Abstract
Based on the available literature (Nguyen & David 2023; Liu et al. 2023) and our own material, we here propose the following provisional identification key to the species of the Rhabdophis nuchalis group species: 1a. Dorsal scale rows 15–15–15............................................................................. 3 1b. Dorsal scale rows 17–17 (15, 16)–15..................................................................... 2 2a. Ventrals 136–151; infralabials 7; temporals 1+2; maxillary teeth 25................................... R. hmongorum 2b. Ventrals 151–157; infralabials 8; temporals 1+1; maxillary teeth 19.............................. R. leonardi complex 3a. Usually supralabials 5.................................................................................. 4 3b. Usually supralabials 6.................................................................................. 5 4a. Dorsum green; venter pale............................................................. R. pentasupralabialis 4b. Dorsum brown; venter dark...................................................................... R. chiwen 5a. Black line present below the eye and extending onto the last two supralabials..................................... 6 5b. Black line absent below eye and on last two supralabials.......................................... R. kaiyuanensis 6a. Distinct mark present on nape........................................................................... 7 6b. Nape without V-shaped black patches............................................................. R. nuchalis 7a. TEM usually 1+1; VEN 118–127; SC 38–47; nape grey with an orange V-shaped zone behind the black collar; faint dorsolateral cross-bars present............................................................................ .. R. angeli 7b. TEM usually 1+2; VEN 124–165; SC 44–74; nape reddish-brown before the black collar, without an orange V-shaped zone; dorsolateral cross-bars absent.................................................................. R. swinhonis

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.
