Diagnosis: these characters apply only to the male sex. Eye holoptic and with sparse short setulae, poc divergent; calypters whitish; fore femur with 1 row of long and strong pv; mid tibia with 2 apical a, 1 median and 2 apical p; hind femur on ventral surface with weak preapical protuberance, with a tuft of thin setae from ventral to posterior surface of the protuberance; hind tibia with 3–4 median av; surstylus on ventral surface on basal third with a projection with 5–7 spines directed inward; terminalia with hook-shaped bacilliform process.

Male Measurements: 4.49–5.39 mm (body length); 3.52–5.29 mm (wing length).

Head ( Figs. 6 View FIGURES 1–6 , 12 View FIGURES 7–12 ): Eye with sparse setulae and holoptic, antero-internal facets slightly larger than remaining. Frontal vitta black, black to golden pollinosity. Interocular space about 0.06 mm. Fr 16–19, long. Fronto-orbital plate and parafacial black with greyish pollinosity, bare. Ocellar triangle black; oc proclinate and developed, 2 less developed setulae on ocellar area. Poc divergent. Gena black, with some black setulae. Lunule black. Antenna inserted below middle height of eyes. Scape dark brown, black pollinosity, 2 setae reaching the pedicel. Pedicel black, brownish pollinosity; dorsal seta short and stout, with 5 short setae. Postpedicel black, golden pollinosity, 2.5– 3x the length of pedicel. Arista dark brown, pubescent. Palpus dark brown and filiform.

Thorax: General color black to dark brown. Presutural and postsutural acrostichal setulae in 3 rows. Dc 2+3. Pprn 2, long and strong, almost of the same size. Npl 2. Pra 2. Spal 1. Ial 1. Pal 2.

Wings: Brownish, with the upper third between C and half of R 2+3 veins darker. Calypters whitish with margins slightly darker. Halteres light brown at base, whitish at stem and dark brown at knob.

Legs: General color black to dark brown. Pulvillus yellowish. Fore femur setulose on anterior surface; posterior surface with long unordered setae, 1 row of long and strong pv and pd, both longer than p. Fore tibia with 1 on apical third ad; 1 preapical d, 2x the length of ad; 1 short and strong apical p; 1 apical v. Mid femur on preapical ventral surface weakly constricted; 1 row of ad, 3–4 stronger setae on apical third; 1 row of long and strong av, setae widely separated on basal half, and forming a weak ctenidium on apical third; 1 row of long p and pv, become stronger again the apex, with hooked apices; dorsal and posterior surface with sparse setulae. Mid tibia constricted on basal ventral surface; 2 apical a; 1 median ad; 1 apical pv; 1 median p and 2 apical; 1 preapical d; ventral surface covered with short and inconspicuous setulae, longer at the apical half. Hind coxa with 3–5 setae on posterior margin. Hind femur ( Figs. 21 View FIGURES 17–28 , 33 View FIGURES 29–36 ) on ventral surface with weak preapical protuberance, conspicuous tuft of thin setae from ventral to posterior surface of the protuberance, with slightly curved apex; 2 rows of a that increase in length apically, one going towards anteroventral edge and the other going towards the anterodorsal edge; 2 rows of p, the basal longer than the remaining. Hind tibia with 1 long and strong a; 3–4 long median av; 1 row of short ad with 1 long setae on apical third; 1 long and strong apical v; 1 preapical d.

Abdomen: Elongate, black. Tergites 3–5 with brown lateral marks. Syntergite 1+2 with thin setae over the entire surface. Tergites 4–5 setulose laterally, with 2 pairs of long and developed setae. Sternite 1 densely setulose. Sternite 5 wider than long, V-shaped, covered with setulae on posterior margin, with stronger setae at apex ( Fig. 42 View FIGURES 37–42 ).

Terminalia ( Figs. 60, 61 View FIGURES 55–61 , 66 View FIGURES 62–66 , 71 View FIGURES 67–71 ): Epandrium wider than long, with long and strong setae up to basal half; cercal plate longer than wide, V-shaped, fused, rounded apically, uniformly setulose; surstylus laterally articulated with epandrium with visible articulation, long, slightly shorter than epandrium, distally thin, almost straight apically, shaped as a comma in lateral view with rounded apex, ventral surface on basal third with a projection with 5–7 spines of different size, directed inward ( Fig. 61 View FIGURES 55–61 ); bacilliform process present, hook-shaped; hypandrium and associated structures with a trident-shaped as in Fig. 71 View FIGURES 67–71 .

Female: Unknown.

Biology: According to label data, Fannia spinosa sp. nov., is associated with decomposed organic matter in secondary forests and synanthropics environments between at 1840–1943 m.

Comments: Fannia spinosa sp. nov. can be easily separated from the remaining species of Fannia known by the projection with 5–7 spines on ventral surface of the surstylus. The male of Fannia spinosa sp. nov. is close to Fannia hirtifemur (Stein) but differs in the shape of bacilliform process. The combinations of characters of this species make it difficult to include it in any known group of Fannia .

Etymology: The species epithet, spinosa , refers to the ventral spines of the surstylus, characteristic of this species. Noun in apposition.
