The Meniscus midges of Costa Rica (Diptera: Dixidae)
Bibliographic record
Abstract
A revision of the Dixidae of Costa Rica indicates that 10 named species of Dixella are present, eight of which are described as new (described stages indicated): D. fernandezae (%), D. hansoni (%), D. hernandezi (%), D. jironi (%), D. lobata (%, &), D. maculata (%, &), D. suzukii (%, &), D. woodi (%). Two named species were previously known from Costa Rica: D. shannoni Lane (%, &) and D. venezuelensis Lane (%, &). A key to the species of Costa Rica is provided and other similar Neotropical species discussed. An overview of all Central American species is given. Five of the 10 Costa Rican species were collected above 1200 meters in elevation, indicating that further collecting, especially at high elevations will reveal further species. Five additional species from Costa Rica remain unnamed because they are represented only by females. A total of 15 species of Dixella are therefore present in this country.
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.
