Yanega" (1 ♂: D Yanega, ROME145008-UFMG). Description. FEMALE (Fig. 7). Length: 2.9 mm. Color: head iridescent greenish blue or violet (Fig. 7F); mesosoma and metasoma iridescent greenish blue or violet; clypeus ventral margin black; antenna with scape and pedicel weakly iridescent greenish blue or violet, flagellum dark brown or black, lighter ventrad and distad (Fig. 7A). Head (Fig. 7E–I): in dorsal view weakly transverse, width less than twice length, HW/HL about 1.9. Frontal carina: in anterior view straight to weakly sinuate below midlevel of eye; in dorsal view gradually narrowed V shape around median ocellus, FC/MOD about 1.3 (Fig. 7E); distance from lateral ocellus short, FCLO/LOD about 0.7 (Fig. 7E). Scrobal cavity (Fig. 7G): in anterior view narrow, SW/HW about 0.4. Ocelli (Fig. 7E): a line between anterior margin of lateral ocelli reaching anterior margin of median ocellus. POL/OOL about 1.6. Ocellar ratios LOD: POL: OOL: LOL: 1, about 2.6, 1.7, 0.8. Vertex: smooth, without large piliferous punctures. Parascrobal area: in lateral view abruptly narrowed slightly below mid-eye height, about 0.4 EH above lower eye margin (Fig. 7I); width narrow, PSW/EL about 0.3; sculpture smooth, without large piliferous punctures. Gena: with wide and long smooth area along outer eye margin, striate behind. Malar space: MSL/EH about 0.2. Lower face: with setae sparse laterad torulus, and sparse below. Clypeus (Fig. 7H): CW/ CH about 1.4; ventral margin concave; setae evenly distributed. Mesosoma (Fig. 7B–D): Lateral panel of pronotum: slightly narrower than prepectus, LPP/PPT about 0.7; without flange or with small, rounded flange below level of mesothoracic spiracle in posterior oblique view (Fig. 7C). Mesofemoral depression: smooth. Mesoscutum: punctures angulate, with narrow and weakly coriarious interspaces (Fig. 7B); lateral lobe smooth along notaulus; parascutal carina broadly curved, acuminate. Mesoscutellum: apex with inner margins gradually diverging; punctures angulate, with narrow and weakly coriarious interspaces. Axilla (Fig. 7D): in lateral view imbricate dorsad, and carinate ventrad. Axillula: smooth dorsad. Fore wing: stigma small, about 2.0× as wide as postmarginal vein. MALE (Fig. 8). Length: 3.1 mm. As in female, except: Color: vertex and mesonotum black. Scape (Fig. 8G): pits sparse, covering about 0.2× scape length. Etymology. The specific epithet is a reference to Minas Gerais, Brazil, where both specimens were collected. Diagnosis. Perilampus minasgerais can be recognized by a parascrobal area that is abruptly narrowed slightly below the midlevel of the eye (Figs 7I. 8E), a narrow frontal carina around the median ocellus (Figs 7E, 8B) and a male scape with a short, pitted area (about 0.2× scape length, Fig. 8G). Distribution. Neotropical: Brazil (Minas Gerais). Host association. Perilampus minasgerais is a hyperparasitoid, parasitizing dipteran parasitoids of Lepidoptera. Hosts: Tachinidae (Diptera) from Actinote parapheles Jordan (Nymphalidae) on Vernonia polyanthes Less (Asteraceae). Remarks. Perilampus minasgerais is the only species within the P. carolinensis clade with a narrow frontal carina around the median ocellus (Figs 7E, 8B cf. Figs 3E, 4B, 5E, 6B). The short, pitted area on the male scape of P. minasgerais is similar to that of P. cabecar, suggesting their sister relationship.

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.
