A new species of <i>Parochlus</i> (Diptera: Chironomidae) reveals intriguing features of larva at the oldest South American highlands
Bibliographic record
Abstract
At the summit of the highest Brazilian mountain, an intriguing species of Parochlus Enderlein, 1912 (Diptera: Chironomidae: Podonominae) was unveiled. This is also the first time that Parochlus specimens were recorded in Brazil. Members of the subfamily Podonominae are hardly found in Brazilian lands, hitherto represented only by a few Podonomus Philippi, 1865 (Diptera: Chironomidae) species limited to the Atlantic Mountains. The presence of the genus Parochlus in the oldest and northernmost region of South America represents a remarkable finding to advance our understanding about the diversity of Podonominae and its biogeographical disjunctive distribution. The female and the peculiar larva of this new species are fully described and illustrated.

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.
