Baumann, 1 &male;, 2 &female; (BYUC); Nisqually River, Nisqually, 13 June 1967, R. W. Baumann, 3 &male; (BYUC). <b>Male.</b> Macropterous. Length of forewing 9&hyphen;11 mm. General color, lime green in life, white in alcohol. Head and pronotum without black markings. Dorsal aspect of epiproct elongate, constricted near middle, apex broadly rounded, with numerous shallow marginal crenulations fringing apex (Figs.11&hyphen;14); surface bare in apical half, clothed with dense appressed setae in basal half (Figs. 9&hyphen;16); in lateral view, disc shaped (Figs. 9, 10, 15, 16). Stem clothed with fine setae (Figs. 9, 11, 13). <b>Female.</b> Length of wings 10&hyphen;11 mm. Coloration and markings similar to male. Subgenital plate produced with posterior margin acute to slightly rounded, general outline triangular, margin usually reaching beyond sternum 9 (Frison 1935, Plate XIV, Fig. 41). <b>Diagnosis.</b> The male of <i>A. elevata</i> can be easily distinguished from both <i>A. severa</i> and <i>A. thalia</i>. by the hour glass shape of the epiproct in dorsal view, enlarged at base, and broadly rounded at apex, bearing fringe of shallow crenulations (Figs. 11&hyphen;14) and disc shaped in lateral view (Figs. 9, 10, 15, 16). The subgenital plate of the female of <i>A. elevata</i> is more rounded at the apex (Frison 1935, Plate XIV, Fig. 41) than either <i>A. severa</i> (Lyon and Stark 1997, Fig. 43), or <i>A. thalia</i> (Fig. 24). <b>Remarks.</b> <i>Alloperla elevata</i> is a species that appears restricted to larger Coastal streams and rivers of the Pacific Northwest, from northern California to British Columbia. Ricker (1943) in his work on the stoneflies of southwestern British Columbia considered <i>A. elevata</i> “…enormously abundant on Sweltzer creek, and moderately so in other medium to large streams near sea level. It has been taken in every month but December and January…”. Ricker (1943) described the epiproct of <i>A. elevata</i> as “dumbbell&hyphen; shaped,” however, in 1954 he considered that “straight and dumbbell shapes intergrade, and even coastal specimens vary somewhat in this respect.” Our examination of material indicates that <i>A. elevata</i>, Ricker’s “coastal form”, is consistent in epiproct shape and form (Figs. 9&hyphen;16) throughout its known range. Jewett’s (1959) description of the epiproct of <i>A. severa</i> as “dumbbell shaped” and his use of Frison’s (1935) illustration of that species indicates that he might have only examined specimens of <i>A. elevata</i>. Jewett (1960) did not report this species from California. Gaufin et al. (1972) listed Montana records for <i>A. elevata</i>, but did not include it in the key to the species. These specimens could be either <i>A. severa</i> or <i>A. thalia</i>, since both occur in Montana.

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; both teacher heads agree on what is shown here.
