Abstract
Trichocoelina biplex sp. n. Figs 2 A, 3 C Material studied. Holotype male. CANADA, Newfoundland and Labrador, Torngat Mountains National Park, Saglek / Base Camp, 58.451°N, 62.798°W, 5 m, 9.VIII.2013, D. Whitaker (BOLD Sample ID BIOUG11125-C09, in CNC). Paratypes. CANADA, same data as holotype but 16.VIII.2013, 1 male (BOLD Sample ID BIOUG11632- G07, in CBG); same data as previous but 20.VII.2014, 3 males (BOLD Sample IDs BIOUG18960-C12, BI- OUG18960-E11 and BIOUG18962-F10, in CBG); Yukon, Ogilvie Mts. North Fork Pass, 7.VIII.1963, P.J. Skitsko, 1 male (in MZH). Description. Male. Head. Face and antenna concolorous brown, maxillary palpus pale yellowish. Eye bridge 2–3 facets wide. Face with 22–32 setae. Clypeus with 1 seta. Maxillary palpus with 3 segments, 1 st segment as long as 3 rd segment, 2 nd segment shortest; 1 st segment with 1 seta, with dorsal patch of sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 2.2x as long as wide, the neck shorter than broad, the longest setae shorter than the width of flagellomere. Thorax. Brown, setae pale. Anterior pronotum with 4–9 setae. Proepisternum with 6–9 setae. Scutellum with 3–4 longer and some short and fine setae. Wing. Fumose. Length 2.0– 2.1 mm. Width/length 0.40. Anal lobe weak. Veins distinct. c/w 0.55–0.65. R 1 /R 0.55–0.70. stM shorter than fork of M. r-m longer than bM, bM non-setose, r-m with 1–6 setae. Halter yellow. Legs. Yellow, coxal setae pale. Fore tibial organ forming a sparse patch in depression. Fore tibial spur longer than the tibial width. Abdomen. Pale brown, setae pale, rather long and fine. Hypopygium (Fig. 2 A). Brown, as abdomen. Intergonocoxal area long, basally with strongly sclerotized medial stripe, with two long, subtriangular elongated setose lobes. Gonocoxa pale brown, narrow, longer than gonostylus, medial margin basally smoothly curved, with rather long but sparse setosity. Gonostylus (Fig. 3 C) yellow, rather long, apically slightly narrowed, strongly impressed; with normal setosity, with a long apical tooth, with 6–7 megasetae at middle, megasetae slightly curved, long and slender; with 1 well-differentiated whiplash seta on ventromedial margin. Tegmen broader than long, basolaterally broadened, apically roundish, with subapical semicircular sclerotization, aedeagal teeth not detectable in the specimens studied. Aedeagal apodeme short. BIN. BOLD:ACG3979. Discussion. By the general structure of its hypopygium, Trichocoelina biplex sp. n. resembles T. vitticollis (Holmgren) but differs in having the intergonocoxal lobes distinctly separate and shorter, the tegmen more modified with basolateral shoulders and a sclerotized apical rim, the gonostylus less curved and with a shorter apical tooth, the megasetae in a less compact group, and in its darker antennal flagellomeres. See also under T. aemula. Etymology. The name is Latin, biplex, divided, referring to the distinctly separate, long intergonocoxal lobes of hypopygium.
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.
