Tergites 1 and 2 lightly colored. Arista: Very short, plumose; longest branch D2; A.R. 0.25; 5 dorsal, 0 ventral branches, none pointed mediad/laterad; arista trunk with long microtrichia along entire length. Male genitalia: Epandrium separated at midline, ventral margin of dorsal arch distinct from surrounding membrane; ventral portion densely hairy, with a line of single setae ascending ventrally; small anterolateral projection. Cercus thin, crescentic; distinct from surrounding membrane. Surstylus approximately rectangular, middle portion and ventrolateral edge with setulae; 7–9 short, peglike prensisetae, apices blunt; small lateral lobe present, not extending beyond prensisetae. Subepandrial sclerite C-shaped in lateral view, well sclerotized; with subepandrial appendage that is heart shaped in posterior view, apex broad and round. Outer paraphysis laterally flattened, slightly hooked at apex; 3 long spines in lateral view; 2 along middle portion at angle, nearly parallel to each other, distal spine blunt; proximal spine with pointed apex and small preapical tooth; basalmost spine long, apex with small notch. Male sternite 6 moderately sclerotized, developed into sac with faintly cobbled surface. Inner paraphysis lost. Aedeagal apodeme longer than wide, width 0.75× length; curved 90° in lateral view, curved portion forming inflated pockets; distal end with a deep emargination. Hypandrium thickened; apex notched, accommodating outer paraphysis; lateral arm with gonopod, bulging, oriented posteriorly. Ejaculatory apodeme of moderate length, 0.7× length of epandrium.

DISTRIBUTION: Amiota occidentalis is found widely throughout western North America from southern California to British Columbia and east to Utah and Montana. It extends more easterly in the northern parts of its range. COMMENTS: It is unknown whether Amiota occidentalis is attracted to the face and eyes. According to specimen data, it has apparently been collected only by general sweeping and malaise traps, sometimes baited with dry ice (CO 2), a method used to collect tabanids, mosquitoes and other blood-feeding flies. Attraction to CO 2 suggests it is attracted to humans, and that Amiota may use cues other than visual (e.g., mammal eyes) or perspiration scent.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
