Abstract
Abstract Descriptions of the larval instars of four genera (12 species) of the dytiscid subfamily Laccophilinae, Laccophilus Leach, Neptosternus Sharp, Australphilus Watts and Africophilus Guignot, are presented including a detailed chaetotaxic and porotaxic analysis of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi. A parsimony analysis, based on the 13 informative larval characteristics was conducted with Hennig86. The genus Africophilus is postulated to represent the sister-group of a clade comprised of Laccophilus + (Neptosternus + Australphilus) which is supported by, (i) primary seta CO7 articulated proximally on all legs, (ii) presence of natatory setae, (iii) metatibia + metatarsus very elongated, and (iv) elongated urogomphi.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
