Biogeography and taxonomic status of Myotis keaysi pilosatibialis LaVal 1973 (Chiroptera: Vespertilionidae)
Bibliographic record
Abstract
We document the first confirmed Colombian records of Myotis keaysi pilosatibialis LaVal, 1973 from various localities on the Colombian Caribbean and the Eastern Cordillera of the Colombian Andes. These records confirm geographic overlap between M. k. pilosatibialis and the nominate subspecies M. k. keaysi J. A. Allen, 1914, in northeastern Colombia, questioning the subspecific status of M. k. pilosatibialis. Models of potential distribution, produced for the two taxa by the application of the Maxent algorithm, show a potential geographic overlap in the northeastern portion of the Andes of Colombia and Venezuela. In order to clarify the taxonomic status of putative M. keaysi variants, we analyzed the variation of Colombian representatives of M. keaysi through a Principal Components Analysis (PCA), and a Discriminant Function Analysis (DFA) performed on 18 cranio-dental measurements, as well as the analysis of discrete characters. The morphological independence between M. k. keaysi and M. k. pilosatibialis was supported statistically in our PCA and DFA, as well as by the presence of unique discrete characters, lending support to the recognition of M. k. pilosatibialis as full species. Herein, we include new discrete characters setting apart M. pilosatibialis from the morphologically similar species M. keaysi.

How this classification was reachedexpand
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.
