Skinks currently assigned to Carlia aerata (Scincidae : Lygosominae) of north-eastern Queensland: a preliminary study of cryptic diversity and two new species
Bibliographic record
Abstract
A preliminary investigation of genetic diversity in Carlia aerata, by sequencing the mitochondrial ND4 gene, revealed the presence of two cryptic species, described herein. The sequence data was added to an existing phylogeny to discern molecular relationships. Interestingly, genetic affinities lie not with C. aerata, the species to which they key. Instead, one has affinities with C. tanneri, the other with C. foliorum. This casts doubt on the validity of morphological characters alone to infer relationships within this genus. Despite low levels of genetic divergence from sister taxa, the new species can be diagnosed from these by morphological characters that exhibit little or no intraspecific variation. The addition of these new species to the gene tree did not enhance resolution of the phylogenetic relationships at the deeper nodes of the Carlia tree. The discovery of these two new cryptic species provides further support for a previously suggested rapid mid-Miocene diversification of Carlia that may have resulted from the successful expansion of a rainforest-dwelling ancestor into the expanding woodlands associated with Miocene climate fluctuations.

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.
