Abstract
18. Tropicus pusillus (Say) (Fig. 26, 27, 53, 71) Heterocerus pusillus Say 1823: 200. Tropicus pusillus (Say): Pacheco 1964: 137. Description. Length 2.3 - 3.0 mm. Orange-brown. Elytra orange laterally, with a common brown macula medially (Fig. 26). Males with a process extending from the dorso-lateral edge of each mandible that wraps around the edge of the labrum (Fig. 27), often nearly meeting the process from other side. Postmetathoracic coxal and post-mesothoracic coxal lines absent. Male genitalia (Fig. 53) of the typical Tropicus type, dorsal edge projecting anteriorly. Diagnosis. Tropicus pusillus can be easily distinguished from all species of southeastern heterocerid by color pattern alone. The elytra are not trifasciate, as they are in southeastern Heterocerus, but have brown sutural margins. Together, these darker margins produce a rather even-edged median macula on the elytra. This coloration also easily distinguishes T. pusillus from its only southeastern congener, Tropicus nigrellus n. sp., which is entirely black. Notes. Often the most numerous beetle at a UV light placed near a body of water in the southeastern U.S., T. pusillus is the only species of heterocerid consistently collected from intermittent creek beds, drainage ditches, and sandy ponds. During this project, specimens were collected from the margin of a brackish marshy habitat on the campus of the Gulf Coast Research Laboratory in Ocean Springs, Mississippi. Distribution. Tropicus pusillus occurs from near the Canadian border south to Panama and Cuba. It was collected in all 63 Mississippi counties where UV lights were run as part of this project, as well as from most Alabama collection localities sampled by Harris et al. (1991, Fig. 39). Specimens examined. 1802 (See Appendix).

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.
