Abstract
Bradysia falciceps sp. nov. urn:lsid:zoobank.org:act: 60FA7B62-2FFA-43FE-A5A2-5AC02CF29B13 Fig. 4 A–B Diagnosis Small-sized Bradysia. Brown. Maxillary palpus with 3 segments, segment 1 with shallow sensory area. Wing length 1.5–1.7 mm, veins indistinct. Gonostylus narrow, mesially impressed, with apical tooth and 5–6 megasetae in one group. Etymology The name is derived from the Latin words falx (scythe) and - ceps (of the head), referring to the curved apical tooth of the gonostylus of the species. Material examined Holotype FINLAND: ♂, Lapponia inariensis, Utsjoki, tundra, Malaise trap, 14 Aug. 2000, Fatouros, MZH. Paratypes FINLAND: Same data as holotype, 1 ♂, PKHH 3368; Regio aboensis, Turku, Pomponrahka (Grid 6719377:3240217), open bog, Malaise trap, 1 Aug.–28 Sep. 2011, J. Salmela, 1 ♂, MZH. CANADA: Ontario, Sudbury Co., Chapleau, Superior Forest, mature (99 years old) stand composed of 90% Pinus banksiana and 10% P. mariana with an understory shrub layer of Vaccinium, very wet, with considerable bryophyte coverage, photoeclector on pine log, 23 Jun.–8 Jul. 2013, R. Deady & T. Work, 3 ♂♂, PRDM; same data but 7–22 Jul. 2013, 1 ♂, MZH. Description (male) HEAD. Brown, antennal flagellomeres 1–2 yellow, scapus, pedicellus and flagellomeres 3–14 unicolorous pale brown; maxillary palpus very pale brown. Eye bridge 3 facets wide. Face with 15–21 scattered longer and shorter setae. Clypeus with 1–2 setae. Maxillary palpus with 3 segments; segment 3 longer than segment 1, segment 2 shortest; segment 1 with 1–2 setae, with small shallow dorsal sensory area; surface of antennal flagellomeres smooth, body of flagellomere 4 1.85–2.3× as long as wide, neck shorter than broad, longest setae as long as width of flagellomere. THORAX. Brown, setae pale. Anterior pronotum with 4–7 setae. Episternum 1 with 8–9 setae. Scutum with long dorsocentrals, with some longer and shorter laterals, scutellum with 4 longer and some short setae. WING. Hyalinous. Length 1.5–1.7 mm. Width/length 0.45–0.50. Veins indistinct. R1/R 0.60–0.65. c/ w 0.75 –0.85. r-m and bM subequal in length. r-m with 1–2 setae, bM non-setose. LEGS. Yellow. Coxal setae pale. Front tibial organ with pale vestiture forming short row. Front tibial spur longer than tibial width. Claws without teeth. ABDOMEN. Pale brown, setae pale and fine. HYPOPYGIUM (Fig. 4 A–B). Brown, concolorous with abdomen. GONOCOXA. Narrow, longer than gonostylus, mesial margin with normal setosity. GONOSTYLUS. Narrow, evenly straight, with shallow lateral notch at apical fourth, with mesial side impressed at all its length; with dense apical setosity, with strong curved apical tooth-like megaseta, with 5–6 subapical megasetae, megasetae sharp, in single group. Tegmen conical, weakly sclerotized, with area of aedeagal teeth. Aedeagal apodeme long. Remarks Bradysia falciceps sp. nov. belongs to the Bradysia praecox group and is most similar to B. nitidicollis (Meigen, 1818), B. iridipennis (Zetterstedt, 1938) and B. quercina Menzel & Köhler, 2014 by sharing a strong apical tooth at the dorsoapical part of the gonostylus (see Köhler et al. 2014). Bradysia falciceps sp. nov. can be distinguished from all other species of the B. praecox group in having pale basal antennal flagellomeres with dark necks.

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.
