Description BODY (Fig. 20). Length 1.2–1.5 mm. Head dark brown 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 1.5× interfrontal height. Eye height 2.5× genal height. Thorax brown. Scutum with grey and brown microtomentum in presutural half forming two dark longitudinal stripes, lateral margins broadly dark brown, posterior margin with a pair of dark brown microtomentose marks; scutellum brown with median, dark brown microtomentose triangle. Anterior dorsocentral bristles separated by 9–10 rows of acrostichal setulae. Legs brown, mid and hind femora apically pale, tarsi and fore tibia paler. Male mid tibia with long apicoventral bristle and a row of ventral setae along apical two-thirds. Wing (Fig. 40H) 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 (6–7× costal width). M 1 and M 4 both lacking (thus cell dm with rounded corners); CuA+CuP long. Halter whitish. MALE ABDOMEN (Fig. 21). S5 broad with a very large, posteromedial emargination, and long, dense posterolateral setae. S6 with an elongate, strongly sinuate ventrolateral apodeme extending underneath the medial part of S5, apex with a dark dorsal knob; S7 broad. Epandrium small, wedge-shaped and sparsely long-setose laterally; cercus flat, rectangular, ventrally projecting as a small triangular lobe, with a medial patch of setulae surrounding a very large seta; subepandrial sclerite rectangular, indistinct but medially darkened. Surstylus long but low, bilobed: anterior lobe larger, subrectangular, with three long ventral setae and several setulae along posteroventral margin, posterior lobe subrectangular with preapical constriction, resembling an axe head, apex with an anterior seta and several setulae. Postgonite elongate, sinuate and strongly bent about midlength, apex bifurcate with a flattened, truncate outer lobe and a tapered inner lobe. Phallapodeme elongate, slightly sinuate with distinctly bent apex; basiphallus wedge-shaped with a slender, sinuate, tapered epiphallus. Distiphallus stout, largely membranous, basal half with a broad, Y-shaped upper sclerite, apex with large lateral flaps supported by lateral extensions of the basal sclerite, lower surface almost entirely papillate. FEMALE ABDOMEN (Fig. 22). T6 and T7 rectangular, slightly desclerotized anteromedially and long-setose along posterior margin; T8 desclerotized medially and split into two large lateral plates with long lateral setae. Epiproct membranous, indistinct. S6 rectangular, desclerotized posteromedially; S7 broadly emarginate anteriorly and posteriorly and long-setose along posterior margin; S8 subtriangular, anteriorly projecting slightly into emargination of S7, with a V-shaped row of longer setae and a transverse row of small setae. Hypoproct reduced, rectangular, largely membranous with four small setae. Spermathecae stout, subcylindrical, slightly wider at base, lightly grooved with deep invaginations on both ends, stem very short and membranous. Remarks Parapterogramma matau sp. nov. differs from the externally similar Pa. peckorum sp. nov. and Pa. tokotaai sp. nov. in lacking a distinct M 4 beyond dm-m. It is generally larger and darker than the latter species and further differs by genitalic characters including the axe-shaped posterior surstylar lobe and truncate postgonite.

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.
