Bibliographic record
Abstract
Platyhydnobius andersoni Peck & Cook, new species (Figs. 156–159, 160) Type material. Holotype: ♂ (CMNC). MEXICO: Chiapas State: Mpio. (Municipio) Tapalapa, Cerro El Calvario, near Tapalapa, 17°11'11.9"N, 93°07'21.0"W, 23.VII.2003, 2200 m, R. Anderson, 2003-118, wet cloud forest litter. Paratypes (4): MEXICO: Chiapas State: with same data as holotype, ♂, 3♀♀ (SBPC). Diagnostic description. Reddish brown, shining; elytral bases with a narrow transverse yellow band; elytral epipleurae yellow. Length of pronotum + elytra = 3.0–3.4 mm (males), 3.4 mm (females). Head moderately coarsely, densely punctate. Pronotum broad, widest at base, sides weakly rounded, basal angles nearly right-angled; ratio length:width = 1:1.9; moderately coarsely, densely punctate. Elytra short, wider than pronotum, ratio length:width = 1:0.9; 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. 156) slender, ratio club width:length = 1:3.7; width ratio of antennomeres 7:8:9 = 1.4:1:1.5. In both sexes, all femora unarmed; all tibiae slender, spinose on outer margin, protibiae and mesotibiae weakly widened apically, male mesotibia weakly curved. Male. Aedeagus (Fig. 157) with median lobe elongate, apex rounded. Parameres longer than median lobe, flat, with small lateral lobes near base. Paramere apices thin, weakly expanded, with a single dorsal seta and many small setae apically. Female. Coxites (Fig. 159) elongate, narrow, with apical and subapical setae; styli elongate, inserted at apices of coxites. Sternite 8 (Fig. 158) rounded apically; anterior apophysis narrowing to rounded apex. Bionomics and distribution. Known only from cloud forest litter in July at the type locality (Fig. 160). Etymology. Named in recognition of the collector, Dr. Robert S. Anderson, entomologist of the Canadian Museum of Nature, and an assiduous collector of litter inhabiting beetles in Central America.
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.
