A.B.); Lavrentiy Bay (E Chukotka, 3 ex., coll. A.B.) Mountains of boreal zone: Komi Republic (Middle Ural Mts, Pechora River, 2 ex., coll. M.P.); Bol'shoy On River (Khakasiya, W Sayan, 1 ex., coll. S.Bugrov); Goudjekit River (NW Buryatia, 16 ex., coll. M.P. and A.G.); Gremyachaya Brook (NW Buryatia, Barguzin Range, 2 ex., coll. M.P. and A.G.); Slyudyanka River and Serdtse Lake (Irkutskaya Region, W Khamar-Daban Range, 9 ex., coll. M.P. and V.Kadnikov); Ola River (Magadan Region, 1 ex., coll. A.B.). Description of populations from Buryatia and Irkutskaya Region. Ground colour yellowish or greenish. Dorsum much darker, pigmentation more developed on thorax and anterior half of abdomen. Antennae 1.4–2.4 (mostly 1.6–2.1) as long as head diagonal. Frontoclypeal field without a distinct "moustache", chaetae stronger over labral base. Chaetae of body subequal, short and fine. Ventral tube with more than 20 posterior chaetae, 11– 18+11–18 lateral, and 3–8+3–8 frontal chaetae. Tenaculum with more than 20 chaetae. Claw index 2.5–3.8 (see below). Furca 2.0–2.7 as long as head diagonal. Dens 1.6–2.1 as long as manubrium. Mucro with lateral chaeta, apical and subapical teeth subequal. Proportions of body limbs, chaetae covering and integument are not affected by maturity and sex. Morphology of winter form unknown. Distribution and ecology. A. bidenticulata is a transholarctic species (Babenko & Fjellberg 2006, Fjellberg & Bernard 2009). Typical form is a common component of Arctic desert and wet tundra. In more southern parts of Asia the species comprises the closely related populations/species of unclear status and is very common along water streams both in alpine and forest zone. In Nearctic the species probably occurs only in high latitudes being absent in southern areas (Fjellberg & Bernard 2009). A. bidenticulata sensu lato is common all over the Buryatian mountains. In Scandinavia A. riparia tends to replace A. bidenticulata in the forest belt (Fjellberg & Bernard 2009). We did not find such regularity in Buryatia so far but the current material along latitudinal gradients is not sufficient to make a final conclusion.

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.
