Abstract
Pelecocera pergandei (Williston) Differential diagnosis. Pelecocera pergandei has a shiny pleuron, narrow frons, yellow face with a medial black fascia and black gena, and abdominal terga 2–4 with a yellow fascia. It differs from P. tricincta by having postpronotum black (yellow in P. tricincta) and the male has the eye margins almost parallel on level of frons (approximating each other in P. tricinta). For a full description see Williston (1884). Distribution. Single Nearctic species of this genus, occurring from south Ontario in Canada eastwards to New York, and southwards to Mississippi and Georgia in U.S.A. Material examined. USA: Maryland, Rosedale, 10.x.1986, M. Takau [1♀, USNM; USNM ENT 00035261]; Maryland, Glen Echo, 26.ix.1926, N.K. Bigelow [1♂, CNC]; Mississippi, Webster Co., The Cove, T20N, R8E, Sec. 12, 7 mi W Walthall, 19.x – 4.11.1988, T.L. Schiefer, malaise trap in mixed mesic forest ravine [1♀, USNM; USNM ENT 00035269].

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.
