Revision of the Nearctic species of Gimnomera Rondani (Diptera: Scathophagidae), with morphological phylogeny and DNA barcodes
Bibliographic record
Abstract
The Nearctic species of Gimnomera Rondani are revised and includes eight species, of which three are new to science (G. aquilonia sp. nov., G. cerea (Coquillett), G. cuneiventris (Zetterstedt), G. incisurata Malloch, G. subvittata (Malloch), G. terrywheeleri sp. nov., G. tibialis (Malloch), G. vockerothi sp. nov.). Gimnomera cuneiventris is newly recognized as Holarctic in distribution. Gimnomera fasciventris Malloch is removed and transferred to the genus Acerocnema, comb. nov. An additional Nearctic species is recognized but not described due to lack of male specimens. Species descriptions, diagnoses and distribution maps are presented, including images of the male terminalia as well as additional diagnostic characters. A key to the Nearctic species is also provided. A morphological cladistic analysis of 12 species reveals that the Nearctic and Palearctic species do not form separate monophyletic groups. COI mitochondrial DNA barcode sequences were obtained for eight Nearctic species of Gimnomera.
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.
