First Record of Sericomyrmex mayri for Paraguay and Increasing the Range of Distribution of 17 Ant Species in the Central Department
Bibliographic record
Abstract
Ants have been studied in Paraguay, South America, over the last two centuries, nevertheless new species can still be discovered with simple sample surveys. Most species collected in the country belong to one or few locations, therefore knowledge about species distribution is limited. A total of 2,040 ants have been collected, belonging to 7 subfamilies and representing 44 species. All of these species, except Sericomyrmex mayri, were documented for Paraguay and 17 species were first documented in the Central Department. Those 17 species are: Camponotus sanctaefidei, Crematogaster acuta, C. arata, Cyphomyrmex laevigatus, C. lectus, C. minutus, Forelius pusillus, Linepithema neotropicum, L. pulex, Mycetomoellerius fiebrigi, Nylanderia docilis, Pheidole cyrtostela, Pogonomyrmex tenuipubens, Solenopsis megergates, S.richteri, Strumigenys hindenburgi, and Wasmannia lutzi. These species belong to 12 genera and 3 subfamilies. The new recorded species is described and illustrated with photographs of the collected specimens as well as a short description of taxonomy, ecology, and distribution. A list of the new species to the Central Department is also provided. The aim of this study is to increase the knowledge of ant species in Paraguay and their distribution.

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.
