Cryptochironomus Kieffer from Lake Winnipeg, Canada, with a review of Nearctic species (Diptera: Chironomidae)
Bibliographic record
Abstract
Cryptochironomus imitans sp. n. from Lake Winnipeg, Manitoba, Canada, is described in all stages and both sexes. Six additional species of Cryptochironomus Kieffer, 1918 are recorded from Lake Winnipeg. C. stylifera (Johannsen, 1908) is shown to be a senior synonym of C. redekei Kruseman, 1933. The immatures of C. stylifera, C. digitatus (Malloch, 1915), C. ramus Mason, 1985, and C. curryi Mason, 1985, the male of C. ramus and the female of C. curryi are described or redescribed, and additional information given on imagines of C. stylifera, C. digitatus, C. curryi and C. blarina Townes, 1945. The male of a variety of C. ramus is described, and a pupa of C. eminentia Mason, 1985 figured. Keys are given to Nearctic males, pupae and larvae of Cryptochironomus. The distribution of Cryptochironomus in Lake Winnipeg is mapped and discussed. The separation of larval instars is shown approximately to follow Dyar’s rule.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
