Bibliographic record
Abstract
Platyhydnobius howdenorum Peck & Cook, new species (Figs. 160, 165–166) Type material. Holotype: ♂ (CMNC). MEXICO: Chiapas State: San Cristobal, 26–27.V.1990, 2200 m, H. and A. Howden, B. Gill. Paratype: MEXICO: Chiapas State: with same data as holotype, ♂ (SBPC). Diagnostic description. Reddish brown, shining; elytral bases with a narrow transverse yellow band; elytral epipleurae yellow. Length of pronotum + elytra = 2.4–2.9 mm (males). Head finely, irregularly punctate with fine reticulate microsculpture. Pronotum broad, widest at base, sides weakly rounded, basal angles weakly obtuse; ratio length:width = 1:1.7; finely punctate with fine reticulate microsculpture. Elytra of medium length, wider than pronotum, ratio length:width = 1:0.74; with 9 regular, closely punctate striae; striae 6 and 7 do not reach apex, stria 8 does not reach base, stria 1 weakly impressed; intervals minutely punctate, transversely striolate. Antennal club (Fig. 165) moderately slender, ratio club width:length = 1:3.1; width ratio of antennomeres 7:8:9 = 1.3:1:1.8. All femora unarmed; all tibiae slender, spinose on outer margin, protibiae and mesotibiae weakly widened apically, mesotibia weakly curved. Male. Aedeagus (Fig. 166) with median lobe elongate, abruptly narrowed at apex, with small apical lobe. Parameres longer than median lobe, flat, with small lateral lobes near base. Paramere apices thin, inwardly curved, with two dorsal setae and many small setae apically. Female. Unknown. Bionomics and distribution. The type specimen was taken in late May in a mixed broadleaf oak-pine forest, probably in leaf litter, up the hill and behind Motel Molino, southeast of the city of San Cristobal (Fig. 160). Etymology. Named in honor of Henry and Anne Howden of Ottawa, of the Canadian Museum of Nature, extraordinary beetle collectors and systematists.
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.
