Abstract
Key to Groups of New World Hydraena 1 Posterior ridge of genae present, at least laterally (e.g., Figs. 2 c, 2d); abdominal intercoxal ventrite various; scintilla absent ... 2 1' Posterior ridge of genae absent (e.g., Figs. 44, 126) or nearly imperceptible; abdominal intercoxal ventrite flat, with posterior margin straight or weakly arcuate; scintilla (Fig. 2 b) present or absent........................................... 5 2 Elytra and labrum with spines (Figs. 21, 22); elytron with five rows of punctures between suture and humerous; two species from South America ...................................................................... Multispina Group 2' Elytra and labrum without spines; elytron with more than five rows, or with many random punctures................... 3 3 Abdominal intercoxal ventrite concave, with posterior margin markedly arcuate; elytral punctures serial or, in few adults, with few random punctures on disc; spermatheca C-shaped; female gonocoxite not divided; Canada and the United States ............................................................................................... Circulata Group 3' Abdominal intercoxal ventrite flat, with posterior margin straight or weakly arcuate; elytral punctures random, at least near base; spermatheca disc-shaped (e.g. Figs. 151–154) or (in H. paeminosa) trilobed (Fig. 155); female gonocoxite divided (Figs. 148–150); South America .............................................................................. 4 4. Elytral punctures coarse and very random (e.g., Fig. 3); pronotum more elongate; mesoventral intercoxal process (P2) very narrow, tapering to sharp point that is contiguous with midlongitudinal carina of metaventrite (e.g., Fig. 2 c).................................................................................................... Paeminosa Group 4'. Elytral punctures serial except in small area at base (Figs. 16–18); pronotum less elongate, sides more sinuate; mesoventral intercoxal process (P2) wide, apex blunt (e.g., Fig. 2 d)............................................ Curvosa Group 5 Pronotal scintilla (Fig. 2 b) present or absent; pronotum always with posteromedial foveae (PF2; Fig. 2 a)...... Leechi Group 5' Pronotum never with scintilla; pronotum without posteromedial foveae, or if present very shallow and pronotum coarsely punctate (e.g., Figs. 110, 118)........................................................... Marginicollis Group

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.
