Amiota nebojsa Máca, 2003: 269 (original description); Brake and Bächli, 2008: 254 (world catalog).

DIAGNOSIS: Large fly (ThL 1.73–1.92 mm), dark brown and glossy; outer paraphysis in lateral view forming distinctive structure: laterally flattened with a distal hook, proximal end with 2 long, nearly parallel spines very near each other, basal spine shorter; inner paraphysis lost.

DESCRIPTION: Large fly (ThL 1.73–1.92 mm), dark brown and glossy, legs yellow. Frons shiny; dark brown dorsally, light brown ventrally. Cheek deep, variable in size (EL/CW 6.76– 22.66), milky white posteriorly. Facial marking large (FML/FMW 0.35–0.42). Palp brown. Haltere yellow. Tergites 1 and 2 lightly colored. Arista: Short, plumose; longest branch D4; A.R. 0.28–35; 4–5 long dorsal, 0 long ventral branches; D4 pointed laterad; arista trunk with very long microtrichia along entire length. Male genitalia: Epandrium separated at midline, distinct from membrane surrounding cerci; middle section without long setae; small anterolateral projection. Cercus oval shaped, distinct from surrounding membrane. Surstylus wide, almost square; ventral half with 18–20 long, scattered setulae; 11–13 peglike prensisetae, apices blunt, comblike; small lateral lobe present, oriented anteriorly. Subepandrial sclerite well sclerotized, C-shaped in lateral view; subepandrial appendage extending posteriorly; apex heart shaped in posterior view. Outer paraphysis long, laterally flattened, heavily sclerotized; hook on distal end; proximal end with 2 long spines in lateral view, nearly parallel to each other, distal spine slightly shorter; sternite 6 modified into large membranous sac, lightly sclerotized, basal portion microtrichose, cobbled distally. Inner paraphysis lost. Aedeagal apodeme as long as wide, strongly curved in lateral view; proximal region inflated, forming pockets; distal end widely flared with deep concave depression. Hypandrium thin, apex notched, accommodating outer paraphysis; lateral arm with a large gonopod, rectangular, oriented posteriorly. Ejaculatory apodeme very large, nearly as long as epandrium. Head and thorax measurements: (n = 5; Am 10, 11, 458, 637, 741) FL/FW 0.66 (0.61–0.73), EL/EW 1.38 (1.35–1.41), EL/CW 12.54 (6.76–22.66), FML/ FMW 0.38 (0.35–0.42), PR /RR 0.56 (0.42–0.70), ThL 1.80 (1.73–1.92 mm).

Wheeler, 2074, [paratype of A. buccata Wheeler , see Discussion under that species] 1♀ (Am 8, AMNH).

DISTRIBUTION: This species is found in the mountainous regions throughout Arizona and New Mexico, as well as Guerrero State in southern Mexico.

COMMENTS: When Máca described A. nebojsa (2003) , he cited a paratype in the type series as an “aberrant individual.” This paratype is a different species, Amiota amputata . Amiota nebojsa and Amiota amputata have overlapping distributions and specimens in DEBU of the two species were also collected in the same series. This species exhibits the characteristic behavior of attraction to the eyes and face common to many Amiota .
