Revision of the new world fauna of Mesembrina Meigen (Diptera: Muscidae) with the description of a new neotropical species
Bibliographic record
Abstract
The large striking flies of the genus Mesembrina are typically found in boreal forest and at high elevations throughout the Northern Hemisphere. While it is known that most species are decomposers of ungulate dung, biological and taxonomic information on the New World fauna of Mesembrina is mostly out of date or unreliable. Consequently, the Nearctic taxa have been revised, resulting in the new synonymy of Mesembrina solitaria (Knab) with Mesembrina decipiens Loew, making M. decipiens the only species of the genus with a confirmed Holarctic distribution. Mesembrina latreillii Robineau-Desvoidy, contrary to previous indications, may be restricted to the Nearctic Region. The first Neotropical member of the genus, Mesembrina nigribasis sp. nov. is described. To place the New World fauna in context, a key to the world species of Mesembrina is provided. This key includes a species designated by Hennig as “resplendens subspecies” from the Palaearctic, which is a distinct but undescribed species.

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.
