The Neotropical Orthonevra Macquart, 1829 (Diptera: Syrphidae)
Bibliographic record
Abstract
The Neotropical species of the flower fly genus Orthonevra (Diptera: Syrphidae) are revised and 12 new species are described and illustrated: Orthonevra batman sp. nov., O. cthulhu sp. nov., O. gli sp. nov., O. gouletmasnerorum sp. nov., O. hypnotica sp. nov., O. minuosetulata sp. nov., O. nebulosa sp. nov., O. neiae sp. nov., O. roseae sp. nov., O. sternolobosa sp. nov., O. theta sp. nov., and O. thompsoni sp. nov. In addition, seven species are redescribed and illustrated: O. argentina (Brèthes, 1922), O. chilensis Thompson, 1999, O. flukei (Sedman, 1964), O. gewgaw (Hull, 1941), O. neotropica (Shannon, 1925), O. quadristriata (Shannon & Aubertin, 1933) and O. shannoni (Curran, 1926), and three Nearctic (one extending into the Neotropical region) species are diagnosed: O. bellula (Williston, 1882), O. nitida (Wiedemman, 1830) and O. nitidula (Curran, 1925) (for a total of 20 species with Neotropical distribution). Lectotypes are designated for two species, Chrysogater bellulus Williston and C. nitidus Wiedemann, and C. lugubris Jaennicke (1867) is removed from Orthonevra and left incertae sedis. A dichotomous and an interactive pictorial key to these species are also presented.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
