Family groups of Diopsoidea and Nerioidea (Diptera: Schizophora)—Definition, history and relationships
Bibliographic record
Abstract
The Acalyptratae are a diverse, heterogenous assemblage of dozens of families of "higher flies" in the Schizophora (Diptera). There are ten acalyptrate superfamilies, two of which are reviewed and redefined here at the family-group level: Diopsoidea and Nerioidea. The superfamily Diopsoidea includes seven families: Diopsidae (two subfamilies and two tribes), Gobryidae, Megamerinidae, Nothybidae, Psilidae (three subfamilies), Somatiidae and Syringogastridae. The superfamily Nerioidea also includes seven families: Cypselosomatidae, Fergusoninidae, Micropezidae (five subfamilies), Neriidae, Pseudopomyzidae, Tanypezidae and Strongylophthalmyiidae. All 14 families are redescribed, figured and keyed, including notes on subordinate family-level groups. Homologies for external and genitalic characters are established, and the superfamilies and their family-level groups are discussed. A morphological phylogenetic analysis is provided, including representatives from all family-level groups in both ingroup superfamilies, as well as twelve outgroup taxa from five other acalyptrate superfamilies. Both superfamilies were supported as monophyletic, although both the Diopsoidea and its basal branches were supported by highly homoplasious characters and are here only tentatively accepted; a relationship between Diopsidae, Syringogastridae and Megamerinidae is strongly supported. Nerioidea is a well-defined group divided into three lineages, including one containing Pseudopomyzidae, Cypselosomatidae and Fergusoninidae, the latter of which was previously considered to be related to the family Agromyzidae (Opomyzoidea). Diopsoidea and Nerioidea were not found to be related.

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.
