A new species of <i>Ataenius</i> Harold(Coleoptera: Scarabaeidae: Aphodiinae)from the southeastern United States,with a lectotype designation
Bibliographic record
Abstract
A new species of Ataenius Harold, Ataenius thomasi Schnepp and Ashman (Coleoptera: Scarabaeidae: Aphodiinae), from Florida, Georgia, and Mississippi, U.S.A. is described. The lectotype for Ataenius brevis Fall is designated. In the United States and Canada the genus Ataenius Harold (Coleoptera: Scarabaeidae: Aphodiinae) contains 46 species (Stebnicka 2007; Smith 2009). The most recent faunal review of this genus in these countries was completed by Cartwright (1974). However, several species in that paper have been moved to other genera or synonymized (Stebnicka 2007). Stebnicka and Lago (2005) provide a key and catalog to the Ataenius strigatus group. Specimens of a putative new species of Ataenius occurring in northern Florida were located in the Florida State Collection of Arthropods (FSCA). This new species is similar to Ataenius brevis Fall, but several morphological differences have been identified and are outlined in this paper. In looking for supplementary material, additional specimens of the new species were found in the Snow Entomological Museum Collection (SEMC) and United States National Museum of Natural History (USNM). After consulting the original description of A. brevis, it was discovered that no holotype was designated and that two specimens were present in the type series. Syntypes of A. brevis were borrowed to confirm the new species is morphologically distinct and a lectotype is designated to eliminate potential confusion with the new species and to fix the name to a single specimen.

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.
