The genus Crostis Casey (Coleoptera: Curculionidae: Baridinae) in North America
Bibliographic record
Abstract
The originally monobasic genus Crostis Casey, 1922 (type species Crostis subexplanata Casey, 1922 from Brazil) is redefined based on two named and approximately 15 unnamed species occurring between the southern United States and northern Argentina. Three oblong-ovate northern species here grouped informally as the Crostis boreas species group are described: Crostis boreas Prena Anderson new species from Arkansas and Texas in the U.S.A. and Quertaro and Tamaulipas in Mexico, Crostis boreodes Prena Anderson new species from Guanajuato and Michoacn in Mexico, and Crostis caperata Prena Anderson new species from Chiapas in Mexico. The South American Baridius thoracicus Kirsch, 1875 is transferred from Lamprobaris Champion, 1908 to Crostis, as Crostis thoracica (Kirsch) new combination.
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.
