The female abdomen and genitalia of Syrphidae (Diptera)
Bibliographic record
Abstract
The female abdomen of Syrphidae was studied based on a sample from all currently recognized tribes, except Spheginobacchini. All characters found were compared with previous literature on Syrphidae female abdomen and some were proposed as diagnostic for the taxa. The condition of the postabdomen distinguishes Pipizinae from the Syrphinae. Presence of sclerotized areas on the intersegmental membrane appears characteristic of the Rhingiini. Tergite and sternite 6 had unique characteristics only found in Cerioidini, and sternite 8 had a condition only found in Cerioidini and Callicerini. Notiocheilosia (Callicerini) seems more similar to Nausigaster (Eumerini). Characters present in both the Eristalini and Sericomyiini are presented. The condition of the epiproct, and of its apodemes, proved diagnostic for Microdontini, Volucellini and some Syrphini plus the Paragini. Bacchini sensu lato and Toxomerini were also distinct. The Milesiini still need to be sampled more broadly to ascertain about its relationships with other tribes and within.

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.
