DNA barcoding resolves species complexes in Stigmella salicis and S. aurella species groups and shows additional cryptic speciation in S. salicis (Lepidoptera: Nepticulidae)
Bibliographic record
Abstract
We sequenced the mitochondrial barcoding marker COI and nuclear marker EF1-alpha for most Nordic and other European species of the Stigmella salicis and S. aurella species groups. In the S. salicis group both markers confirm the synonymy of S. lappovimella with S. zelleriella. Specimens previously identified as Stigmella salicis and S. vimineticola are shown to form a complex of several cryptic species for which the taxonomy needs to be worked out. The species previously recorded as S. vimineticola from Norway represents probably an unnamed species. In the S. aurella group, the oligophagous Rosaceae feeders S. aurella and S. poterii are confirmed to be each a single oligophagous species. The synonymy between Stigmella ulmariae from Filipendula ulmaria and S. filipendulae from Filipendula vulgaris is corroborated.
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.
