Abstract
Dufourea harveyi (Cockerell), new status (Figs. 3, 5, 16–18) Halictoides Harveyi Cockerell, 1906: 223 (♀). Dufourea (Halictoides) fimbriata fimbriata (Cresson): Michener, 1951: 1131 (catalog, synonym by G. E. Bohart); Hurd, 1979: 1935 (catalog); Moure & Hurd, 1987: 19 (catalog). Dufourea fimbriata (Cresson): Dumesh & Sheffield, 2012: 15 (♀ ♂ redescription [in part]). This species has commonly been understood to be D. fimbriata (Cresson, 1878), based on a synonymy proposed by G. E. Bohart in Michener (1951) and subsequently used by later authors (Hurd, 1979; Moure & Hurd, 1987; Dumesh & Sheffield, 2012). This concept is in error based on study of the Cresson type by one of us (T. L. G.). Dufourea fimbriata is more closely related to D. marginata (Cresson). Dufourea harveyi is not previously recorded from Michigan or nearby states. Dufourea harveyi is widespread in the western USA and Canada in alpine and boreal areas (Hurd, 1979; Moure & Hurd, 1987; Dumesh & Sheffield, 2012). In the United States it was previously known only as far east as Colorado (Cockerell, 1906; Hurd, 1979; Moure & Hurd, 1987), but has recently been recorded from Ontario, Canada (Dumesh & Sheffield, 2012). New state records for Michigan are as follows: Barry Co.: Yankee Springs Game Area, 16 August 1960 [MSUC]; Jackson Co.: Liberty, Grand River fen, 4 August 2009, 31 August 2009 [MSUC]; Kalamazoo Co.: Gull Lake Biological Station [formally the W. K. Kellogg Biological Station], 19 August 1960 [MSUC] (Fig. 24). These are the first published records of the species in the eastern United States. The easternmost record for the species is from Jackson County, Michigan. An earlier Ontario record (N50.8729, W84.5797) is nearly 940 km due north of Jackson County (Dumesh & Sheffield, 2012). Dufourea harveyi is believed to be an oligolege on Potentilla L. (Asteraceae), including Potentilla glandulosa Lindl., but has also been recorded visiting Achillea millefolium L. (Asteraceae), Dasiphora fruticosa (L.) Rybd. (Rosaceae), Penstemon Schmidel (Scrophulariaceae), and Polemonium L. (Polemoniaceae) (Hurd, 1979; Lincoln, 1981; Moure & Hurd, 1987). Species of Potentilla have been recorded from all 83 counties in Michigan; but P. glandulosa is not one of them (Reznicek et al., 2011). Individuals fly from late June to late August.

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.
