Diagnosis: Medium brown and yellow species. Frontal vitta at narrowest point as wide as anterior ocellus. Parafacial with 3 to 4 setulae in basal first quarter. Antenna and palpus brown. Scutum grey with brown vittae along acr, dc and spal lines. One pra very near spal, almost indistinguishable from ground setulae. T 2 constricted in basal half, lacking subbasal protuberance. C3 with 2 p at apex of posterior margin. F3 slightly curved, with a conspicuous preapical protuberance on posteroventral surface and 1 row of long and thin hair-like pv forming a long and curled preapical tuft, 3x femoral width, coinciding with the preapical protuberance.

Description

Male: body length 5-6 mm

Head: Frontal vitta light brown pruinose, at narrowest point as wide as anterior ocellus. Fronto-orbital plate and facialia heavy silver pruinose; frons at uppermost fr 0.6x width of anterior ocellus. Eye bare; pocl of uniform length. Ten fr, as long as flagellum. Parafacial silvery, at base of flagellum 0.75x with of same, and bearing 3 to 4 setulae in basal first quarter. Facial carina and gena dark grey. Scape and pedicel light brown, flagellum 2.5x as long as wide and light brown, light grey pruinose at apex. Arista light brown, short pubescent. Palpus dark brown, spatulated, the apex 3x width of base. Lower oral margin slightly convex and grooveless.

Thorax: Scutum grey with brown vitta along acr line that continues in scutellum forming a transverse line, broader brown vittae along dc lines which disappear between 4th and 5th dc, and brown postsutural vittae along spal lines; apex of scutellum light brown; pleura grey; 3+3 acr, a fourth postsutural acr before scutellum and 1 prescutellar acrs; 2+3 dc; pprn covered with setulae; 1 pra very near spal, almost indistinguishable from ground setulae; 2 prepm surrounded by 3 or 4 setulae.

Legs: Light brown, tibiae slightly yellowish and tarsi black. F1 slightly globose (length/width = 5.8); with 1 row of pd; 2 rows of p; 2 to 3 rows of very short pv and 4 to 5 long pv in apical fourth. T 1 with 1 preapical pd; 1 apical v and pv. Fore tarsomere 1 0.3x length of T 1; tarsomere 4 as long as broad. F2 with 1 row of ad; 3 rows of very short a; 1 row of long av at base, shorter towards apex; 1 basal long pv and two rows of pv spaced at base, grouped at apex, posterior row long and hooked, and ventral row shorter and hooked; 1 row of hair-like p spaced at base, stouter and ventrally directed at apex. T 2 constricted in basal half, lacking subbasal protuberance; ventral pubescence long, slightly longer than 0.5x femoral width; with 1 submedial and 3 apical a; 1 subapical ad; 1 very long apical av; with 1 submedial and 1 apical pd; 1 apical p and 1 apical pv. C3 with 2 p at apex of posterior margin. F3 normal (length/width = 6.38), slightly curved, with a conspicuous preapical protuberance on posteroventral surface; 1 row of ad, dorsally directed towards apex; 1 row of av longer towards apex, interrupted at sub apex and 1 apical av; 1 row of long and thin hair-like pv, forming a long and curled preapical tuft, 3x femoral width, coinciding with the preapical protuberance ( Fig. 10A View FIGURE 10 ). T 3 with 1 submedial and shorter preapical d; 1 submedial and 1 apical ad, lacking medial row; 4 medial, 1 stronger preapical and 1 apical av ( Fig. 10A View FIGURE 10 ).

Wing: Translucid, slightly brown yellowish. Upper calypter rounded and lower one oval, both white. Knob of halter yellow-whitish, base light brown.

Abdomen ( Fig. 10B View FIGURE 10 ): Heart-shaped, tergite 2 twice as broad as tergite 4; heavily grey brown pruinose, yellow at base of tergite 1, and anterior lateral margins of tergites 2, 3, and 4. Hypopygium not protruding.

Postoabdomen: Posterior margin of sternite 5 bilobated, and bearing most setae ( Fig. 10C View FIGURE 10 ). Hypandrial arms directed outwards; postgonites inconspicuous; aedeagus membranous ( Fig. 10D View FIGURE 10 ). Cercal plate fused; baciliform process tooth-shaped; surstyli very broad at base, thin and curved at apex, emerging from dorsal basal area ( Fig. 10 View FIGURE 10 E-F).

Female: body length 4.9-5.1 mm. Differs from male as follows:

Head: Frontal vitta dark brown to reddish brown. Ocellar triangle extending up to lower orb. Frons and vitta broad, the distance between eye margins is broader than 0.33x head width. Eight to nine fr of irregular length. Upper and lower orb present, and 1 row of fronto-orbital setulae.

Legs: F1 with 1 row of p as long as femoral width and 1 or 2 shorter rows of p; 1 row of very short pv at base, and 4 to 5 longer pv at apex. F2 anteroventral surface bare; row of pv very short, less than 0.25x width of femur. T 2 cone-shaped, base narrower than apex; pubescence on ventral surface absent; 2 submedial and 1 apical av-v. C3 with 1 p at apex of posterior margin. F3 lacking ventral protuberance; with 1 row of av and 2 apical av, longer than femoral width; lacking preapical tuft of pv.

Abdomen: Heart-shaped, tergite 2 more than 2x width of tergite 4, this shape much more pronounced than in male; dark brown in ground colour, anterior lateral margins of tergites 2, 3, and 4 yellow or light grey.

Postabdomen: Cerci normal, short; anal plate longer than broad and uniformly covered with setulae; sternite 8 reduced to a posterior pair of plates bearing two setae and four to five setulae; post abdominal spiracles 7 and 8 in tergite 6 ( Fig. 10G View FIGURE 10 ). Two pear-shaped and grooved spermathecae, with partially sclerotized ducts ( Fig. 10H View FIGURE 10 ).

Distribution: NEOTROPICAL: Peru, Bolivia, Brazil, Uruguay, Paraguay, and Northeastern Argentina.
