Checklist and distribution atlas of the Scarabaeinae (Coleoptera: Scarabaeidae) of Costa Rica
Bibliographic record
Abstract
The 182 species of Scarabaeinae known to occur in Costa Rica are listed with synonymies included. We place Uroxys mac-rocularis Howden & Young as a synonym of U. boneti Pereira & Halffter (new synonym); we also place Uroxys depres-sifrons Howden & Young as a synonym of U. pauliani Balthasar (new synonym). We conducted a mitochondrial DNAcytochrome oxidase I barcoding analysis in order to clarify some taxonomic uncertainties with Phanaeus pyrois Bates andSulcophanaeus noctis (Bates). We elevate Phanaeus pyrois malyi Arnaud to Phanaeus malyi and revalidate Phanaeus ex-celsus Bates as valid species. We consider the species Dichotomius nevermanni Luederwaldt as incertae sedis. A CostaRican distribution map is provided for all species except Dichotomius costaricensis, which is only known from a countryrecord. We report, map, and estimate the spread of the invasive species Euoniticellus intermedius (Reiche) for Central America, from Chiapas to Costa Rica.
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.
