A review of the genera Georthocladius Strenzke, 1941 and Parachaetocladius Wülker, 1959 (Chironomidae, Orthocladiinae): new species descriptions, and keys based on the morphological characters of adult male
Bibliographic record
Abstract
A systematic revision of the genera Georthocladius Strenzke, 1941 and Parachaetocladius Wülker, 1959, and a key to adult males is presented. Two new Holarctic species are diagnosed and described based on morphological characters of the adult male: Parachaetocladius pyrenaeus sp. n. (Palaearctic region) and Parachaetocladius broankerothurrie sp. n. (Nearctic region). Additional taxonomic notes on related genera of Orthocladiinae and synonymies for four species from Japan are also provided, which include: Parachaetocladius kuramasingularis (Sasa, 1989), Parachaetocladius kamiovatus (Sasa & Hirabayashi, 1993), and Parachaetocladius sunabaabeus (Tanaka & Sasa, 2001) being the junior synonyms of Parachaetocladius akanoctavus Sasa & Kamimura, 1987. An updated checklist of both Georthocladius and Parachaetocladius species with taxonomic remarks, ecology, discussions and a provisional key for adult male are also provided.

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; a candidate call from one teacher head, not a consensus.
