New generic concepts for orphaned lineages formerly treated as part of the genus Ocyptamus Macquart, 1834 (Diptera, Syrphidae)
Bibliographic record
Abstract
The large syrphid genus Ocyptamus Macquart has been subject to scrutiny in recent years, resulting in a more narrowly defined monophyletic Ocyptamus sensu stricto. Some of the species excluded from this narrower concept of the genus are in evolutionary lineages for which generic names are available, but other species are in lineages for which generic names do not exist. The current paper presents five new genera to correct this: Fragosa gen. nov. (former Ocyptamus stenogaster group), Hypocritanus gen. nov. (former Ocyptamus fascipennis group), Maiana gen. nov. (former Ocyptamus callidus group), Nuntianus gen. nov. (former Ocyptamus lepidus group) and Victoriana gen. nov. (former Ocyptamus melanorrhinus group). In addition to the new combinations related to these new genera, Argentinomyia aenea (Williston) comb. nov., Hybobathus pola (Curran) comb. nov., H. subchalybeus (Walker) comb. nov., H. wilhelmina (Doesburg) comb. nov., and Leucopodella nasuta (Williston) comb. nov. are moved out of Ocyptamus. Ocyptamus isthmus Thompson is a jun. syn. of Callostigma panamensis Curran stat. rev. Relevant morphological characters and their taxonomic and evolutionary implications are discussed.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
