Arctic species of the subgenus <i>Symplecta sensu stricto</i> (Diptera: Limoniidae)
Bibliographic record
Abstract
Abstract Species of the subgenus Symplecta Meigen with Arctic, or at least partly Arctic, distributions are revised. Five species are redescribed: S. ( S. ) novaezemblae (Alexander), S. ( S. ) scotica (Edwards), S. ( S. ) mabelana (Alexander), S. ( S. ) sheldoni (Alexander), and S. ( S. ) horrida (Lackschewitz). Two new species are described: S. ( S. ) edlundae sp. nov. (Northwest Territories and Yukon, Canada) and S. ( S. ) echinata sp. nov. (eastern Siberia, Russia). Five new synonyms are proposed: Erioptera ( S. ) sunwapta Alexander and Helobia intermedia Lackschewitz = S. ( S. ) scotica ; Erioptera ( S. ) platymera Alexander = S. ( S. ) mabelana ; S. ( S. ) rotundiloba Podenas and Gelhaus = S. ( S. ) sheldoni ; and Erioptera ( Psiloconopa ) chaetophora Alexander = S. ( S. ) horrida . Symplecta ( Symplecta ) scotica and S. ( S. ) mabelana are restored as full species from subspecies rank. Symplecta ( Symplecta ) horrida , previously placed in Erioptera ( Mesocyphona ) Osten Sacken, is transferred to Symplecta s.s . The distinctions between S. ( S. ) cana (Walker) and S. ( S. ) hybrida (Meigen) are clarified and the sympatric and syntopic occurrences of these species are documented. A key to the species treated, and illustrations of both male and female terminalia, are provided and the distribution of each species is outlined.
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.
