Figures 70C–D, 72H–I, 80, 96C
DIAGNOSIS: Small to medium-sized fly (ThL 1.02–1.18 mm); dark brown, including entire pleura; frons dark, dull, wide; legs yellow; cheek deep, light brown; postpronotal lobe marking faint, subalar spot very faint or absent; arista with few, very short branches; cerci flattened, positioned low, ventral margins in line with ventral level of epandrium; surstylus apically narrow, with ca. 5 prensisetae; subepandrial appendage well developed; outer paraphyses asymmetrical, relatively short, forming L-shaped structure in lateral view, ventrally with 2 basal ostia; inner paraphysis lost.
DESCRIPTION: Small to medium-sized fly (ThL 1.02–1.18 mm), body dark brown, uniformly so, even entire pleura including katepisternum; legs yellow. Frons dark, blackish-brown dorsally, light brown ventrally at lateral corners; relatively narrow (FML/FMW 0.20–0.28). Cheek deep (EL/CW 7.57–7.62), very light brown. Palp yellow. Postpronotal lobe marking faint, subalar spot extremely faint to absent. Arista: Short, plumose; longest branch D2; A.R. 0.28; 2 dorsal branches at base, 2 ventral branches preapically; branch D3 pointed mediad; arista trunk with short to mediumlength microtrichia to apex. Male genitalia: Epandrium dorsally complete, margin discrete from membrane below; row of long ventral setae in lateral view. Cercus wedge shaped, flattened, dorsally narrow, ventrally expanded with flat margin, extending slightly beyond epandrium in lateral view; very large membranous area dorsally. Surstylus with broad base, apical half a narrow lobe; row of setulae on medial and lateral margins; 5 short prensisetae, apices blunt. Subepandrial appendage present, U-shaped, each distal end connected to membranous sheath bearing microtrichia; roughly heart shaped. Outer paraphyses asymmetrical; short, stout, heavily sclerotized; bases broad, narrowed apically; right paraphysis with bifid spine projected posteriorly, plus 2 smaller, simple ventral spines; left one with 3 short spines; 1 long preapical trichoid sensilla on each, plus several smaller ones, ventrally with 2 small ostia near base. Inner paraphysis lost. Aedeagal apodeme flared with a concave depression; basal end with deep V-shaped notch, heavily sclerotized “flange” arising at the base and connecting to the midpoint; bent nearly 90° in lateral. Hypandrium thin at apex, forming distinct, wrinkled wings adjacent to paraphyses. Ejaculatory apodeme large, equal to depth of epandrium; heavily sclerotized. Head and thorax measurements: (n = 3; Am 433, 1415, 1419) FL/ FW 0.69 (0.62–0.73), EL/EW 1.25 (1.23–1.27), EL/CW 7.58 (7.57–7.62), FML/FMW 0.24 (0.20–0.28), PR /RR 0.41 (0.40–0.44), ThL 1.10 (1.02–1.18 mm).
