The unknown larva of the burrowing water beetle genus <i>Liocanthydrus</i> Guignot, 1957 (Coleoptera: Noteridae)
Bibliographic record
Abstract
The instar III larva of Liocanthydrus clayae (J. Balfour-Browne, 1969) is described and illustrated, including morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment, and urogomphus. Larvae of Liocanthydrus Guignot, 1957, can be readily separated from other known noterid larvae by the presence of two short posterodorsal projections on the last abdominal segment. Regarding chaetotaxy, Liocanthydrus differs from Suphis Aubé, 1836, Hydrocanthus Say, 1823 and Suphisellus Crotch, 1873 in the position of seta AN7, the shape of seta CO13, the shape and length of setae FE6 and TI7, and the length of seta UR8.
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.
