Proepimeral seta absent (Fig. 42) .............................................................. A. ruficauda Curran, 1929 – Proepimeral seta present (Fig. 6) ...................................................................................................... 3 3.

Male and female postpedicel with base narrowly yellow (Fig. 4); wing with infuscation around R 2+3 distal to cell dm (Fig. 7); lateral margin of scutum paler than medially ............................................. ................................................................................................................... A. albibarba (Loew, 1869) – Male postpedicel entirely yellow (Figs 21, 23); female postpedicel with base narrowly yellow; wing without infuscation around R 2+3 distally (Figs 22–23); scutum not paler laterally ............................. ......................................................................................................... A. nigrimana (Zetterstedt, 1846) 5. Wing without discal crossband; fore tibia with long, strong posteroventral seta on apical third, length twice width of tibia [male unknown] ................................................................ Acanthocnema sp. A – Wing with discal crossband (Figs 31, 37); fore tibia without long, strong posteroventral seta on apical third (Figs 30, 36) ............................................................................................................................. 6 6.

Male palpus yellow (Fig. 13), dark in female; male sternite 5 divided into pair of divergent lobes (Fig. 18); fore tibia usually with 1 posteroventral seta near mid-length, 1 preapical posteroventral seta, slender, as long as basal width of fore femur and row of short, strong, black anteroventral setae proximal to ventral spur ............................................................................. A. capillata (Loew, 1872) – Palpus pale to dark brown in both sexes (Figs 49–50); male sternite 5 not divided into pair of divergent lobes (Fig. 52); fore tibia with 0–1 posteroventral setae near mid-length, similar to ventral spur, without row of short, black anteroventral setae .................................... A. torrenticola sp. nov.

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.
