Revision of the Nearctic<i>Silusa</i>(Coleoptera, Staphylinidae, Aleocharinae)
Bibliographic record
Abstract
Abstract A revision of the Canadian species of the genusSilusaErichson is presented. In this contribution, we treat six species recently discovered in Canada, one of which is a new species from Alberta,Silusa langoriKlimaszewskisp. nov.The distribution records for two species are greatly expanded.Silusa californicaBernhauer is now known from Alaska, Minnesota, Alberta, Quebec, New Brunswick, and Nova Scotia (previous records: British Columbia, California).Silusa vesperisCasey is now known from Washington and British Columbia (previous record: California). For two other species, there are first records for Canada and one new United States state record.Silusa alternansSachse is now known from Quebec, New Brunswick, Nova Scotia, and New Hampshire (previous records: Georgia, New York), andSilusa densaFenyes is now known from Alberta (previous record: California).Silusa valensCasey is here considered as a synonym ofS. alternans.Silusa rutilansCasey andS. modicaCasey are confirmed to belong toLeptusaKraatz, and both are here considered as new synonyms ofLeptusa canonicaCasey.Silusa gracilisSachse andS. nanulaCasey are also confirmed to belong to the genusLeptusa. The following lectotypes are newly designated for species described on the basis of syntypes:S. alternansSachse andS. californicaBernhauer. New data are provided on the systematics, relationships, bionomics, and distribution for all Nearctic species of America north of Mexico. Diagnoses and illustrations of external and genital features are provided for all species, and the distribution of each is discussed and shown on maps. A key to the species occurring in Canada is presented.
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.
