Abstract
Tribelos jucundum (Walker) Figs 47 A–E Diagnosis. Frontal apotome separated from S3 setae by straight suture (Fig. 47A); labrum and premandible as in Fig. 47B; SI seta plumose; pectin epipharyngis with three toothed platelets; antenna (Fig. 47C) 5-segmented, last three strongly reduced, LO large enveloping segment 3, blade twice as long as flagellum, AR 1.3; mandible (Fig. 47D) with 3 inner teeth, their combined length is greater than the distance from basal tooth to seta subdentalis, inner margin with a large appressed spine near the base; mentum (Fig. 47E) with 4 median teeth of which the middle pair is usually shorter, 6 lateral teeth, 1 st lateral is smaller than the 2 nd, and a line extends from the anteromedian tip of VM plate towards the outer median tooth but does not connect. Notes. This species is easily distinguished from other Tribelos by the long antennal blade. The larva generally agrees with the description by Grodhaus (1987). Ecology and habitat. The larvae of this species are found in shallow (0.5–4.5m) parts of lakes and streams on sandy substrates with muck and under weed beds (Grodhaus 1987). Sampling sites. Mississagi, Little White River, Arrowhead and Algonquin Provincial Parks. Also collected in streams in Muskoka and Parry Sound Districts. Nearctic distribution. Canada: British Columbia to New Brunswick, including Ontario. USA: Oregon to Oklahoma and Florida.
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.
