Abstract
Leuctra tenella Provancher 1878 Broad-lobed Needlefly http://lsid.speciesfile.org/urn:lsid: Plecoptera.specie sfile.org:TaxonName:460049 (Figs. 19–22) Leuctra tenella Provancher 1878:126. No type designation, vicinity of Quebec City Leuctra tenuis Provancher 1876:218. Not L. tenuis Pictet Leuctra hamula Claassen 1923:261. Syn. Ricker 1952 Leuctra hamula: Needham and Claassen 1925:229 Leuctra (Leuctra) tenella: Ricker 1952:171. Lectotype ♂ designated. Leuctra tenella: Illies 1966:109 Male. The 7th abdominal dorsal process bears a simple, broadly-subtriangular lobe (Fig. 19); subtle anterolateral lobes present on some specimens. The specilla are broad basally, overall shape subtriangular and bearing prominent, laterallydirected tubercles distally (Figs. 20–22). The subanal lobes are subequal in length to the specilla; near uniformly-narrow through length, tapering little but recurved anteriorly in the distal half, especially at tips (Figs. 21–22).

USA: CT, MA, MD, ME, MN, NJ, NY, OH, PA, WI, WV (DeWalt et al. 2015), NC, NH, VA, VT (new state records). Remarks. The dorsal abdominal process of this species is most similar to L. carolinensis. The specilla of L. tenella are distally truncate (Figs. 21– 22) compared to the distally-subtriangular tips of L. carolinensis (Figs. 4, 7, 9). The subanal lobes of L. tenella are sharply-recurved at the tips (Figs. 21–22), contrasting with the gradually-recurved lobes in the distal half on L. carolinensis (Figs. 4, 6‒9).

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.
