Distinguishing the male of N. xantha comb. nov. is discussed in the genus diagnosis. Distinguishing the female of N. xantha comb. nov. from that of N. burnetti spec. nov. is discussed in the diagnosis of N. burnetti spec. nov. Description. As in diagnosis and description of the genus and the diagnosis of N. burnetti spec. nov. Additional descriptive characters presented here. Abdomen usually patterned (holotype unmarked), legs unbanded. Male: (n=14). Patellar apophysis (Figs 18, 31–34) elongate, curved dorsally, with tapered tip bearing three to six peg setae. Retrolateral tibial apophysis (Figs 31–35) with medial component present but greatly reduced, usually represented by a single short stout basally articulated seta (or, occasionally, a rigid spine-like process) situated distal to dorsal row of tibial trichobothria (Fig. 35), rarely such a seta or process absent; distal component of retrolateral tibial apophysis nearly as long as tibia, somewhat swollen anterolaterally. Genital bulb (Fig. 29–30) with embolus moderately long, thin; proximal arm of tegular apophysis laterally flattened with short, acuminate tip. Measurements (n=12). CL 1.78–2.18 (1.96+0.13), CW 1.33–1.70 (1.47+0.11), SL 1.00–1.17 (1.10+0.06), SW 0.94–1.07 (1.01+0.04). Female: (n=20). Atrium (Figs 36, 38–39) anteriorly located on epigyne, inconspicuous (barely discernible in uncleared epigynes). Vulva (Figs 37–39) with copulatory ducts separated; spermathecal heads at anterior margin of spermathecae, undifferentiated from spermathecal stalks; stalks short; Bennett’s glands large, conspicuous; spermathecal bases usually visible through epigynal integument (Fig. 36), large, bulbous, rounded with short, slightly constricted anterior region adjacent to Bennett’s glands gradually expanding into posterior bulbous region; fertilization ducts attached to ventral surface of posterior region of bases. Measurements (n=15). CL 1.55–1.95 (1.73+0.11), CW 1.10–1.33 (1.27+0.10), SL 0.91–1.04 (0.96+0.05), SW 0.81–0.94 (0.86+0.04). Holotype CL 1.58, CW 1.20, SL 0.91, SW 0.81. Distribution and natural history. (Fig. 84). Neocybaeina xantha comb. nov. is known only from Coos, Douglas, and Lane Counties of western Oregon, U.S.A. where it has been recorded from the southern upland reaches of the Willamette Valley to the southwestern slopes of the coastal mountains. Males have been collected from July to early August. This species was most recently recorded in 1962 and its conservation status is unknown.

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 it
