EXCEPTIONAL DIVERSITY OF STEFANIA (ANURA: HYLIDAE) ON MOUNT AYANGANNA, GUYANA: THREE NEW SPECIES AND NEW DISTRIBUTION RECORDS
Bibliographic record
Abstract
Herpetological survey on Mt. Ayanganna in west-central Guyana resulted in the discovery of five species of Stefania occurring syntopically at about 1500 m. Two additional species occur at the base of the mountain. We describe three new species of Stefania and provide redescriptions and range extensions for four other Stefania. The number of Stefania known from Guyana increases from three to seven species. Resumen Cinco nuevas especies de Stefania han sido descubiertas tras un reconocimiento herpetológico llevado a cabo en el Monte Ayanganna en la Guyana centro occidental. Las cinco especies han sido halladas en torno a los 1500 m de altitud. Dos especies mas han sido halladas en la base de la montaña. Se describen aquí tres especies nuevas de Stefania halladas. Para las restantes cuatro especies se recoge su redescripción así como el área de distribución. El número de especies conocidas de Stefania aumenta de este modo de tres a siete especies.

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.
