Abstract
Stenus perpastus nov.sp. (Figs 3, 22, 54) Type material: Holotype () and 3, 2 - paratypes: Taiwan: Kaohsiung Hsien: Kuanshan, Kuanshanshing Hut, 2950m, 18.IV.1992, A. Smetana (T 93). Paratypes: 1: same as HT, 3020m, 18.IV.1992, idem (T 90); 3, 6: Road above Tona Forest Station, km 16-17, 1700-1800, 28.IV.1998, idem (T 190); 3, 1: ibidem (Fork), 1850m, 29.IV.1998, idem (T 191); 1: Pingtung Hsien: Peitawushan trail at 1500m, 1.V.1992, idem (T 110).- HT and PTT in cS (Ottawa), PTT also in cP and cT. Description: Apterous, black, elytra dark brown (can be even lighter), slightly shiny, punctation of frons coarse and dense, that of pronotum and elytra, very coarse, very dense, slightly coalescent, punctation of abdomen moderately coarse and dense anteriorly, fine and dense posteriorly. Maxillary palpi reddish yellow. Base of antennae yellowish brown, club infuscate. Legs yellowish brown. Length: 2.5-3.1mm (forebody: 1.4-1.5mm). PM of the HT: HW: 30; DE: 15; PW: 22.7; PL: 22.7; EW: 28; EL: 23; SL: 17.5. Male: Metasternum shallowly impressed, coarsely and densely punctate. Sternites 3-6 simple, sternite 6 with a horse-shoe like impression in posterior two thirds, which is very finely and very densely punctate and pubescent, posterior margin very shallowly emarginate, sternite 7 with a long an broad oval median impression, punctation as previous, posterior margin with a moderately shallow emargination.. Sternite 8 (fig. 3) with a narrow apical emargination, which is as deep as one sixth of the sternite’s length. Sternite 9 with long apicolateral teeth. Aedeagus (fig. 22), median lobe truncate at apex, expulsion hooks connected medially; parameres very long, broad, with 13-15 setae medially. Female: Sternite 8 obliquely triangular at posterior margin, rounded medially. Valvifer with a long apicolateral tooth. Spermatheca (fig. 54). Head slightly broader than elytra, frons about as in S. perpauper. Antennae and pronotum as in S. perpauper, but the punctation of the pronotum coarser and more confluent, diameter of punctures nearly as large as apical cross section of antennal segment 2. Elytra about as in the compared species, but with distinct longitudinal impressions in lateral half and near suture, the punctation slightly coarser, largest punctures as large as medial cross section of antennal segment 2. Abdomen about as in the compared species, the punctation slightly coarser. Microsculpture of the exosceleton very dense and distinct, especially that of the elytra. Comparative notes: This new species belongs also to the S. cephalotes - group and may be distinguished from its close relatives by the sexual characters. Etymology: Because this species is slightly more robust than f. e. S. perpauper I name it " perpastus " (Lat. =well fed).

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.
