Additions to the taxonomy of the armadillo ants (Hymenoptera, Formicidae, Tatuidris)
Bibliographic record
Abstract
The taxonomy of the rare ant genus Tatuidris is revised by studying morphological variability among 118 specimens from 52 collection events in 11 countries, and sequences of Cytochrome Oxidase 1 (CO1 ‘DNA barcodes’) of 28 specimens from 13 localities in 6 countries. Tatuidris are cryptic ants that inhabit the leaf litter of Neotropical forests from Mexico to French Guiana, central Brazil, and Peru. Based on the extent of the morphological variability encountered throughout this broad geographic range, T. kapasi is relegated to junior synonymy under T. tatusia. Analysis of barcodes indicated a pattern of genetic isolation by distance, suggesting the presence of a single species undergoing allopatric differentiation. The genus Tatuidris, thus, remains monotypic. Male and female reproductive castes are described for the first time.
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.
