Abstract
Orthonevra bellula (Williston, 1882) Chrysogaster bellulus Williston 1882: 304. Type-locality: USA, California (LT male USNM here designated). Chrysogaster bellula. Williston 1887a: 36, figs (head, wing) (description), 1891: 7 (Mexico, Durango, Michocán, difference from nitida); Aldrich 1905: 348 (catalog citation); Kertész 1910: 31 (catalog citation); Fluke 1957: 49 (catalog citation). Chrysogaster (Orthonevra) bellula. Sedman 1964: 170, figs (eye, mesonotum, wing) (key reference, descriptive note, distribution). Orthonevra bellula. Thompson et al. 1976: 91 (catalog citation). Figs 5 and 6 Differential diagnosis. Pile of the face long and scale-like (Fig. 5f); eye with sub-anterior vitta straight dorsally and sinuous ventrally, and middle straight vitta and complete fascia; scutum with 4 long more matte and darker vittae, without any other shorter vittate maculae laterally (Fig. 5b, e); wing with narrow faint dark vitta from end of R2+3 to R4+5, and on anterior half of M1; male surstyli symmetrical, with dorsal short triangular lobe and long ventral lobe. Length. Body 5.73–6.41mm (n=3), wing 4.32–4.82mm (n=3); female 5.83–6.89mm (n=3), wing 4.53–5.44mm (n=3). Distribution. USA (Washington to Idaho and South Dakota, south to California). Comments. The lack of a lateral dark vittate macula on the scutum is unique among the species studied. The female genitalia are illustrated for the first time (Fig. 6). No map was generated for this species since it is restricted to the Nearctic region. Material examined: USA. California, Vacaville, 1.x.1950, A.T. McClay (2 males CNC, CNC _ Diptera 91362– 3); Shasta, Shingleton, 2.vi.1941, P.D. Hurd (1 female CNC, CNC _ Diptera 91364); Walnut crk, ??.iii.????,?

Maddock (2 males CNC, CNC _ Diptera 91358, …91361); Moab, 8.v.1941, G.F. Knowlton & F.C. Harmston (1 female CNC, CNC _ Diptera 91365); Promontory, 5.x.1942, G.F. Knowlton & W.E. Peay (1 male CNC, CNC _ Diptera 91360).

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.
