Mesembrinella brunnipes Surcouf, 1919: 78 . Lectotype female (MNHN), not examined. Type locality: Bolivia. [NB: Guimar „es (1977) noted that Surcouf did not select a holotype, so he designated a lectotype from one of three conspecific female syntypes from Bolivia.]
Mesembrinella brunnipes: Peris & Mariluis (1984: 260) ; Kosmann et al. (2013: 78); Wolff (2013: 121); Marinho et al. (2017: tab. 1); Cerretti et al. (2017: tab. 2).
Diagnosis. A fairly large brown fly averaging 12 mm (11–13/3) in length. Postpronotal lobe 3x 3; stem vein bare dorsally; wing infuscated; dorsum of abdomen without pits; supravibrissal setae dark brown or black; subcostal sclerite setose; section IV of wing 0.31 of section III; mid and hind femora with basal 1/4–1/2 brown, apical 1/2–3/4 orange; whitish tomentum on abdomen uniform on T1+2–4 vs. the similar M. townsendi , which has pale tomentum in oblique streaks. This species resembles M. bicolor , but has wing with strong, dark infuscated area along costa to R 2+3 instead of wing hyaline with yellowish area along costa.
Redescription. Male. Head. Frons 0.02/1 of head width at narrowest. Fronto-orbital and parafacial pale orange with pale tomentum, frontal seta ascending about 1/3 of distance to vertex; frontal vitta orange, obliterated in upper 2/3; gena: anterior half orange with pale orange tomentum, posterior half orange with silvery tomentum; postgena orange with silvery tomentum; gena and postgena with dark setae, except rear edge of postgena with pale setae; occiput with pale gold tomentum and pale gold setae; median occipital sclerite shiny dark orange; antenna dark orange; palpus typical; eye with median facets about 3x size of lateral facets; ocellar triangle small with ocelli about equal in size; supravibrissal setae dark, ascending about 1/5 of distance to antennal base.
Thorax. Dorsum shiny brown with pale tomentose stripes; pleura dark reddish with pale tomentum; chaetotaxy: ac 2:3, anteriormost postsutural setae may be lacking on one side, dc 2:3, ia 1, ph 1, ppn 3x 3, kat 1:1 or 2:1, meral setae typical, 1 ap converging slightly, sa absent, 2 very weak lat, 1 stout bas, 1 weak pb, 1 disc; subscutellum moderately developed; spiracles medium, pale yellow; legs brown except mid and hind femora with apical 1/4–1/2 orange. Wing heavily infuscated along anterior edge from costa to R 2+3; subcostal sclerite with dark setae; basicosta and tegula orange; section IV 0.31 (0.303 –0.313 /3) of section III; discs of calypters light tan; rim of upper calypter light tan with short reddish setae; rim of lower calypter yellow with long pale-yellow setae.
Abdomen. T1+2 yellow-brown, T3–5 purple-blue with pale tomentum, row of marginal setae on T4; T5 without marginal setae. Terminalia in lateral view with surstylus moderately curved backward ( Fig. 65 View FIGURES 63–68 ); in posterior view cerci short and stout ( Fig. 66 View FIGURES 63–68 ); phallus in lateral view with tiny, short epiphallus ( Fig. 155 View FIGURES 153–162 ); in dorsal view, hypophallic lobes rectangular with prominent coarse serrations along edge ( Fig. 156 View FIGURES 153–162 ); T6, STS7+8, pre- and postgonite, ejaculatory sclerite, ST6 and hypandrium as in Fig. 220 View FIGURES 216–221 ; ST1–5 broad, as in Fig. 263 View FIGURES 252–265 .
Female. Similar to male except frons 0.27 (0.26–0.28/2) of head width at narrowest. T6 of WV shape; T7 slen- der, divided midway; T8 as separate sclerites ( Fig. 307 View FIGURES 306–311 ); ST6–8 and hypoproct as in Fig. 351 View FIGURES 350–369 ; spermathecae filiform ( Fig. 392 View FIGURES 370–400 ); ST1–5 as in Fig. 436 View FIGURES 424–438 .
