A revision of the concept of Mago O. Pickard-Cambridge, 1882, and proposal of a new genus (Araneae: Salticidae: Amycini)
Bibliographic record
Abstract
In this paper we redescribe the type species of Mago O. Pickard-Cambridge, M. intentus O. Pickard-Cambridge, and describe Mago brimodes Ruiz Maddison sp. nov. from Ecuador. Based on both morphological features and the 16SND1 gene region, we concluded that the larger spiders traditionally identified as Mago, such as Mago acutidens Simon and related species, are not closely related to the small dark M. intentus (type species) and M. brimodes. Matinta Ruiz Maddison gen. nov. is therefore proposed to hold most species previously included in Mago. The following species are transferred from Mago to the new genus: Matinta acutidens (Simon, 1900) comb. nov. (type species), Matinta apophysis (Costa Ruiz, 2017) comb. nov., Matinta balbina (Patello Ruiz, 2014) comb. nov., Matinta chickeringi (Caporiacco, 1954) comb. nov., Matinta delicata (Patello Ruiz, 2014) comb. nov., Matinta fasciata (Mello-Leitão, 1940) comb. nov., Matinta fonsecai (Soares Camargo, 1948) comb. nov., Matinta furcata (Costa Ruiz, 2017) comb. nov., Matinta jurutiensis (Patello Ruiz, 2014) comb. nov., Matinta longidens (Simon, 1900) comb. nov., Matinta mimica (Costa Ruiz, 2017) comb. nov., Matinta opiparis (Simon, 1900) comb. nov., Matinta pardo (Costa Ruiz, 2017) comb. nov., Matinta procax (Simon, 1900) comb. nov., Matinta saperda (Simon, 1900) comb. nov., Matinta silvae (Crane, 1943) comb. nov., Matinta similis (Patello Ruiz, 2014) comb. nov., Matinta steindachneri (Taczanowski, 1878) comb. nov. and Matinta vicana (Simon, 1900) comb. nov. Mago dentichelis Crane, 1949 is transferred to Noegus Simon.

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.
