Abstract
Hydrotrupes chinensis Nilsson, 2003 Nilsson, A.N. (2003), ‘Dytiscidae. XII. A New Species of Hydrotrupes Sharp from China, an Example of Pacific Intercontinental Disjunction (Coleoptera)’, in Water Beetles of China (Vol. 3), eds. M.A. Jäch and L. Ji, Vienna: Zoologische-Botanische, Gesellschaft, pp. 284–297. [Google Scholar] described from the holotype collected in Anhui Province, China, is newly recorded from three localities in Guangdong Province, ca. 750 km southwest from the type locality. The species seems to inhabit hygropetric habitats exclusively, with diurnal larvae and nocturnal adults hidden under stones or in cracks in rock during the day; when disturbed, the adults readily jumped off the rock surface. The adult is redescribed. The larvae are described and illustrated for the first time, with detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment, and urogomphi. Whereas similar morphologically to the Nearctic endemic Hydrotrupes palpalis Sharp, 1882 Sharp, D. (1882), ‘On Aquatic Carnivorous Coleoptera or Dytiscidae’, Scientific Transactions of the Royal Dublin Society, 2, 179–1003. [Google Scholar], the first instar larva of H. chinensis distinguishes by presence of six lamellae clypeales, two additional spine-like setae both on the last abdominal segment and urogomphomere 1, and the strongly developed egg bursters.

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
