Revisiting Brundin’s collection, part I – larval description of three species of the genus <i>Podonomus</i> (Diptera: Chironomidae: Podonominae) with identification key for known larvae
Bibliographic record
Abstract
Podonomus is one of the richest genera of Podonominae, with 44 species described. With wide distribution in South America, Podonomus species are an important component of aquatic ecosystems such as streams and madicolous habitats. However, its larval stages have been historically overlooked, with only six species described. After visiting Brundin’s collection, we were able to recover information on larvae of three species mentioned in his monograph. Here we describe the larvae of P. apolobambae and P. setosus, provide a broad description of the P. albinervis larva and present an identification key to the known larvae of the genus, including the other five species whose larvae are described, P. amarali, P. fastigians, P. pepinellii, P. quito and P. tehuelche.
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.
