Abstract
This paper is the last in a series revising the Nearctic Cybaeinae spider fauna (Araneae: RTA clade: Cybaeidae) exclusive of Cybaeozyga Chamberlin & Ivie. The forested habitats of the west coast of North America are home to a diverse array of endemic Cybaeinae spider taxa. Many of these have very restricted distributions, especially within an area of the western United States of America from the Olympic Peninsula of northwestern Washington to the northern half of the California Floristic Province of California, a well-known biodiversity hotspot. Here we revise the genus Cybaeina Chamberlin & Ivie recognizing three species: the type species Cybaeus minutus Banks (= Cybaeina minuta (Banks)), C. confusa Chamberlin & Ivie, and a single new species C. dixoni Bennett spec. nov. We describe Neocybaeina Bennett gen. nov. with type species Cybaeina xantha Chamberlin & Ivie (= Neocybaeina xantha (Chamberlin & Ivie) comb. nov.) and a single new species N. burnetti spec. nov. Finally we describe Rothaeina Bennett gen. nov. with type species Cybaeina sequoia Roth (= Rothaeina sequoia (Roth) comb. nov.) and four new species R. beaudini Bennett spec. nov., R. jamesi Bennett spec. nov., R. mackinleyi Bennett spec. nov., and R. petersoni Bennett spec. nov. In addition to descriptions of the genera and both sexes of their included species (except for N. burnetti spec. nov. and R. beaudini Bennett spec. nov. which are known from females only), we provide diagnoses, illustrations, distribution maps, and, for the three species of Cybaeina and the five of Rothaeina gen. nov., identification keys. In closing, we discuss conservation implications for this cryptic and infrequently collected group of western Nearctic Cybaeinae, several of which are short-range endemic species.

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
