A NEW ERICHSONIUS SPECIES FROM ARIZONA WITH DISCUSSION ON PHYLOGENY WITHIN THE GENUS (COLEOPTERA: STAPHYLINIDAE)2
Bibliographic record
Abstract
Erichsonius antiquus Frank, a new species from the Chiricahua Mountains of Arizona, U.S.A., is described and distinguished from known New World species of Erichsonius. New state or provincial distributional records are given for 6 other New World Erichsonius species. Two subgenera were recognized among Old World Erichsonius (Erichsonius s. str. and Sectophilonthus Tottenham (= Parerichsonius Coiffait, NEW STATUS, NEW SYNONYMY)); these are redefined and redelimited, and the New World species are assigned. In the summer of 1976, Peter Hammond (British Museum (Natural History)) visited Canada and the United States and collected many specimens of Staphylinidae. I was asked to identify those specimens belonging to Erichsonius and to Neobisnius because of my interest in those genera. Among the Erichsonius were specimens of an undescribed species. This article was prepared to describe this new species and to record new distributional records resulting from some specimens I have identified since 1975. The specimens belong to the British Museum (BMNH) or to my own collection (JHFC). Knowledge of the new species, and examination of illustrations and descriptions of certain Old World species, prompted me to attempt subgeneric grouping of the Erichsonius species occurring in the New World as well as some of those occurring in the Old World.

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.
