A new Mexican species of Megarthrus Curtis (Coleoptera, Staphylinidae, Proteininae)
Bibliographic record
Abstract
The genus Megarthrus Curtis with about 140 species described, is the largest of the subfamily Proteininae (Coleoptera: Staphylinidae) (Cuccodoro 2011; López-García et al. 2011). It is distributed worldwide (Cuccodoro 1999) and has an amphipolar distribution, being more diverse in Holarctic region (Newton 1985). In the tropics, the ecological requirements of Megarthrus species restrict their presence to mountain areas, showing high levels of endemism, making a taxon potentially informative for biogeographic analysis (Cuccodoro 1998). In Mexico there was only one described species: Megarthrus altivagans Bernhauer, 1929, but it is known that there are several undescribed species (Navarrete-Heredia et al. 2002). Cuccodoro (2011), recognised “eleven species from Mexico, eleven species from Costa Rica, Guatemala, Honduras, Nicaragua and Panama, and fifteen species from Bolivia, southern Brazil, Colombia, Ecuador, Peru and Venezuela”. In this paper we describe a new species of Mexican Megarthrus from the State of Jalisco.

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.
