Abstract
Key to species of Dufourea in eastern North America [All species except D. marginata have been recorded from Michigan.] 1. Both sexes: Pubescence of body very dark (Fig. 2); compound eyes diverging below (Fig. 1). Male: Metasomal sternum six with strong ventrally-directed keel (Fig. 2) (specialist on Campanula; alpine/boreal distribution) ............. D. maura (Cresson) —. Both sexes: Pubescence of body light in part (Fig. 3); compound eyes parallel or converging below. Male: Metasomal sternum six with apically-directed keel (Fig. 3) ........................................................................................................................... 2 2(1). Both sexes: Head longer than wide (Fig. 4) ............................................................. 3 —. Both sexes: Head wider than long (Fig. 5) ............................................................... 4 3(2). Female: Mouthparts (stipes, first labial palpomere) with abundant setae (Fig. 6); mesobasitarsus bowed posteriorly, width at midpoint distinctly greater than apex (Fig. 7). Male: Posterior margin of propodeal dorsum rugulose (Fig. 10); metatrochanter with ventral angle acute (Fig. 11); metasomal sternum six with oblique submedial swellings carinate (Fig. 12) (specialist on Pontederia) .............. .......................................................................................... D. novaeangliae (Robertson) —. Female: Mouthparts bare (Fig. 8); mesobasitarsus parallel-sided, width at midpoint subqual to apex (Fig. 9). Male: Posterior margin of propodeal dorsum imbricate (Fig. 13); metatrochanter with ventral angle obtuse (Fig. 14); metasomal sternum six with oblique submedial swellings acarinate (Fig. 15) (specialist on Monarda) ................................................................................... D. monardae (Viereck) 4(2). Both sexes: Mesoscutum shiny, sparsely punctate across disc. Female: Clypeus with coarse punctures evenly distributed across surface (Fig. 16); mesotibial spur long, more than half as long as mesobasitarsus (Fig. 17). Male: Posterior margin of metasomal sternum five concave (Fig. 18); sternum six with low submedial ridge on each side of medial carina (specialist on Potentilla) ...................... .................................................................................................... D. harveyi (Cockerell) —. Both sexes: Mesoscutum dull, contiguously punctate across disc. Female: Clypeus with fine punctures concentrated basally, clypeus impunctate apicomedially (Fig. 19); mesotibial spur short, less than half as long as mesobasitarsus (Fig. 20). Male: Posterior margin of metasomal sternum five straight (Fig. 21); sternum six without submedial ridge on each side of medial carina (specialist on Helianthus) ......................................................................... D. marginata (Cresson)

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.
