Bibliographic record
Abstract
<i>Sympistis chons</i> Troubridge sp. n. (Figs. D-18, D-19, D-20, M-7, R-4) <b>Diagnosis.</b> <i>Sympistis chons</i> can be distinguished from <i>S. amun</i> by the characters given above, except in the Peace River Valley, British Columbia and Alberta, where <i>S. chons</i> is very dark and looks much like <i>S. amun</i>. DNA analysis puts these northern specimens with <i>S. chons</i>. This species becomes paler towards the south, where the forewing is light gray and the hindwing marginal band almost absent in some Arizona specimens. On the Great Plains, <i>S. chons</i> occurs in badlands and dry river valleys and <i>S. riparia</i> occurs on dunes. The subterminal line of <i>S. riparia</i> is present as an undulating pale line or series of pale dots (Figs. E-2, E-3); that of <i>S. chons</i> is more deeply jagged, particularly in the anal angle. In the south, <i>S. chons</i> could be confused with <i>S. deserticola</i> or <i>S. major</i>. The orbicular and particularly the claviform spots of <i>S. deserticola</i> (Fig. D-12) and <i>S. major</i> (Figs. D-13, D-14) are highlighted with white scales; these spots are less contrasting and light gray rather than white in <i>S. chons</i>. <b>Description</b>. Antennae filiform, prothoracic collar hoary charcoal gray with wide, light gray median band diffuse charcoal median line within the median band; head and thorax a mix of black and light gray scales gives a hoary dark gray appearance; abdomen light grayish brown. Coremata with brushes, levers, and pockets present on base of male abdomen. Forewing length 15-17 mm. <b>Dorsal forewing</b> light gray and black scales give forewing powdery gray appearance; antemedial and postmedial lines usually obscure, absent, or present as black dots on veins; orbicular spot ellipsoidal; orbicular, reniform, and claviform spots dark gray, bordered with light gray or scattered white scales on the inner row and thin black outer row of scales; thin black basal dash extends into claviform spot; black lines extent through each cell in subterminal portion of wing, meeting black terminal line which is present as a series of small chevrons between veins; slightly obscure, white subterminal line deeply denticulate; fringe dark gray, lightly checkered with light gray at tips of veins. <b>Dorsal hindwing</b> very light grayish basal area blends to dark grayish brown terminal shade in male, slightly darker in female; veins and discal lunule highlighted with scattered grayish brown scales; fringe white with narrow gray median line. <b>Male genitalia</b>. (Fig. M-7) Valve shaped like the prow of a canoe with distinct corona; ampulla of clasper squat, bends posteriorly with terminal spine arcing upward from posterior margin. Vesica with two small basal diverticulae, bends slightly downward about ½ of the way from base; a ribbon of sparse cornuti extends dorsally from base of vesica to apex; a second ribbon of longer, stouter cornuti extends dorsolaterally on right of apical ½ of vesica; a single spine and a tuft of longer cornuti extend from apex. <b>Female genitalia</b>. (Fig. R-4) Ovipositor lobes rounded, apex with ring of long setae, corona of short setae mid way down -these setae produced at 90° to the abdomen; a ruff of longer, finer setae encircles ovipositor lobes at base; a small sclerite occurs on ventral surface of ductus bursae at ostium bursae, ductus bursae elongate, widening slightly in middle ½ and then narrowing at appendix bursae; appendix bursae elongate gradually narrows toward ductus bursae, rounded at anterior end with ductus seminalis arising from ventral side of anterior end; corpus bursae about ½ as large as appendix bursae arises from left side of appendix bursae near ductus bursae, elongate signae on dorsal and ventral sides. <b>Type material</b>. <b>Holotype</b> male: Canada, British Columbia, Kirby Flats Rd., 50° 32' N, 121° 43' W, 7 vii 2000, J.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
