Résumé
Amiota imperator, sp. nov. Figures 69E–F, 72F, 78, 96A DIAGNOSIS: Large fly (ThL 1.60–1.73 mm), honey to light brown, legs white, middle tibia with comb of ~20 upright setae; arista with medium to long plumosity; epandrium squat, broader than deep, dorsally complete, cercus pendulous; subepandrial sclerite with pair of slender, spinelike appendages that project forward; aedeagal apodeme long and slender, length almost 2× width of base; inner paraphysis with distal, globose lobe densely covered in membranous scales. DESCRIPTION: Large fly (ThL 1.60–1.73 mm), color always light, varying from golden honey to light brown (darkening in older museum specimens), abdomen darker, legs brilliant milky white (sometimes yellowing in older material), setation on body jet black. Cheek milky white posteriorly. Palp yellow. Katepisternum darker than rest of pleuron. Middle tibia with comb composed of ~20 setae, length of longest setae approximately equal to width of tibia, central setae slightly longer than those flanking the ends of the comb. Tergites 1 and 2 lightly colored. Arista: Medium, plumose; longest branches D3– D4; A.R. 0.36; 6 dorsal, 2–3 ventral branches; D5 pointed laterad; arista trunk with very long microtrichia that shorten apicad. Male genitalia: Epandrium squat, width ~0.7× height; dorsally complete, not medially split; ventral lobe rounded, with ~15 medium-length setae, ~8–9 setae clustering near apex of epandrium, long setae absent from medial area of epandrium. Cercus grading into surrounding membrane, not recessed into epandrium, pendulous (ventral margin overhanging surstyli). Surstylus with 7 prensisetae, apices blunt, becoming smaller dorsally, spinelike seta arising below the most medial prensiseta; entire surstylus distally setulose. Subepandrial sclerite moderately sclerotized, shieldlike; with pair of long, slender, spinelike processes arising from anterior portion, pointing backward. Outer paraphyses (?) apparently fused distally into a small membranous lobe that is bifid and with a deep notch, lateral surfaces each with pair of sensilla. Inner paraphysis a heavily sclerotized digitiform lobe, the apex with a globose membrane densely covered in minute lanceolate scales. Aedeagal apodeme distinct, slender, length more than 2× width of base; tapering past middle point, “distal plate” expanding, almost circular, not wider than base; single flange forming a central column. Hypandrium simple, incomplete in middle; lateral arms slightly thickened with membranous, ventrally pointed gonopod. Median membranous structure between paraphyses (?aedeagus), with central swale and covered with setulalike projections. Ejaculatory apodeme small and stout, sclerotized, length ~0.4× depth of epandrium.

ETYMOLOGY: From imperator, Latin meaning “emperor, commander-in-chief, ruler,” in reference to the size of this new species, among the largest in Eastern North America, and its distinctiveness. DISTRIBUTION: Amiota imperator is found throughout Eastern North America. Of note, this striking, new species was collected in the Thaines Family Forest of the New York Botanical Garden, located in the Bronx, New York City. COMMENTS: Pinned specimens of this species can look remarkably similar to species of the rufescens species group in size and color. Amiota imperator can be separated from these species by the comb on the midtibia of the males. This species is uncommon in most localities, usually collected as one individual rather than a series. Three specimens (DEBU) were caught via malaise and pan traps. Amiota imperator is likely the species referred to as “ Amiota species B ” by Wheeler (1952), although none of the specimens collected in Maine have been seen except for the genitalia of a male on a slide (no pinned material) in the collections of the AMNH. This species exhibits the characteristic behavior of attraction to eyes and face common to many Amiota.

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.
