DIAGNOSIS: Large fly (ThL 1.51–1.71 mm), dark brown, legs yellow; outer paraphysis laterally flattened, with hook on distal end, 2 short, blunt spines along middle portion of dorsal margin, base minutely serrate; inner paraphysis lost.

DESCRIPTION: Large fly (ThL 1.51–1.71 mm), dark brown, legs yellow. Frons light brown on ventral half, dorsal half of head darker. Facial marking large (FML/FMW 0.29–0.38). Cheek deep (EL/CW 7–13.66), posterior milky white. Marking under wing base prominent, large, milky white, margins clearly defined. Haltere yellow. Tergites 1 and 2 lightly colored. Arista: Short, plumose; longest branches D1 and D2; A.R. 0.28; 3 long dorsal, 2 short ventral branches; branch D3 pointed mediad; arista trunk with short-medium length microtrichia along most of its length. Male genitalia: Epandrium separated at midline with a large gap, margins distinct from surrounding membrane; long lobe ventrally, densely haired, single line of setae ascending dorsally; anterolateral projection small, oriented anteriorly. Cercus semicircular, margins entirely distinct from surrounding membrane. Surstylus approximately rectangular, ventral half covered in scattered setulae; 12 short, peglike prensisetae, apices blunt; small fingerlike lateral lobe, not extending beyond prensisetae. Subepandrial sclerite C-shaped in lateral view, with appendage heart shaped in posterior view, invaginated medially. Outer paraphysis laterally flattened with hook on distal end; 2 short, blunt spines along middle portion in lateral view; small proximal “wing” at base, minutely serrate. Inner paraphysis lost. Aedeagal apodeme as wide as long; curved 90° in lateral view, curved segment forming deep pockets; distal end slightly flared with a deep central emargination. Hypandrium thin, apex with gap; triangular in anterior, accommodating paraphysis; lateral arm with prominent gonopod, triangular, ventrally pointed. Ejaculatory apodeme long, 0.8× length of epandrium. Head and thorax measurements: (n = 5; Am 4, 457, 753, 1483,×1504) FL/FW 0.73 (0.66–0.81), EL/EW 1.30 (1.21–1.43), EL/CW 9.34 (7–13.66), FML/FMW 0.34 (0.29–0.38), PR / RR 0.60 (0.46–0.77), ThL 1.63 (1.51–1.71 mm).

ETYMOLOGY: From the Latin amputata , feminine past participle, for “pruned” or “amputated,” in reference to the stublike nature of the prongs on the outer paraphyses, which are much longer in other closely related species.

DISTRIBUTION: This species has a large distribution from Chiapas State in Mexico north through central Arizona.

COMMENTS: The paratype described in Máca (2003) as an “aberrant individual” from the type series of A. nebojsa Máca belongs is Amiota amputata . See Comments under that species.
