28. Ephydra (Ephydra) millbrae Jones Figs. 124–126, Map 28 Ephydra millbrae Jones 1906: 155 [United States. California. San Mateo: Millbrae; LT ♂ (designated by Arnaud 1979: 349), CAS (4483)].— Aldrich 1912: 96 –98 [biology].— Wirth 1971: 364 –365 [revision].— Arnaud 1979: 349 [lectotype designation].— Mathis and Zatwarnicki 1995: 243 [world catalog]. Ephydra riparia of authors, not Fallén (misidentification).— Hardy 1952: 467 (list, Hawaii).— Sturtevant and Wheeler 1954: 170 [review]. Diagnosis. This species closely resembles other subcongeners but may be distinguished by the short, fairly blunt scutellum and sparsely setose anepisternum of females and by characters of the male terminalia. Moderately large shore flies, body length 4.25–4.90 mm; generally microtomentose, olivaceous to brownish with coppery and bluish vittae. Head: Mesofrons shiny with bluish green metallic luster. Facial coloration variable, usually whitish but sometimes golden brown dorsally, paler ventrally. Eye nearly round, eye ratio 1.06; gena-to-eye ratio 0.43–0.49. Thorax: Scutum microtomentose, subshiny, especially posteriorly, grayish green with some metallic bronzish tinges; scutellum of female moderately long, bluntly rounded. Acrostichal setae generally fine; both males and females with distinct, large pair of prescutellar acrostichal setae, prescutellar area of female shallowly swollen, generally inconspicuous, but with several setae; anepisternum, especially of female, with sparse setae along posterior margin. Pleural region olivaceous to dark brown. Wing length 3.80–4.25 mm; costal vein ratio 0.25–0.31; M vein ratio 0.84–0.86. Legs mostly yellowish to reddish, some specimens with femora slightly microtomentose, grayish green; tarsal claws about equal to length of tarsomere 4. Abdomen: Tergite 5 of male about 1.5X length of tergite 4. Male terminalia (Figs. 124–126): Surstyli expanded and rounded apically in posterior view, pale colored, usually yellowish, generally setose except at apex and is distal concavity on posterior surface; gonite generally broad, apex with well-developed pointed hook; sternal plate transverse with narrow anterior process forming bifurcate sclerite, transversely ridged midportion not strongly convex ventrally; aedeagus with apex rounded in lateral view, with a sharp medial flange on posterior side distally, membranous anterodistal lobe with very well-developed apical spicules and proximal ridges, recurved basal process short, about 1/3 length of straight portion. Type material. The lectotype male of Ephydra millbrae Jones, designated by Arnaud (1979: 349), is labeled “Ƌ/ Millbrae, San Mateo Co., Cal./Holo- [scratched off] TYPE Ephydra MILLBRAE Jones /7 Ephydra milbrae n. sp. / LECTOTYPE Ƌ Ephydra Millbrae Jones det 1974 PHArnaud & VFLee.” The lectotype is pinned directly mounted, is in good condition and is deposited in the CAS (4483). When Arnaud (1979: 349) designated this lectotype, he commented as follows: “Jones described Ephydra millbrae from an unspecified number of males and females, and the type-locality was given as “very abundant along the southwest shore of San Francisco Bay between the small towns of San Mateo and San Bruno, the center of the colony seeming to be about Millbrae, where the floating puparia and adults often cover the entire surface of the small salt-water ponds.” Three paralectotypes were also designated. Type locality. United States. California. San Mateo: Millbrae (37°35.9'N, 122°23.6'W). Additional specimens examined. MEXICO. Baja California: Gulf of California, Bahía de Los Ángeles (Gulf of California; 28°55'N, 113°30'W), M. C. Van Duzee (ex; CAS).

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.
