Abstract

fetched live from OpenAlex

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. Mandible with three teeth on right and left mandible, but two outer teeth on right mandible much larger than others. THORAX. As in generic description (pronotal size: PL: 0.8–0.9 mm; PW: 0.8–0.9 mm; elytra size: EL: 1.00– 1.05 mm; EW: 1.2 mm). ABDOMEN. As in generic description; sternite III with short medial longitudinal keel. Distribution The species has previously been recorded from the Canadian provinces of Alberta, British Columbia, Manitoba, New Brunswick, and Saskatchewan and the US state of Oregon (Newton 2018). New records include the following US states: Massachusetts, New Hampshire, and Oklahoma.

Not 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.
