Description BODY (Fig. 25). Length 1.2–1.5 mm. Head caramel-brown, paler under microtomentum, with silvery microtomentum limited to bases of interfrontal and orbital bristles, ocellar triangle, lunule, and around inner vertical bristle; gena yellow; antenna yellow-brown. Frontal width 2.5× interfrontal height. Eye height 2.5× genal height. Thorax brown. Scutum with pale grey and brown microtomentum forming two dark longitudinal stripes, lateral margins broadly yellow microtomentose, pale M-shaped microtomentose mark at level of posterior dorsocentral bristles; scutellum brown with median, dark brown microtomentose triangle. Anterior dorsocentral bristles separated by 9–10 rows of acrostichal setulae. Legs brown, mid femur apically paler, tarsi slightly paler. Male mid tibia with stout apicoventral bristle only. Wing (Fig. 41B) pattern weak. CS2 0.5 × CS3. R 2+3 broadly curved in apical half, angled at ~60° to costa; costa extending well beyond apex of R 4+5 (5–6 × costal width). M 1 indistinct beyond dmm; M 4 extended beyond dm-m; CuA+CuP long. Halter brown. MALE ABDOMEN (Fig. 26). S5 broad, deeply posteromedially desclerotized and densely long-setose posterolaterally. S6 curved with a tab-like, densely setulose, posteromedial lobe. Cercus flat, subtriangular and indistinct from epandrium, with several small setae; subepandrial sclerite indistinct but medially darkened. Anteromedial apodeme of hypandrium elongate and sinuate. Surstylus long but low, bilobed: anterior lobe larger, subrectangular, setulose on the inner ventral surface with pointed anteroventral apex, posterior lobe triangular, curved downwards and twisted inwards, with setulae along anterior margin. Postgonite short but broad, curved, evenly tapered with apex bifurcate, posterior half pale. Phallapodeme elongate, gently curved with slightly hooked apex; basiphallus flattened laterally and elongate with a slender, slightly sinuate, tapered epiphallus. Distiphallus stout, complex but largely membranous, basal half with a pair of ovoid upper sclerites, apex supported by pair of curved dorsolateral sclerites, lower surface almost entirely papillate. FEMALE ABDOMEN (Fig. 27). T6 and T7 rectangular, desclerotized anteromedially (T7 divided completely) and long-setose along posterior margin; T8 broad and entire, laterally expanded posteriorly with long lateral setae. Epiproct membranous, indistinct. S6 rectangular; S7 broadly emarginate and long-setose along posterior margin; S8 subtriangular, anteriorly projecting into emargination of S7, with V-shaped row of setae. Hypoproct reduced, rectangular, largely membranous except for a sclerotized, setulose medial part. Spermathecae stout, subcylindrical, slightly wider at base, lightly grooved with deep invaginations at both ends, each invagination with a small central projection, stem very short and membranous. Remarks Parapterogramma peckorum sp. nov. is externally similar to Pa. matau sp. nov. and Pa. tokotaai sp. nov. Males of Pa. peckorum differ from those of Pa. tokotaai by their mid tibial chaetotaxy, including a weak apicoventral bristle and a conspicuous row of stout anteroventral seta; both sexes differ from Pa. matau in having a distinct extension of M 4 beyond dm-m.

Not 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.
