Upper and lower orb present, both reclinate. 1 row of short fro, not uniform. Fronto-orbital plate shiny black, not pollinose.

Pedicel with 1 short seta; postpedicel 3 times the length of pedicel. Scutum copper; intra-alar and supraalar postsutural areas and lateral margin of scutellum black. Calypters yellowish; haltere whitish with base yellowish. Legs with tibiae on apical area orange. Fore femur with 1 row of short pv that increase in length slightly towards the apex; 1 row of subequal pd. Fore tibia without av. Mid femur with 1 row of short av that decrease in length on apical half; 1 row of short pv that decrease in length slightly towards the apex. Mid tibia without basal ventral constriction; 1 long apical v; 2 short p on edge of apical third. Hind femur with slight ventral apical constriction, flattened on anterior and posterior surfaces; 1 row of short ad increase in length slightly on apical half; av developed and spaced on apical half; p short on basal half; ventral surface naked. Hind tibia with median 1 av. Abdomen not trimaculate, copper-brown; tergite 4 with 1 pair of median lateral setae. Terminalia (Fig. 132): cercus slightly longer than hypoproct, with long setae, and sinuous at apex; hypoproct round, with setae mainly on apical region and shorter than cercal setae; sternite 8 reduced to separated plates and with long, developed and sinuous setae; sternite 7 wider than long and with setae on apical half, being longer than the apical most setae; sternite 6 larger than sternite 7 and with apical setae unordered; 2 semicircular spermathecae apically flattened.

Biology. according to collecting data Fannia chibcha sp. nov. is widely distributed, being found in forests from medium altitudes (1050 m) up to high and cold ridges (2800 m). The species was collected mainly from pig carcasses, and can be considered of forensic relevance in the region.

Comments. the male of Fannia chibcha sp. nov. is similar to male of F. parafemoralis Araujo and Couri, 1996 , but F. c h i b c h a can be easily diagnosed by the strongly curved hind femur, the facial chaetotaxy, av and pv strongly developed on apical half.

The male of Fannia chibcha is similar to male of F. yunguensis Quiroga & Domínguez, 2010 , but differs from it in the number of fro setae (18 pairs), sparse setulae on eyes, yellowish wing, hind coxa with 4 setae on posterior margin, hind tibia with 1 row of 9–13 a on apical half, abdomen trimaculate, and female sternite 8 (separate plates) with more developed and sinuous setae. Fannia chibcha sp. nov. belongs to the sub-group pusio of the canicularis group ( Albuquerque et al. 1981; Couri 2005).

Etymology. Name in apposition. The species epithet refers to the pre-Colombian indigenous Chibcha , who inhabited the high grounds of the cundiboyacense highlands in Colombia, type-locality of the species.
