The brown copper moth, Tridentaforma browncopper: DNA barcoding reveals a second species in the family Tridentaformidae (Lepidoptera, Adeloidea)
Bibliographic record
Abstract
A biodiversity monitoring program in south-central British Columbia, Canada, at sites on traditional nłeʔképmx territory near the Highland Valley Copper mine, collected many specimens of an unknown moth. DNA barcode analysis revealed its affinity but deep divergence (14.3%) from Tridentaforma fuscoleuca (Braun, 1923), the only species in the family Tridentaformidae. The new species was assigned to the BIN (Barcode Index Number) BOLD:AFK8960. Morphological study confirmed its placement in this family but revealed marked genitalic differences from T. fuscoleuca . Given its genetic and morphological divergence, we describe Tridentaforma browncopper Monckton & Levesque-Beaudin, sp. nov. The scientific name is a translation of the name, skʷúnkʷl̓itkax̣n̓I, chosen by nłeʔképmx Elders and Knowledge Keepers, which means “brown copper moth”. Its discovery and naming reflect an effective collaboration among biodiversity scientists, industry representatives, and Indigenous communities. It also demonstrates how DNA barcoding can facilitate species descriptions without requiring taxonomists with specialist expertise in the group under investigation.

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.
