Diagnosis. A medium-sized shiny dark brown fly averaging 10.7 mm (10–11/3) in length. Black postocular setae only extending 2/3 of way to gena vs. black postocular setae extending all the way to gena in L. perisi ; palpus slen- der, dark brown to black vs. orange in L. perisi ; fore and mid trochanters and femora dark brown (hind ones sometimes yellow) vs. trochanter and femora yellow in L. perisi ; basal half of tarsal claw white in both L. nigripes and L. perisi ( Fig. 10 View FIGURES 9–14 ), darkened orange, brown or black in other Laneella ( Fig. 11 View FIGURES 9–14 ); wing with distinct infuscation along the length of the costa, vs. only distal end of wing infuscated in L. perisi ; T4 with whitish tomentum on anterior half vs. with four large spots of whitish tomentum midsegment in L. perisi .

Redescription. Male. Head. Frons narrow, 0.015/1 of head width at narrowest; fronto-orbital and parafacial pale orange with heavy silvery tomentum; frontal setae ascending about halfway to vertex; frontal vitta dull orange with pale tomentum, obliterated about midway; gena yellowish, anterior half with dark setae, rear half with pale setae; postgena yellowish with pale setae; occiput with pale tomentum and yellow-gold setae, median occipital sclerite shiny dark orange; antenna: pedicel, first flagellomere, and arista dark orange; eye with median facets about 4x size of lateral facets; ocellar triangle tiny, anterior ocellus about 1.5x size of posterior ocelli; supravibrissal setae brown, in cluster at base of facial ridge, like in L. perisi .

Thorax with dorsum and pleural areas orange-brown; dorsum with four whitish tomentose stripes. Chaetotaxy: ac 2:3, dc 2:3, ia 1, ph 1, ppn 3x 3, kat 2:1, meral setae long, slender and tan; 1 pair converging ap, sa absent, 1 lat, 1 stout bas, 1 weak pb, 1 disc; subscutellum weakly developed; spiracles pale yellow, medium in size. Legs. Trochanters and femora dark brown (sometimes yellowish on hind leg), vs. yellow in L. perisi .

Female. Similar to male except frons 0.26/2 of head width at narrowest, eye with median facets about 2x size of lateral facets. Terminalia with T6 of FU shape; T7 anterior edge with semicircular depressed area midway; T8 as separate sclerites ( Fig. 284 View FIGURES 282–287 ); ST6–8 and hypoproct as in Fig. 328 View FIGURES 326–349 ; spermathecae tuberform ( Fig. 372 View FIGURES 370–400 ); ST1–5 as in Fig. 413 View FIGURES 411–423 .

Material examined. Brazil, Federal. 1 ♂*, 1 ♀ *, Rio de Janeiro, ix.1938, M.E.S. Bras. ( USNM) . São Paulo. 1 ♀, Boraceia, Salesopolis , 15.iii.1972 ( NHMUK) ; 1 ♀ ♦ ( TLW385 ) , Santo Andre, R.B.A. da Sierra de Paranapiacaba , 23°46ʹ46ʺS 46°18ʹ29ʺW, 21.xii.2010, Malaise 3, M. Sato, S. Nihei ( MZSP) GoogleMaps ; 1 ♂, same data except 19.iv–23.v.2011, Malaise 1, P. Moll, F. Gudin. ( MZSP) GoogleMaps .

Distribution. Brazil. Bonatto (2001) also listed it from Paraguay.

Remarks. A single specimen was barcoded during this study ( TLW 385) and two additional sequences were taken from GenBank ( KR820705 View Materials , KR820706 View Materials ). All sequences clustered together close to L. fusconitida and L. patriciae ( Fig. 488 View FIGURE 488 ). The genetic distance between L. nigripes and L. fusconitida is 11%, as is the distance between L. nigripes and L. patriciae .
