This species is distinguished from other species of the E. (En.) teres species group by the pair of dark scutal vittae, male hind femur with ventral knob-like process with tuft of whip-like setae (Figs 231, 232), and epandrium with long, wavy setae. Description. Wing length 5.5–6.5 mm. Male. Similar to E. (En.) teres, except as follows: head with ocellar triangle with pair of long ocellar setae, longer than ocellar triangle. Thorax with scutum with setae increasing in length posteriorly, with posterior seta as long as npl; 3 posterior npl. Scutellum with 1 pair of long sctl, with 1 pair of marginal setae. Hind femur with white ventral pile on basal three-quarters; apical fourth slightly curved and swollen, with oval, knob-like ventral process bearing posterior appendix bearing whip-like tuft of black setae; tuft of anteroventral setae without swelling posterior to knob-like process; cluster of short, curved posteroventral setae posterior to knob-like process, with preapical oblique rows of 4–5 wavy posteroventral setae, as long as width of femur (not homologous to preapical row of posterior setae); without strong preapical anterior seta (Figs 231, 232). Hind tibia greatly narrowed at base; anteroventral digitiform process short, triangular with oblique row of appressed setae, as long as process; posteroventral process short, bifid with tufts of apical setae widely separated; ventral setae distal to processes not thickened; long anterodorsal and posterodorsal setae on apical two-thirds, more than twice as long as width of tibia (Figs 230–232). Hind tarsus with similar long dorsal setae. Abdomen with sternites with long, wavy setae (Fig. 230). Terminalia (Fig. 236): brown with paler phallus. Cercus short, subtriangular, strongly tapered posteriorly to narrow apex; dorsal margin straight, with setae evenly distributed; setae shorter than half width of cercus; base fused to epandrial lamella. Subepandrial process extending to phallus. Epandrial lamella narrow, linear, longer than height; posterior margin strongly upturned; bearing long, wavy setae ventrally, longer than width of lamella. Hypandrium very short, truncate, not prolonged laterally; without setae. Phallus with basal third not greatly expanded, tapered, gently arched anteriorly; apex emerging beyond cercus; apex slender and downcurved in lateral view; with roughened, spiculate surface opposite dorsal margin of epandrium; ejaculatory apodeme oval, half-length of epandrium, Y-shaped, with ventrally positioned lateral apodemes. Female. Similar to female of E. teres, except setae of scutum and scutellum longer. Geographical distribution and seasonal occurrence (Fig. 238). Empis (En.) undulasetosa sp. nov. is known from southern British Columbia, Washington, Oregon and northern California, primarily along the Coast Range. Adults have been collected from April to June. Etymology. The species name is Latin for wavy bristles, in reference to the long, wavy setae on the epandrium of this species. Nuptial gift presentation. Form unknown.

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.
