Bibliographic record
Abstract
Abstract The fly Heleomyza serrata (Linnaeus) (Diptera: Heleomyzidae) is reported to range widely throughout the United States of America and Canada. However, in Eurasia, this species is restricted to northern regions; in central and southern Europe, H. serrata is replaced by the similar species H. captiosa (Gorodkov), which can be distinguished from H. serrata by the male genitalia. We report H. captiosa from Kentucky, United States of America, the first Nearctic record of this species. The taxonomy of Nearctic Heleomyza Fallén is discussed, and we propose to transfer three species to the genus Scoliocentra Loew: Scoliocentra (Scoliocentra) bisetata (Garrett) comb. nov., S. (Leriola Gorodkov) latens (Aldrich) comb. nov., and S. (L.) nebulosa (Coquillett) comb. nov. We recognise Anypotacta Czerny as a subgenus of Heleomyza and transfer the two Nearctic species to that genus: H. (A.) aldrichi Garrett comb. nov. and H. (A.) gillinom. nov. (new replacement name for Anypotacta czernyi Gill, 1962). Finally, we provide an updated key to Nearctic Heleomyza and morphologically similar species of Scoliocentra. Further study will be required to ascertain the range and abundance of H. captiosa in North America.

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.
