Zubryi, 5 males (1 in MZH, 1 in NHMO, 2 in SDEI, 1 in ZIN). Description. Male. Head. Face and antenna concolorous brown, maxillary palpus pale yellowish. Eye bridge 2–3 facets wide. Face with 13–20 fine setae. Clypeus with 2–5 setae. Maxillary palpus with 3 segments, 1 st segment longer or shorter than 3 rd segment, 2 nd segment shortest; 1 st segment with 1–2 setae, with a dorsal patch of sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 1.7–2.25x as long as wide, the neck shorter than broad, the longest setae slightly shorter than the width of flagellomere. Thorax. Brown, setae pale. Anterior pronotum with 2–6 setae. Proepisternum with 3–10 setae. Scutellum with 4 longer and some short and fine setae. Wing. Fumose. Length 1.9–2.1 mm. Width/length 0.40–0.45. Anal lobe weak. Veins distinct. c/w 0.60–0.65. R 1 /R 0.60–0.85. stM and fork of M subequal in length. r-m and bM of variable length, bM non-setose, r-m with 2–4 setae or non-setose. Halter yellow. Legs. Yellow, coxal setae pale. Fore tibial organ forming a small patch of dark strong setae in depression. Fore tibial spur slightly longer than the tibial width. Abdomen. Pale brown, setae pale, moderately long. Hypopygium (Fig. 15 B). Brown, as abdomen. Intergonocoxal area long, basally with strongly sclerotized medial stripe, with large subtriangular lobe with setae at margin. Gonocoxa broad, longer than gonostylus, medial margin basally strongly curved, with long sparse setosity. Gonostylus (Fig. 16 D) long, apically narrowed, strongly impressed; with short setosity, with a long apical tooth, with 6–7 medial megasetae in dorsal and ventral groups, megasetae long and slender, directed slightly differently in both groups; with 1 well-differentiated whiplash seta on ventromedial margin. Tegmen conical, apically and laterally straight or slightly curved, weakly sclerotized, with an indistinct area of minute aedeagal teeth. Aedeagal apodeme long. BIN. BOLD:AAM9263. Discussion. In having a long intergonocoxal lobe of hypopygium and 6–7 medial megasetae on the gonostylus, Trichocoelina tecta sp. n. resembles T. vitticollis (Rübsaamen) but differs in the intergonocoxal lobe being setose only on its margins, not on its ventral side, in its conical tegmen, not apically roundish, and in having the gonostylar megasetae in groups pointed at two directions, not all in a row pointing in one direction. Etymology. The name is Latin, tecta, covered, referring to the ventromedial part of the gonostylus covering almost completely the medial megasetae.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
