Abstract
26. Zapada katahdin Baumann & Mingo, 1987 Katahdin Forestfly http://lsid.speciesfile.org/urn:lsid: Plecoptera.speciesfile.org:TaxonName:5994 (Figs. 165‒168) Zapada katahdin Baumann & Mingo 1987:252. Holotype male (United States National Museum), Katahdin Stream, Penobscot Co., Maine, USA Nemoura (Zapada) sp.: Harper & Hynes, 1971:1140 Zapada katahdin: Grubbs et al., 2015:1319 Distribution. Canada: LB, NS, PQ. USA: ME, NH (DeWalt et al. 2022) Male. Macropterous. Body length 6.1–6.3 mm, forewing length 6.7–7.3 mm (n = 3). Four unbranched cervical gills are present. The L:MW ratio for the outer lateral gills is ca. 4.2 compared to ca. 5.2 for the inner medial gills (Fig. 167; Grubbs et al. 2015). Cerci simple and unmodified (Fig. 165). Paraprocts with two sclerotized lobes; inner lobes short and thin, outer lobe broadly quadrate. Epiproct recurved over 10 th tergite (Figs. 165–166); broadest basally and slightly tapering to a truncate apex in dorsal view, revealing the large membranous area and the paired dorsal hooks (Fig. 165); the dorsal sclerite and membranous area extend the entire length of the epiproct in lateral view (Fig. 166); ventral sclerite broad at base but narrowed markedly to apex, nearly engulfed by dorsal sclerite along lateral margins, bearing an irregular row of stout spines. Female. Macropterous. Body length 7.5–9.1 mm, forewing length 8.7–9.6 mm (n = 5). The 7 th sternum is enlarged as a subtruncate plate extending well over 8 th sternum; posterior margin of 8 th sternum slightly concave medially (Fig. 168). Larva. Full description and habitus illustration in Bauman & Mingo (1987). The brief description and partial illustrations by Harper & Hynes (1971) from Ungava, Quebec also refer to this species. Comments. This is a northeastern Nearctic species, known from New Hampshire, Maine, and Nova Scotia northward to Labrador and Quebec (Grubbs et al. 2015, DeWalt et al. 2022). FIGURES NOTE: Some line drawings are missing specific location data due to details that were not present on the original illustrations.
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.
