Systematics, distributions, and bionomics of the small carrion beetles (Coleoptera: Leiodidae: Cholevinae: Cholevini) of North America
Bibliographic record
Abstract
Abstract In North America, the tribe Cholevini (Coleoptera: Leiodidae) is composed of the generaPrionochaetaHorn with 1 species,CatoptrichusMurray with 1 species,SciodrepoidesHatch with 3 species, andCatopsPaykull with 17 species. The species are mostly forest inhabitants that feed on carrion and other decaying materials, but some occur in tundra habitats, in caves, and in rodent burrows. Resurrected status is proposed forSciodrepoides terminans(LeConte). The subspecies status ofSciodrepoides watsoni hornianus(Blanchard) is not supported. Lectotypes are designated forCatops terminansLeConte (=Sciodrepoides terminans(LeConte)),Choleva gratiosaBlanchard (=Catops gratiosus(Blanchard)), andCholeva egenaHorn (=Catops egenus(Horn)). Neotypes are designated forCatops simplexSay andCatops basilarisSay.Catops luteipesThomson is reported from North America for the first time. New species areSciodrepoides latinotumPeck and Cooksp.nov.,Catops paramericanusPeck and Cooksp.nov.,Catops apterusPeck and Cooksp.nov., andCatops meridionalisPeck and Cooksp.nov. FourCatopsspecies are Holarctic in distribution, whereas the others are restricted to North America, south to Mexico.

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.
