Diagnosis: these characters apply only to the male sex. Eye with sparse setulae; 10 fr; pedicel dark brown with margin yellowish; arista brown with yellowish base; wings yellowish; halter with whitish stem and knob; abdomen with tergites 3–4 translucent-yellow with media vitta brown; fore femur with 2 rows of p; hind femur with 3 rows of short a, 5–7 long and thin pv on the protuberance; cercal plate weakly fused; surstylus with inner median projection sclerotized; bacilliform process cuneiform.

Male Measurements: 4.27–4.48 mm (body length); 4.30–4.56 mm (wing length).

Head ( Figs. 3View FIGURES 1–6, 9View FIGURES 7–12): Eye with sparse setulae, holoptic, anterointernal facets slightly larger than remaining. Frontal vitta brown with golden pollinosity. Interocular space about 0.07 mm. Fr 10, 7 long and 3 shorts located near the lunule. Fronto-orbital plate and parafacial greyish with greyish pollinosity, bare. Ocellar triangle brown; oc proclinate and developed, one less developed setula on ocellar area. Poc proclinate and less developed. Gena brown with greyish pollinosity, with black setulae. Lunule brown. Antenna inserted below middle height of eyes. Scape brown, 3 setae reaching the pedicel. Pedicel dark brown and with margin yellowish; dorsal setae well developed, 8–9 dispersed short setae. Postpedicel brown with golden pollinosity, 3x the length of pedicel. Arista brown with base yellowish, pubescent. Palpus brown and slightly filiform.

Thorax: General color dark brown to black, golden-brownish pollinosity; scutum with 3 vittae, some piece of the vittae is brown and the other piece is grey, all vittae ending before the base of scutellum. Presutural and postsutural acr setulae in three rows. Dc 2+3. Pprn 4, 2 long and 2 short and strong. Npl 2. Pra 2. Spal 1. Ial 1. Pal 2, the posterior one long and strong.

Wings: Yellowish, slightly darker at costal area. Calypters whitish with margins slightly yellow and pubescent. Halteres light brown at base and whitish at stem and knob.

Legs: Brown and slightly darker at the apices. Pulvillus yellowish. Fore femur with anterior surface setulose; 9 long and strong pv on apical third; 2 rows of p, the lower row with slightly curved apices; 1 row of pd. Fore tibia with 1 preapical d; 1 apical av and pv. Mid femur on ventral surface preapical weakly constricted; 1 row of short a; 1 row of short av, being closer at apex; 1 row of ad; 1 row of long pv, with 4–5 long and strong setae at apex; 1 row of long and thin p with hooked apex. Mid tibia constricted ventrally from the base to the middle; ventral surface covered with short setulae and 1 long apical v; 1 long on apical third a and 1 apical a; 1 long preapical ad; 1 long submedian p. Hind coxa with 2 setae on posterior margin. Hind femur (Figs, 18, 30) on anteroventral to posteroventral surfaces with weak preapical protuberance; 3 rows of short a; 1 row of long av that increase in length apically; 2 short and strong p at base, without setae in the apical quarter; 1 row of small and weak pv, 5–7 long and thin pv on the protuberance; 1 long and strong preapical d. Hind tibia weakly constricted at base; 2 long a on apical third and 1 apical a; 4 long av, 1 strong apical av; v and p surface covered with short setulae; 1 long median d; 1 preapical ad.

Abdomen: Syntergite 1+2 with base brown, with a set of long lateral setae; tergites 3–4 translucent-yellow with media vitta brown, expanded laterally on apical margin of each tergite without reaching lateral region; tergite 5 brown-grey pollinosity with media vitta brown to apical margin. Tergites 3–5 setulose laterally, with long and developed setae. Sternite 1 bare. Sternite 5 wider than long, V-shaped, covered with thin and short setae on posterior margin and with long setae at margin laterally and apex ( Fig. 39View FIGURES 37–42).

Terminalia ( Figs. 46View FIGURES 43–48, 63View FIGURES 62–66, 68View FIGURES 67–71): Epandrium longer than wide, with long and strong setae up to basal half, with short lateral setae; cercal plate longer than wide, V-shaped, weakly fused, rounded apically, uniformly with long setae; surstylus short, articulated with epandrium, with inner median projection sclerotized, distally thin, almost straight apically, shaped as a comma in lateral view with acute apex; bacilliform process present, cuneiform; hypandrium and associated structures as in Fig. 68View FIGURES 67–71.

Female: Unknown.

Biology: According to label data, Fannia copacabana  sp. nov., is associated with decomposed organic matter in secondary forests and synanthropics environments between at 1417–1929 m.

Comments: The male of Fannia copacabana  sp. nov. is morphologically similar to Fannia flavicincta (Stein)  and Fannia katios (Grisales & de Carvalho)  . However, Fannia copacabana  sp. nov. can be distinguished by the color of the palpus (brown to dark brown), eyes with sparse setulae and by the inner basal projections on the surstylus. The surstylus of Fannia copacabana  sp. nov. has inner basal projections, a character shared with the species of the hirticeps group, which have a Nearctic and Palearctic distribution ( Chillcott 1961). Fannia copacabana  sp. nov. also has characters of the heydenii  group, such as bacilliform process cuneiform, hind coxa ciliated on posterior surface and the shape of cercal plate (longer than wide) ( Albuquerque et al. 1981). Until a cladistics analysis is performed it is not possible establish to which species group Fannia copacabana  sp. nov. belong.

Etymology: The epithet of the species refers to the name “Copacabana” (Antioquia, Colombia), where the holotype was collected. A name in apposition.
