Grootaert, RBINS), 1 female, Chek Jawa, 2.XII.2003 (sample 23096, leg. P. Grootaert, ZRC). Diagnosis: Basal antennal segment pale yellowish; second segment brown; third segment almost black. Palp yellow, with white hairs. Mesonotum and scutellum black in groundcolour, covered with a thick greybrown dusting; bristles black. Abdomen with all tergites black (including first tergite), covered with black hairs and bristles. Tip of hypandrium indented. Description. Male: Body length 1.88–2.13 mm, wing length 2.13–2.25 mm. Head. Frons, face and occiput dark brown in groundcolour, densely covered by a greybrown dusting. Large bristles black. Palp yellow with yellow bristles. Antenna (Fig. 1) with basal segment yellow, second segment brownish, third segment brownishblack. Arista black. Thorax brownish black in groundcolour, covered with a thick browngreyish dusting. Humeri (postpronotal lobes), suture between notopleural depression and mesopleura yellowish brown. All bristles on mesonotum black. Legs yellow, but posterior four coxae pale brown and tarsomeres 4 and 5 contrastingly brown. Most hairs and bristles black, but fore coxa densely set with pale hairs and ventral bristles on fore femur also pale. Fore femur with anteroventral row of 7 short spinelike bristles in apical half; ventrally densely set with yellowish bristles being about half as long as femur is wide; posteriorly in apical half a row of fine bristles about half as long as femur. Fore tibia with row of small ventral spinelike bristles. Mid tibia with anterodorsal and posterodorsal bristle on basal quarter and distinct ventral preapical. No other distinct bristling on the legs. Wing with brownishgrey membrane, veins pale brown. Halter white. Abdomen with all segments black in groundcolour and covered with dense grey dusting. All bristles on tergites black, bristles on sternites pale. Genitalia as in Figs 8–11. Cerci straplike, pale yellowish. Hypandrium and extension of sternite 5 shining black. Tip of hypandrium indented, the dorsal tip with a small notch (2 notches in specimens from Pulau Tioman). Female Body length 2.13–2.25 mm, wing length 2.13–2.40 mm. Identical to male. Fore femur without ventral bristles. Tergite 10 with 10–11 spines on each hemitergite (acanthophorite) (Figs 3, 4). Derivatio nominis: the species is given the name nigra (Latin., niger: black) because all tergites are black. Distribution: Singapore: Strait of Singapore; Malaysia: South China Sea; Brunei: South China Sea. Phenology: Adults are present throughout the year in suitable habitat.

How this classification was reachedexpand
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.
