A new granite cave dwelling endemic species of the Cyrtodactylus intermedius group (Squamata: Gekkonidae) from Hon Son Island, Kien Giang Province, Vietnam
Bibliographic record
Abstract
During field work on Hon Son Island, we discovered a new species of the genus Cyrtodactylus inferred from genetic and morphological evidence. Phylogenetic analyses based on the mitochondrial gene ND2, delimit Cyrtodactylus borgattaorum sp. nov. as a new species in the C. intermedius group and the strongly supported sister species of C. phuquocensis in both Bayesian inference and Maximum Likelihood analyses. The new species is distinguished from all other members of the intermedius group by having the combination of 12 supralabials; 10 or 11 infralabials; 22 or 23 small, rounded, smooth, paravertebral tubercles; 12 rows of small, rounded, smooth, longitudinally arranged body tubercles; 35-39 ventrals; 8-10 expanded subdigital lamellae, 12 or 13 unexpanded subdigital lamellae, and 21 or 22 total subdigital lamellae on the fourth toe; 21 or 22 enlarged femorals; 8 or 9 enlarged precloacals; 8 or 9 precloacal pores in males; three rows of enlarged post-precloacals; postcloacal tubercles; enlarged femorals and enlarged precloacals not continuous; proximal femorals nearly same size of distal femorals; body tubercles smooth, greatly reduced; no pocketing between digits on the hands and feet; two dark-colored pigmented blotches on top of head; four dark-colored dorsal bands lacking lightened centers, thinner than light-colored interspaces between bands, bordered by prominent white tubercles; no dark body markings in light-colored interspaces between bands; limbs bearing white tubercles; and six dark-colored and light-colored caudal bands. Cyrtodactylus borgattaorum sp. nov. lives in syntopy with Cyrtodactylus eisenmanae which is the first record of syntopy between granite cave dwelling Cyrtodactylus.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
