Abstract
Nartus Zaitzev, 1907, status re-instated Nartus Zaitzev, 1907: 103; type species: Dytiscus grapii Gyllenhal, 1808: 505 by monotypy. Diagnosis. Medium sized (9–12 mm) species. Medial labral emargination shallow. Sides of pronotum mostly distinctly bordered except for anterior angles; base of pronotum strongly sinuate, thus posterior angles of pronotum produced backwards, acute (Fig. 4A, arrow). Elytral reticulation double, consisting of large polygonal meshes filled with fine polygonal cells. Setae on parameres distally acute. In contrast to most species of Rhantus and related genera, both members of Nartus are totally black. Position. In Morinière et al. (2016), Nartus was recovered as the sister group of Rhantus as newly defined here, and we suggest that the original use of Nartus at generic rank is justified by our studies (Fig. 1). Species composition. Holartic genus comprised of two species: Nartus grapii (Gyllenhal, 1808), Europe (Fig. 4A). Nartus sinuatus (LeConte, 1862), Canada, northern USA.

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.
