Diagnosis. these characters apply only to the male sex. Hind femur with 1 row of long apical pv that become longer, form a tuft of setae on pre-apical protuberance and have apices slightly curved, ventral surface setulose, 2 rows of weak av ending on pre-apical protuberance and 1 long pre-apical av; hind tibia with 1 row of 5 a and 1 median av.
Description. Holotype male: body length: 4.2 mm; wing length: 3.4 mm.
Head: eye with sparse setulae. Frontal vitta velvety black. Interocular space 0.04 mm. Fr 11 ( Fig. 16 View FIGURES 13 – 19 ). Ocellar triangle grey pollinose, weak; oc proclinate and developed and 5 less developed setulae on ocellar area. Poc divergent. Fronto-orbital plate and parafacial greyish pollinose. Parafacial with short setae beginning at point of insertion of scape. Gena black, weakly grey pollinose. Lunule black. Scape black greyish pollinose, on apical margin with 1 short seta. Pedicel black, weakly grey pollinose and short dorsal setae. Postpedicel greyish pilose, 3 times the length of pedicel. Arista brown pubescent. Palpus dark brown, slightly claviform.
Thorax: grey, scutum without stripes and dark brown up to ia posterior area, grey up to base of scutellum and on notopleural region and pre-sutural area, scutellum brown on basal half. Acr 3:3–4, irregular, not arranged in rows. Dc 2:3, last pre-sutural pair developed. Postpronotum with 2 developed setae, weak. P ra 2, short. Proepimeral area without ground setulae. Pre-basal scutellar area with less developed ground setulae. Subapical scutellar setae absent. Discal scutellar setae 1 pair.
Wing: yellowish with tegula brown; basicosta, subcostal sclerite, stem vein and auxiliary sclerites yellow. Calypters yellowish with margins yellow. Haltere whitish with base yellowish.
Legs: brown with apical margin of femora and tibiae weakly yellowish, tarsi brown and pulvilli yellowish. Fore femur with 1 row of short av; 1 row of short pv that increase in length on apical half; 5 p on basal half and 1 row of setae on apical half. Fore tibia with 1 short pre-apical d; set of short apical v. Mid femur on pre-apical ventral surface constricted; 3 pre-apical ad; 1 row of short av, sparse and strong, decreasing in length towards apex; 1 row of pv forming a ctenidium on apical third; 1 row of p ending in 4 more developed apical setae. Mid tibia on ventral surface with weak basal constriction and 2 apical v, one long and one short; 1 a on edge of apical third, and 1 short apical a; 1 pre-apical d; 1 median pv and 1 apical, short. Hind coxa with 2 setae on posterior margin. Hind femur on ventral surface with pre-apical protuberance ( Figs. 32 View FIGURES 20 – 37 , 50 View FIGURES 38 – 55 ); ventral surface setulose; 1 row of long a ending in 3 longer setae on pre-apical protuberance; 2 rows of weak av, ending on pre-apical protuberance, 1 long pre-apical; 1 row of ad ending in 4 d; 1 row of long pv on apical half that increase in length and form a tuft on preapical protuberance, apical setae slightly curved ( Fig. 50 View FIGURES 38 – 55 ). Hind tibia with 1 median and 1 pre-apical d, long; 1 row of 5 a, 1 on edge of apical third and 2 pre-apical ( Fig. 32 View FIGURES 20 – 37 ); 1 median and 1 apical short and strong av. Hind tarsus with a set of short and strong basal v on first tarsomere; apical tarsomere slightly widened.

Terminalia ( Figs. 86 View FIGURES 83 – 91 , 104 View FIGURES 101 – 109 ): epandrium wider than long, with weak setae on epandrium, one pair of developed apical setae; cercal plate V - shaped and separated apically, with weak setae mainly on basal and lateral areas; surstylus fused with epandrium, with lateral-ventral projections with apical setae, inner basal region setulose and with short setae on apex; bacilliform process absent; hypandrium and associated structures as in Fig. 122 View FIGURES 118 – 127 .
Female: unknown.
Variation: male: 10 fr, base of haltere brown, mid femur with 1 row of p ending in 6 apical developed setae, hind tibia with 1 row of 6 ad.
Biology. According to label data, Fannia porce sp. nov. is associated with decomposing organic matter, in forests and in rural areas in lowlands of the Central Cordillera (770-1050 m).
Comments. These characters apply only to the male sex. Fannia porce sp. nov. is morphologically close to Fannia sabroskyi Seago , but differs in the more developed a, av and pv on the hind femur. Both species belong to the sub-group pusio of the canicularis group.
Etymology. Name in apposition. The species epithet refers to the Porce River, an extension of the Medellín River, department of Antioquia, type-locality of the species.
