Abstract
Tribe Sericoidini Diagnosis. The tribe Sericoidini is distinguished from other Melolonthinae using the following combination of characters: labrum beneath clypeus, not on same plane; clypeus and labrum separate (with labrum protruding beyond clypeus in dorsal view) or fused (with a suture distinguishing the parts); antenna with 8-9 antennomeres (including 3-5 antennomere club); mesosternal / metasternal process absent; abdomen with 6 ventral sternites (basal sternite partially hidden by metacoxae), sternites approximately equal in length, evenly convex, separated by distinct sutures; tergite and ventrite of abdominal segments entirely distinct, separated by complete longitudinal suture or ridge (absent in Ulata); metatibiae with 2 apical spurs, spurs set below and above the tarsal articulation (tarsus moves between tibial spurs); all claws symmetrical. Remark. The definition of the tribe Sericoidini is refined above and now includes the following genera: Apterodemidea Arrow, Blepharotoma Blanchard, Sericoides Guérin-Méneville, and Ulata Saylor. The tribal status of Apterodemidea and Ulata is somewhat unclear and warrants further investigation. Sericoidini is endemic to the southern half of South America and shares characters with several Australian tribes including Automoliini, Liparetrini, Maechidiini, Scitalini, etc.

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.
