Abstract
Lionothus Brown Lionothus Brown, 1937: 170. Type species: Lionothus ulkei Brown, 1937; by original designation. Daffner 1988: 288. Pseudocyrtusa Portevin, 1942: 78. Type species: Pseudocyrtusa australis Portevin, 1942, by monotypy; synonymy by Newton 1983: 175. Diagnosis. Body convex. Antenna with 11 antennomeres with 5-antennomere club interrupted at antennomere 8, which is narrow and disc-shaped but clearly visible. Mandibles variable, left mandible usually with one or two small blunt teeth on anterior one-third. Ventral side of head with or without well defined antennal grooves. Mesosternum vertical between mesocoxae, not carinate. Tibiae uniformly widened to apex; protibiae with tarsal grooves; outer margins of all tibiae with strong spines. Tarsal formula 5-5- 4 in both sexes. Abdominal sternites III–VII each with basal transverse row of large punctures. Males are distinguished by larger, often sinuate spur on inner apical margin of usually straight mesotibia; inner apical margin of mesotibia not produced; and apical tooth-like expansion of the lower margin of the metafemur. Distribution. The distribution of the genus is Nearctic and northern Neotropical (Mexico, Colombia) (Newton 1998). Key to species of male Lionothus of the continental United States and Canada 1.

L. forticornis Daffner – Antennal grooves not well defined, outer margins not demarked by carinae ............................ 4 4(3). Mandibles short, together forming semicircle, left mandible with 2 small teeth on apical onethird; eye of normal size, about half length of head ..

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.
