Abstract
<i>Sweltsa naica</i> (Provancher) (Figs. 16-20) <i>Perla naica</i> Provancher, 1876:214. Holotype &male; (Quebec Provincial Museum), vicinity of Quebec City <i>Alloperla novascotiana</i> Needham & Claassen, 1925:113. Holotype &male; (Cornell University), Nova Scotia, Truro, synonymy by Ricker, 1952 <b>Material examined. NEWFOUNDLAND:</b> Bowed Brook, Hwy 430, Bellburns, 5 June 1998, B.C. Kondratieff, R. W. Baumann, 13&male;, 1 pharate larva (CSU). <b>PENNSYLVANIA: Westmoreland Co.,</b> Powdermill Run, Powdermill Nature Reserve, 15 May 1993, S.A. Grubbs, 6&male;, 2&female;, 7 larval skins (WKU). Same site, 16 May 1993, S.A. Grubbs, 21&male;, 13&female;, 5 larval skins (WKU). <b>Mature larva.</b> Body length 10 mm. General color brown, head darker over frons (Fig. 16). Pronotum bearing ca. 14 anterolateral setae and ca. 19 posterolateral setae near margin; posterolateral row extends to median suture. Mesonotum bearing ca. 13 prominent outer marginal setae and metanotum bearing ca. 17 prominent outer marginal setae (Fig. 17); intercalary surface of metanotal wingpad with numerous setae. Fore femora with numerous thick setae in basal half and along dorsal margin (Fig. 18); dorsal margin with a few fringe setae. Tibiae with outer fringe setae and inner row of thick setae. Posterior abdominal fringe on tergum 8 with median field occupied by a small group of thin setae, tergum 9 fringe with thick setae in median field (Fig. 19). Cerci with ca. 15 segments; long dorsal setae in segmental whorls about as long as 2 segments (Fig. 20); most apical segments with several long setae visible in profile. <b>Comments.</b> The distinctive shoehorn shaped male epiproct for <i>S. naica</i> suggests it is not closely related to other eastern Nearctic members of the genus, however Surdick (2004) presents evidence which support the species being more closely related to members of the <i>S. onkos</i> complex than to <i>S. oregonensis</i> (Frison) or other western species with similar epiproct structure. Geographically, <i>S. naica</i> is known from West Virginia and Virginia, north through Atlantic Canada (Surdick 2004), where it is often sympatric with <i>S. onkos</i> and sometimes with <i>S. lateralis</i>. Larvae of <i>S. naica</i> are generally similar to those of <i>S. onkos</i>, particularly in sharing long dorsal cercal setae (Fig. 20) and long tibial fringe (Fig. 19), but pre-emergent larvae of the two are distinguished on the basis of abdominal and occipital pigment patterns. <i>Sweltsa naica</i> larvae are the only eastern Nearctic <i>Sweltsa</i> species known to have a dark frons and a relatively pale occipital area.

How this classification was reachedexpand
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.
