New record size, increased distribution range, and threat category reassessment proposal for Tropidophis morenoi (Squamata: Tropidophiidae)
Bibliographic record
Abstract
The Zebra Trope, Tropidophis morenoi Hedges, Garrido and Díaz, 2001, is one of 17 currently recognized species of Cuban dwarf boa (Díaz and Cádiz 2020), with a north central Cuba distribution (Henderson and Powell 2009, Rodríguez-Schettino et al. 2013; Figure 1A).This snake was previously placed in the T. maculatus species group by Hedges (2002), but Díaz and Cádiz (2020) transferred it to the T. pardalis species group.It is not well represented in museum collections and was described on the basis of two specimens (CZACC 4.5492-93) from Dolinas de Cueva de Humboldt, Caguanes, Sancti Spíritus province (Hedges et al. 2001).A third specimen (CZACC 4.12052) was reported from the type locality, which was a size record for species (Domínguez et al. 2006).Later, Domínguez and Parada (2009) reported new localities for this species including Loma de Cunagua, Bolivia municipality and Alevinaje, Morón municipality, both from Ciego de Ávila province; and Coco Key from Sabana-Camagüey archipelago (specimens CIEC 66-67; CIEC 150, respectively).That provided the first records for Ciego Ávila province on the main island and Sabana-Camagüey archipelago, extending the distribution range 75.6 km E from the type locality at Caguanes.With that addition, Coco Key was shown to harbor the highest number of Tropidophis species among Cuban keys (Domínguez and Parada 2009, Rodríguez-Schettino et al. 2013).Additionally, a specimen (MNHNCu 5088) from Jobo Rosado, Jatibonico municipality, Sancti Spíritus province was reported by Díaz and Cádiz (2020), extending the distribution range 17.4 km SW from Caguanes.

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.
