Aleochara pseudochrysorrhoa, a new species from southern Brazil (Coleoptera: Staphylinidae: Aleocharinae), with a complete checklist of Neotropical species of the genus
Bibliographic record
Abstract
The ectoparasitoid habit of larvae and the active predatory habit of adults of Aleochara Gravenhorst, 1802 established this group as natural fly regulators and important for ecological studies, biological control programs and forensic entomology. In the current study, a new aleocharine species, Aleochara pseudochrysorrhoa sp. nov., from southern Brazil, is described and its natural history is briefly discussed. The species has a robust body, uniformly dark-brown to black with apex of abdomen rust-brown, median lobe of male with expanded bulbus, sclerites of internal sac forming complex arrangement, and female with spermatheca L-shaped. Aleochara pseudochrysorrhoa sp. nov. may be considered to be closely related to the species belonging to the lustrica group. A complete checklist of Neotropical species of Aleochara is also provided. Nomenclatural problems are also discussed. Aleochara lateralis Erichson, 1839 is a junior primary homonym of A. lateralis Heer, 1839, and is replaced by the available name Aleochara bonariensis Lynch, 1884. A new name, Aleochara newtoni nom. nov., is proposed to replace Maseochara (= Aleochara) duplicata Sharp, 1883, which is a junior secondary homonym of A. duplicata Erichson, 1839.

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.
