Abstract
Pachystilicus hanhami (Wickham, 1898) Fig. 4 Stilicus hanhami Wickham, 1898: 220 (original description, notes). Pachystilicus hanhami – Casey 1905: 227 (redescription). — Blackwelder 1939: 107, 120; 1952: 285 (notes). — Poole & Gentili 1996: 370. — Webster 2016: 435. — Newton et al. 2001: 387 (comment on taxonomic status). Diagnosis Differs from P. quadriceps by shorter and slightly sparser setae covering body, longitudinal carina of basisternum less elevated. Additionally, the median emargination of posterior margin of male sternite VIII is shallower and narrower than in P. quadriceps, with the depth of emargination ca 1/5 of sternite length.

Body length: 4.5 mm; forebody length: 2.70–2.95 mm. COLOURATION. Dark brown to yellow; head darker, legs and antennae reddish brown, elytra (except for base) light brown to yellow. Abdomen black, tip lighter in colour (Fig. 4A–B). HEAD. As in generic description (HL: 0.9–1.0 mm; HW: 1.0– 1.1 mm), with antennomere 1 elongate, widest at tip; antennomeres 2–4 elongate; antennomere 5 weakly elongate; antennomeres 6–10 gradually becoming transverse; antennomere 11 elongate, 1.5× as long as antennomere 10.

How this classification was reachedexpand
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.
