Abstract
Oreiscelio megadontus Talamas, sp. n. urn:lsid:zoobank.org:act: AAFFD025-58DB-480A-84E7-013392F69E90 urn:lsid:biosci.ohio-state.edu:osuc_concepts:225544 Figures 79-84; Morphbank 39 Description. General: Body length of female: 4.1-4.1 mm (n=4.1). Body color: black. Antenna: Color of antennae in female: A1–A6 yellow; A7–A12 dark brown to black. Seta on pedicel of antenna in female: present, reaching past apex of A3. Head: Color of setae on the head: yellow. Sculpture of dorsal frons between frontal carina and median ocellus: coarsely foveate. Preocellar pit in females: present as a distinct pit. Transverse rugae at vertex: present. Sculpture of posterior vertex: coarsely foveate. Sculpture of occipital rim: areolate. Interantennal process: simple. Number of anteriorly projecting setae on anteclypeus: 8. Color of mandibles in female: yellow throughout with teeth brown. Mandibular teeth in female: ventral tooth at least twice as long and wide at base than dorsal tooth. Sculpture of ventral gena anterior to genal carina: row of shallow areolae with reduced ridges between cells. Sculpture of ventral gena posterior to genal carina: mostly smooth, with sparse small punctures. Shape of anteclypeus: striplike, straight to slightly convex. Legs: Color of legs: coxae brown, legs otherwise yellow. Mesosoma: Sculpture of dorsal pronotum: areolate. Color of setae on the dorsal mesosoma: yellow. Sculpture of medial mesoscutum: areolate, with pronounced longitudinal ridges. Sculpture of lateral mesoscutum: with small patch of smoother sculpture, formed by fusion of sculptural ridges, smooth patch not extending to scutoscutellar sulcus. Notaulus in female: absent. Parapsidal line: delimited. Sculpture of scutellum: areolate. Median furrow on scutellum: absent. Posterior margin of scutellum: emarginate. Outer projection of the propodeum: present as distinct corner or posteriorly projecting spine. Posterior margin of propodeal shelf between inner and outer propodeal projections in female: concave. Sculpture of ventral pronotum: foveate reticulate, becoming smooth at anterolateral corner. Anterior pronotal pit: small. Pronotal cervical sulcus: well defined by contiguous punctures. Mesepimeral sulcus: indicated by dorsoventral line of foveae. Sculpture of femoral depression in female: smooth throughout. Mesopleural carina: indicated by one or two rows of punctures. Sculpture of ventral mesepisternum: with smooth area surrounded by small foveae. Pilosity of metapleural triangle in female: present as many short fine white setae. Sculpture of ventral area of metapleuron: smooth. Metasoma: Submarginal ridge on T1: partially fused with marginal carina. Sublateral carina on T2: percurrent. Sculpture of T2–T3: reticulate rugose. Sculpture of T4: longitudinally strigose. Sculpure of T5: longitudinally strigose. Shape of subapical T 6 in female in dorsal view: short, width along anterior margin at least three times the length. Longitudinal medial keel on S1: absent. Sculpture of medial S 2 in female: punctate reticulate. Sculpture of medial S 3 in female: effaced to smooth. Sculpture of medial S 4 in female: effaced to smooth. Sculpture of medial S 5 in female: reticulate rugose. Sculpture of lateral S 3 in female: foveolate. Sculpture of lateral S 4 in female: foveolate. Sculpture of lateral S 5 in female: reticulate rugose. Sculpture of marginal depression of S 2 in female: smooth. Sculpture of marginal depression of S 3 in female: smooth. Sculpture of marginal depression of S 4 in female: rugulose. Sculpture of marginal depression of S 5 in female: rugulose. Apical spine on S 6 in female: extending beyond apex of T6 and visible in dorsal view. Diagnosis. Oreiscelio megadontus is the largest known species of Oreiscelio. Oreiscelio scapularis is comparable in length but is more slender. It is a relatively dissimilar species and may be identified by the combination of the much larger mandibular tooth (Fig. 83), the emarginate posterior margin of the propodeal shelf between inner and outer propodeal projections (Fig. 84), and the bright yellow legs (Fig. 79). Etymology. The epithet megadontus refers to the large size of the ventral mandibular tooth in this species. Link to distribution map. 40 Material examined.

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.
