New species in the<i>Lasioglossum petrellum</i>species group identified through an integrative taxonomic approach
Bibliographic record
Abstract
Abstract By means of an integrative taxonomic approach using morphology and DNA barcodes, multiple cryptic species within Lasioglossum ( Dialictus ) petrellum (Cockerell) (Hymenoptera: Halictidae) were discovered. Analysis of DNA barcode sequence data from across the supposed range of L. petrellum revealed distinct genetic differences that correlate with patterns of morphological variation and geographical distribution. The most morphologically distinct pair of species had the smallest DNA-barcode gap. The taxonomic limits of L. petrellum are revised and four new species are described and illustrated: L. ( D. ) tuolumnense sp. nov. , L. ( D. ) griswoldi sp. nov. L. ( D. ) droegei sp. nov. , and L. ( D. ) viridipetrellum sp. nov. A key to species of the “ L. petrellum ” group is provided.

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.
