Review of the Genus<i>Cybister</i>Curtis, 1827 (Coleoptera: Dytiscidae: Dytiscinae: Cybistrini) in North America
Bibliographic record
Abstract
The genus Cybister Curtis (Coleoptera: Dytiscidae) in the Nearctic region is reviewed including taxonomic history, keys to species, diagnoses, illustrations, distributions, and natural history. Three species are recognized in the genus. Cybister explanatus LeConte, 1852 (= Cybister explanatus laevicollis Zimmermann, 1919; = Cybister explanatus fusculus Zimmermann, 1919) is found from southern Oregon through California and Nevada and through western Mexico to Chiapas. Cybister occidentalis Aubé, 1838 is found in Cuba, the Bahamas, and extreme southern Florida. Cybister fimbriolatus (Say, 1823) (= Cybister dissimilis Aubé, 1838; = Cybister flavocinctus Aubé, 1838 new synonymy; = Cybister ellipticus LeConte, 1852 new synonymy; = Cybister cavicollis Sharp, 1887 new synonymy; = Cybister crotchi Wilke, 1920) is found from southeastern Canada west to Ontario and North Dakota south through eastern North America to Florida and the Bahamas (Bahimi Island), west through the southern United States to Arizona and southern California and south throughout Mexico to the Yucatán. Lectotypes are designated for C. ellipticus and C. explanatus.
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.
