Bibliographic record
Abstract
A new kukri snake, Oligodon culaochamensis sp. nov., is described from Cu Lao Cham Islands, central Vietnam, based on the morphology of six specimens, including two males, three females and one juvenile. The new species belongs to the O. cyclurus group and differs from other congeners in this group by a combination of the following characters: medium size in adults (total length up to 582 mm); 17–19 dorsal scale rows at neck and midbody and 15 or 17 rows before vent; tail length/total length ratio 0.218–0.219 in males and 0.166–0.169 in females; ventrals 167–169 in males and 179–182 in females; subcaudals 63–66 in males and 51–52 in females; head scalation complete with a presubocular; 9–10 maxillary teeth, the posterior three being enlarged; nasal divided; temporal streak absent; long and deeply forked hemipenes extending to 20th subcaudal and without spines and papillae but with prominent diagonal ridge, oblique flounces and distal calyces; cloacal plate undivided; 10–11+3–4 dorsal blotches; and a vertebral stripe on tail and anterior part of body. This is the second species of Oligodon described on islands of Vietnam.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
