Diagnosis. A medium-sized reddish-brown fly similar to L. nigripes and averaging 11.4 mm (11–12/5) in length. Black postocular setae extending all the way to gena; palpus typical, orange and robust, whereas in L. nigripes it is slender and dark brown. Wing with distinctive faint darkened area on distal 1/3, also with faint darkened area near distal end of CuA2; base of tarsal claw white, as in L. nigripes ( Fig. 10 View FIGURES 9–14 ). T4 with 4 large spots of silver tomentum vs. solid silvery tomentum on anterior half in L. nigripes .

Redescription. Male. Head. Frons 0.012 (0.010 –0.015 /5) of head width at narrowest. Fronto-orbital with silvery tomentum over orange cuticle, fronto-orbitals touching midway; frontal setae ascending about halfway to vertex; frontal vitta dark orange, obliterated about midway; parafacial bright silvery; gena dull orange with irregular silvery tomentum, horizontal row of stout setae along ventral ridge, and scattered small dark setae; postgena pale orange with few dark setae anteriorly, otherwise with long golden setae; occiput with silvery tomentum and golden setae; postocular row of short, dark setae; median occipital sclerite shiny dark orange; antenna orange, first flagellomere and arista dull orange-brown; palpus typical; eye with median facets about 4x size of lateral facets; ocellar triangle tiny, ocelli about equal in size; supravibrissal setae in cluster at base of frontal ridge, ascending only about 1/8 of distance to antennal base.

Thorax with dorsum and pleural areas orange-brown; dorsum with four whitish tomentose stripes alternating with three dark orange areas. Chaetotaxy: ac 2:3, dc 2:3. ia 1, ph 1, ppn 3x 3, kat 2:1, meral setae long, tan and slen- der, 1 pair converging ap, 1 sa, 1 weak lat, 1 stout bas, 1 weak pb, 1 disc; subscutellum weakly developed; spiracles medium-sized, pale yellow. Legs: femora orange, tibiae and tarsi dark brown with black setae. Wing with distal third infuscated, darker near costa, with another dark area near distal end of CuA2; subcostal sclerite bare, with tan tomentum; basicosta golden, tegula tan; section IV 0.25 of section III; discs of upper and lower calypters tan; rim of upper calypter dark with short reddish setae, rim of lower calypter pale with long reddish setae.

T1+2 with anterior 2/3 yellow, posterior 1/3 dark brown with small yellow section midway; anterior half of T3 with pale tomentum, posterior half dark brown; T4 dark brown with four pale spots of whitish tomentum midway; T5 dark brown with irregular pale setae; T3 with 2–3 stout lateral marginal setae; T4–5 with row of stout marginal setae; disc of T5 without row of stout setae, whole segment with short fine setae. Terminalia in lateral and posterior views with surstyli and cerci very similar to those of L. nigripes ( Figs 21–22 View FIGURES 21–26 ); phallus in lateral view with epiphallus slightly broader than in L. nigripes ; in dorsal view hypophallic lobe rounded, with coarse serrations ( Figs 111–112 View FIGURES 105–114 ); T6, STS7+8, pre- and postgonite, ejaculatory sclerite and ST6 as in Fig. 198 View FIGURES 195–201 ; ST2–5 broader than in L. nigripes ( Fig. 242 View FIGURES 239–251 ).

Female. Similar to male except frons 0.268 (0.26–0.27/5) of head width at narrowest, eye with median facets about 2x size of lateral facets, ocellar triangle large, anterior ocellus larger than posterior. T6 of FU shape, almost flat; T7 continuous with semicircular posterior depression midway; T8 as two separate sclerites, epiproct bilobed ( Fig. 285 View FIGURES 282–287 ); ST6–7 and hypoproct as in Fig. 329 View FIGURES 326–349 ; spermathecae distinctly tuberform ( Fig. 373 View FIGURES 370–400 ); ST1–5 slender compared to other Laneella spp. ( Fig. 414 View FIGURES 411–423 ).

Distribution. Colombia, Costa Rica, French Guiana. Bonatto (2001) listed Ecuador and Brazil.

Remarks. Five specimens ( TLW 271–275) were barcoded; they formed two distinct clusters: one including four specimens from Costa Rica, the other including one specimen from French Guiana ( Fig. 488 View FIGURE 488 ) with a genetic distance of 4.8%. This suggests that the French Guiana specimen belongs to a separate species. The morphology of this specimen was intermediate between the typical L. perisi and L. nigripes , but the latter was even more different with a 10% genetic divergence. No other specimens of this species were found between Costa Rica and French Guiana, and geographical separation likely explains this divergence. The French Guiana specimen is like L. perisi in wing infuscation and palpus color (except for the darkened tip, as in L. nigripes ) and has T4 with pale spots. It is like L. nigripes in having mid and hind femora dark on distal half, not all black, and postocular setae orange; T6–8 of female also looks more like L. nigripes . Further studies are needed to determine whether this specimen belongs to a separate species.
