmula confusa(McDunnough, 1924),syn.nov., (Heptageniidae) is shown to be a junior synonym ofCinygmula par(Eaton, 1885), andSerratella serratoides(McDunnough, 1931),syn.nov., (Ephemerellidae) is shown to be a junior synonym ofSerratella molita(McDunnough, 1930). New distribution records are given forIronodes flavipennisTraver (Heptageniidae),Cinygmula gartrelliMcDunnough,Heptagenia adaequataMcDunnough (Heptageniidae), andSiphlonurus autumnalisMcDunnough (Siphlonuridae), including the first substantiated records for the latter three from the United States. A first larval description ofS.autumnalisis provided.Ephemerella fraterculaMcDunnough (Ephemerellidae) is apparently rare, but its previously doubtful North Carolina record is confirmed. All larvae previously reported asNeoephemera bicolorMcDunnough (Neoephemeridae) cannot be placed to any nominal species.Parameletus croesus(McDunnough) (Siphlonuridae),Plauditus rubrolateralis(McDunnough) (Baetidae), andRhithrogena gaspeensisMcDunnough (Heptageniidae) are distinctive species but are known from few records.
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.
