Abstract
This dataset contains the digitized treatments in Plazi based on the original journal article Ware, Jessica L., Hulick, Carl Patrick, Newton, Lacie, Kohli, Manpreet K., Tolman, Ethan R., Goodman, Aaron, Beatty, Christopher D., Guralnick, Rob, Abbott, John C., Frandsen, Paul B., Soto-Centeno, J. Angel, Bybee, Seth (2025): Bringing Shadowdragons to light: Neurocordulia (Anisoptera: Corduliidae) systematics. International Journal of Odonatology 28: 1-15, DOI: 10.48156/1388.2025.1917307, URL: https://doi.org/10.48156/1388.2025.1917307Abstract. Neurocordulia, commonly called shadowdragons, are crepuscular dragonflies, flying mainly at dusk. The genus comprises seven species, which occur across the eastern part of Canada and the United States. Here, we used targeted enrichment probes to sequence ~1000 loci for all specimens of each species, allowing for the first phylogenetic assessment of the genus. Additionally, we collected individuals of N. yamaskanensis from a population in Ontario, Canada, and used whole genome resequencing to estimate population structure. Beyond broadly reconstructing the phylogeny of Neurocordulia, we provided a comprehensive bibliography review of past research on the genus, a key to the species, and distribution models for each species.

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 it
