Diagnosis. these characters apply only to the male sex. Hind femur on posteroventral surface with pre-apical protuberance and 1 row of long setae ending on the protuberance, where they are developed and have hooked apices, a set of dense v on basal half that become scarcer and run towards the posteroventral surface, 1 row of long av on basal half and 1 row of short av on apical third; hind tibia with 1 row of 6–7 ad and 2 median av.

Gena weakly brown greyish pollinose. Scape black, golden-brownish pollinose on apical margin, with a short and weak seta. Pedicel brown, golden-silver pollinose, apical margin weakly yellowish, with dorsal setae short. Postpedicel golden pollinose, 2.5 times the length of pedicel. Arista brownish with basal third lighter in color; pubescent. Palpus brownish and weakly claviform.

Thorax: brown-greyish; scutum brown, without vittae, golden pollinose up to second postsutural dc and last row of postsutural ac; grey up to base of scutellum, on notopleural region, postpronotum and pre-sutural area; scutellum brown up to discal area and grey on apex. Acr 3:3, not arranged in rows. Dc 2:3. Pprn 3 developed and 1 weak. Pra 2, short, and near spal. Prepm without ground setulae. Pre-basal scutellar area with few ground setulae. Subapical scutellar setae absent. Three discal scutellar setae. Lateral scutellar setae absent.

Wing: yellowish. Calypters whitish with yellow margin. Haltere whitish with base brownish.

Legs: light brown with apex of femora, base and apex of tibiae slightly yellowish, mid trochanter yellow, tarsi light brown and pulvilli yellowish. Fore femur with 1 row of sub equal pd; two rows of p that increase in length on apical half, upper row more developed; 1 row of pv ending in 2 longer setae, 2 long pre-apical pv and 2 short apical pv. Fore tibia with 1 row of short d ending with a pre-apical seta; 1 row of short ad; 1 short apical v. Fore tarsus with basal v strong on first tarsomere. Mid femur constricted on pre-apical ventral surface; 1 row of short ad on basal half and 2 long and curved pre-apical d; 1 row of short v on basal half, 5 short and strong setae on apical half and 2 setae on basal third; 1 row of short and spaced pv on basal half and 2 rows of short and strong setae on apical half, forming a ctenidium; 1 row of p with hooked apices and 5 long and strong setae with straight apices on apical half. Mid tibia on basal half of ventral surface constricted; 1 double series of v on apical half and single series on basal half, 1 strong and long apical v; 1 series of short ad ending in 1 long pre-apical; 1 short a on edge of apical third and 1 apical; 1 short apical v; 1 median p and 2 short pre-apical; 1 short apical pv. Hind coxa with 2 setae on posterior margin.

Biology. according to collecting data, Fannia embera sp. nov. may be a hemi-synanthropic species, associated with humans and forest environments.

Comments. the Pacific Colombian littoral, type-locality of the species, borders Panama and therefore the flora and fauna of Central America. In this region it is possible to find very humid and well preserved tropical forest. This species belongs to the sub-group pusio of the canicularis group.

Etymology. name in apposition. The species epithet refers to the indigenous people Ember, who inhabited several regions of Colombia, including the region of Choc, type-locality of the species. The word “ Emberá ” means “the corn people.

Type material. Holotype male ( CEUA). Colombia. Chocó. Jobí. Chagualito\ Patio de casa.0 m.\ VSR pescado [Van Someren–Rydon trap with fish] \ Agosto 1–2/ 2006 \ P. Duque and M. Wolff. CEUA. Paratypes: Colombia. Chocó. Jobí. Chagualito\ Patio de casa.0 m.\ VSR pescado [Van Someren–Rydon trap with fish] \ Agosto 1–2/ 2006 \ P. Duque and M. Wolff. CEUA (1 male, CEUA); Colombia. Chocó. Jobí. Chagualito\ Patio de casa. 0 m.\ VSR pescado [Van Someren–Rydon trap with fish] \ Agosto 1–2/ 2006 \ P. Duque and M. Wolff. CEUA (26 females, CEUA; 2 females DZUP). The holotype lacks the abdomen, which had been previously dissected for analysis of the terminalia. The rest of the specimen is in good condition.
