Abstract
Pachystilicus quadriceps (LeConte, 1880) Fig. 3 Stilicus quadriceps LeConte, 1880: 178 (original description, key, notes). Pachystilicus quadriceps – Casey 1905: 227 (redescription). — Leng 1920: 104. — Lucas 1920: 475 (genotype fixed). — Blackwelder 1952: 285 (notes). — Moore & Legner 1979: 112. — Poole & Gentili 1996: 370. — Newton et al. 2001: 387 (comment on taxonomic status). — Bousquet et al. 2013: DwC-A database. Diagnosis Differs from P. hanhami by longer and denser setae covering body, longitudinal carina of basisternum more elevated. Additionally, median emargination of posterior margin of sternite VIII is deeper and broader than in P. hanhami, depth of emargination of ca ¼ of sternite length. Type material Lectotype (designated here) USA • ♂; “ Cal. / ♂ / Type 6584 / S. quadriceps Lec. / J.L. LeConte Collection ”; MCZ. Additional studied material CANADA – British Columbia • 1 spec.; “ Mts. Between Hope and Okanagan B. C. Sept. 90 / F C Bowditch Coll. / Stilicus quadriceps Lec ”; MCZ. USA – California • 1 spec.; “Cala / Coll Hubbard and Schwarz / quadriceps Lec ”; NMNH. – Massachusetts • 1 spec.; “ Brookline Mass 4-14-88 / F. C. Bowditch Coll ”; MCZ. Redescription MEASUREMENTS. Body length: 5 mm; forebody length: 2.75–2.90 mm. COLOURATION. Dark brown to reddish brown; head darker, legs and antennae reddish brown (Fig. 3A). HEAD. As in generic description (HL: 0.95–1.00 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. THORAX. As in generic description (pronotal size: PL: 0.8–0.9 mm; PW: 0.8–0.9 mm; elytra size: EL: 1 mm; EW: 1.1–1.2 mm). ABDOMEN. As in generic description; sternite VII with apical margin straight. Distribution The species has previously been recorded from the following US states: California, Massachusetts, and Missouri (Newton 2018). We newly report this species from the Canadian province of British Columbia.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
