Abstract
Deltorhinum bilobatum sp. nov. (Figs. 8–9, 21–22) Diagnosis. Differs from all other species in the genus by the bilobate pronotal anterior edge combined with the simply convex surface behind anterior depression on each side of midline. Description. Holotype male: Body and legs black. Clypeus moderately upturned medially; median projection feebly emarginate medially; marginal bead unmodified, weakly defined laterally. Gena bluntly angular laterally. Frontal carina distinctly arcuate in dorsal view, median portion higher than lateral portions. Vertex minutely punctate. Pronotal surface minutely punctate, puncture large and weakly defined on anterior transverse depression and along longitudinal sulcus; median longitudinal sulcus wide and deeply impressed throughout; pronotal anterior edge bilobate medially, lobate portion preceded by a transverse leveled surface, surface gradually rounded behind depression, lacking small depressed area on each side of midline. Pronotal basal surface smooth on most of width along posterior edge, a few weakly defined larger punctures on median fifth. Elytral surface minutely punctate; striae fine and sharply defined, more deeply impressed on apical declivity, punctures transversal and encroaching on interstriae. Elytral epipleuron unmodified, hidden in dorsal view. Protibia with punctures more or less set on a single oblique row on dorsal surface. Profemur sharply carinate anteriorly. Mesofemora and metafemora simply convex ventrally. Mesotarsi and metatarsi with first tarsomere slightly longer than width at apex. Pygidial surface finely punctate throughout; basal sulcus narrowly rugose; apical marginal bead sharply defined internally. Measurements (3 specimens): body length: 9.0– 9.5 mm.

DATABASE, WSD00008018 / Holotype 3, Deltorhinum bilobatum sp. nov. F. Génier, 2010. Aedeagus extracted. Material examined (13, 2ƤƤ): BRAZIL: MATO GROSSO, Uirapuru, (14°0'56''S, 59°22'4''W), ii.2003, coll. A. Foucart - 1Ƥ (paratype) (CEMT); Utiariti, Rio Papagaio, (13°1'51''S, 58°17'3''W), 22–31.x.1966, coll.

S.R. Rodrigues - 1Ƥ (paratype) (CEMT). Etymology. Bilobatum, a Latin adjective in apposition referring to the pronotal bilobate anterior edge. Natural history. Unknown. Variation. As for D. armatum, the only variation resides in size and the female having coarser pronotal punctures. Remark. The holotype was killed in formalin and the internal sac could not be extracted and prepared for illustration. This is the only known male 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.
