Abstract
ABSTRACT The viperid genus Cerastes contains four desert‐adapted species distributed throughout the Saharo‐Arabian arid belt that are typically associated with loose sands. Cerastes boehmei is restricted to one locality in Tunisia and is known only from the holotype. Since its description, it has been speculated that this species, which exhibits distinctive horn‐like supraocular scales, could be an aberrant specimen of another desert‐adapted viper of the same genus, C. vipera . In this study, we present genetic data from the holotype specimen of C. boehmei for the first time. We used Sanger and Illumina sequencing and obtained sequences for three mitochondrial genes (12S, 16S, cytb) and three nuclear genes (MC1R, NT‐3, VIM) and constructed two separate phylogenetic trees based on these data sets. Additionally, we generated a phylogenetic analysis based on the coding regions of mitogenomes of all the Cerastes species. The analyses of both the mitochondrial and the nuclear data clearly show that the C. boehmei holotype is nested within C. vipera . Based on our results, we formally synonymise Cerastes boehmei Wagner & Wilms, 2010 with Cerastes vipera (Linnaeus, 1758). This taxonomic revision is supported by robust genetic evidence and will help to resolve the long‐lasting debate concerning the validity of the species.

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 it
