Wing: brownish, with upper third between C vein and half of vein R2+3, base of cell br, bm and cup darker. Calypters whitish with margin of upper calypter brown. Haltere brown, with stem base lighter in color.

Legs: brown with tarsi dark and pulvilli brown. Fore femur with 1 row of weak av up to median third; 1 row of long pd; posterior surface densely setulose, with long and strong setae; 1 row of long pv and with straight apices. Ventral surface bare. Fore tibia with 1 pre-apical d; 1 ad on edge of apical third; anteroventral and ventral surfaces densely setulose from median third to apex, with short setae; 1 pd on edge of apical third and 1 pre-apical; 1 preapical pv; 1 apical v. Fore tarsus with 1 strong v on first tarsomere followed by a thin seta; tarsomeres 3–5 flattened and widened ( Fig. 131 View FIGURES 128 – 131 ). Mid femur constricted on pre-apical ventral surface; 1 row of av decreasing in length on basal third where they are more ventral; 1 row of short a ending in longer seta; 1 row of long p up to median third; 1 row of strongly developed pv with hooked apices, ending in 4 longer p; 1 row of v on basal third, shorter than the pv. Mid tibia on basal half of ventral surface with more pronounced pre-basal constriction, and dorsal surface densely setulose on apical half medially, 1 apical long v, strong and bifid; 1 pre-apical a; 1 developed on edge of apical third and 2 pre-apical ad, one long and one short, developed; 1 developed pre-apical d; 1 pd on edge of apical third and 1 pre-apical, strong and long d; 2 developed pre-apical p. Mid tarsus with 1 short v on first tarsomere. Hind coxa on posterior margin bare, with setae on ventral margin that can be confused with setae on posterior margin. Hind femur strongly curved, on ventral surface with pre-apical conspicuous protuberance, with developed av and v tufts, v with curved apices ( Fig. 36 View FIGURES 20 – 37 ); 1 row of long ad on apical half; ventral surface on basal half setulose; 1 long p with curved apex and 2 shorter, basal half setulose; 1 row of pv on apical third, not uniform, and developed ( Fig. 54 View FIGURES 38 – 55 ).

Female: unknown

Biology. According to label data, Fannia sutagao sp. nov. is associated with cold ecosystems of the Páramo (up to 3000 m) and occurs at the Parque Nacional Natural Sumapaz . This ecosystem is characterized by an abundance of water bodies, grasses 40–50 cm long, “frailejón (Asteracea, Espeletia ) and a high diversity of plant and animals (Parques Nacionales Naturales 2002).

Comments. these characters apply only to the male sex. Fannia sutagao sp. nov. is morphologically similar to F. iguaque sp. nov. and F. sumapaz sp. nov., but differs in the strong protuberance on the hind femur, a tuft of developed setae on the protuberance, and a tuft of strong setae on tergite 5 crossing above the terminalia.

Etymology. Name in apposition. The species epithet refers to the name the Spaniards gave to the Páramo de Sumapaz , “Páramo de los Sutagaos. This is due to the group of indigenous people who controlled the territory.

Type material. Holotype male (IAvH).CO [ Colombia]. Meta. P.N.N [Parque Nacional Natural] Sumapaz .Bocatoma\ Cerro El Zapato. 4˚14’N 74˚12W\ 3560 m. Malaise 2–17.i.2003 \ A. Patiño \ Leg. M.3442. IAvH. Paratype: CO [ Colombia]. Meta. P.N.N [Parque Nacional Natural] Sumapaz . Bocatoma\ Cerro El Zapato. 4˚14’N 74˚12W\ 3560 m. Malaise 2–17.i.2003 \ A. Patiño \ Leg. M.3442. IAvH (1 male, IAvH). The holotype is a little crushed; the frontal setae and tarsi of both hind legs are missing.
