Pteronidea cognata Lindqvist, 1958: 108–111. Synonymy with approximatus by Lindqvist (1962a). Diagnosis Typically, the extensively pale head (including antenna), thorax, abdomen, and costa generally paler than pterostigma distinguish males and females from the others in the group. Smaller subapical tooth of claws compared to E. ribesii (subapical tooth broad and as long as apical tooth) and larger compared to E. gracilidentata additionally distinguishes E. leucotrocha females from these two species. Males of E. gracilidentata also tend to have a smaller subapical tooth (can be almost absent) than in E. leucotrocha, but also have a different colour pattern, with the black head and thorax contrasting with the yellow abdomen (in E. leucotrocha the colouration of head and thorax varies together with the abdomen, in a similar way, from mostly black to extensively pale). Males of most other species can be distinguished from E. leucotrocha by the shape of the projection of tergite 8 (see under E. ribesii) and penis valves (see under E. ribesicola, E. similator, and E. vastatrix). Darker specimens of E. leucotrocha might not be clearly distinguishable from E. quieta, but usually the clypeus seems to be more deeply excised in E. quieta than in E. leucotrocha. The male type specimen of caudalis seems to fit better with leucotrocha (projection of tergite 8 broader, less emarginate clypeus) than ZMUO.029729 (quieta). Males can also be rather dark (ZMUO.036046): antenna black, head slightly pale around eyes (clypeus, labrum, lower orbits and slightly supraclypeal area pale), mesepisternum black, abdomen dorsally mostly black. Type material examined Lectotype Nematus leucotrochus, here designated GERMANY – Niedersachsen • ♀; Harz; 51.8° N, 10.3° E; W. Saxesen leg.; ZSM, GBIF-GISHym3338. Paralectotype Nematus leucotrochus GERMANY • 1 ♀; same data as for lectotype; NFVG, GBIF-GISHym4684. Lectotype Nematus haemorrhoidalis GERMANY • ♂; northern Germany [according to Hartig 1840: 22]; ZSM, DEI-GISHym12490. Lectotype Nematus caudalis, here designated RUSSIA – Tatarstan • ♂; Kasan Province; 55.8° N, 49.1° E; E. Eversmann leg.; ZIN, DEI-GISHym30028. Lectotype Nematus approximatus GERMANY – Nordrhein-Westfalen • ♀; Aachen area; 50.77° N, 6.09° E; ZSM, GBIF-GISHym3203. Holotype Pteronidea cognata FINLAND – Uusimaa • ♀; Helsinki, Munksnäs [Munkkiniemi]; 60.22° N, 24.89° E; 2 Apr. 1955; E. Lindqvist leg.; MZH, http://id.luomus.fi/GL.2455. Host plants Ribes spp. Possibly there are regional differences in preferences for host species: in Finland R. rubrum L. is preferred, whereas in Germany and the British Isles R. uva-crispa L. is the usual host (Benson 1958a; Pschorn-Walcher & Altenhofer 2000). According to Viitasaari (1980) frequently also R. nigrum L., although this could refer to E. quieta even though Viitasaari (1980) separated this species from E. leucotrocha. Genetics COI Based on 9 specimens, maximum within-species distance is 5.17% and the nearest neighbours, diverging by a minimum of 0.46%, are Euura quieta and E. gracilidentata. Nuclear Based on 10 specimens, maximum within-species distance is 0.86% (0.64% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.5%, is Euura gracilidentata. Distribution and material examined Palaearctic. Specimens studied are from Finland, Germany, Russia, Sweden, and the United Kingdom.

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.
