Fannia polleti View in CoL sp. nov.

( Figs. 1I View FIGURE 1 , 3 View FIGURE 3 O–P, 5I, 7A, 8I)

Diagnosis. Wing brownish, with upper third darker, fore tarsomeres 3–5 flattened, hind coxa bare on posterior margin, hind femur strongly curved, ventral surface with strong pre–apical protuberance extending over anterior and posterior surfaces.

Description. Holotype male ( Fig. 1I View FIGURE 1 )

Head: eye densely setulose. Frontal vitta velvety black, brownish pollinose. 15 fr. 1 pair of oc proclinate and developed, 5 less developed setulae on ocellar area. Fronto–orbital plate black, greyish pollinose. Parafacial bare, narrowing ventrally, greyish pollinose. Oral margin projecting anteriorly. Fronto–genal suture with brownish hairs. Gena black, yellowish pollinose. Scape black, 3–4 short setae reaching pedicel. Pedicel black pollinose, dorsal setae developed. Postpedicel black, brownish pilose, 2 times the length of pedicel. Arista black, with short pubescence, rays shorter than width of base of arista. Palpus black and filiform.

Thorax: black. Scutum without vittae. Acr 2:3–4, not arranged in rows. Dc 2:3, long, posterior most postsutural pair developed. Pprn 4, 3 developed and 1 weak. Pra 2, strong. Pro–epimeron setulose. Pre–basal scutellar area with ground setulae.

Wing: brownish, with upper third between C vein and half of R 2+3 vein, and cells br, bm and cup darker.

Legs: black with tarsi black and pulvilli brownish. Fore femur with 1 row of long d; a and av inconspicuous; ventral surface bare; 1 row of long pv with straight apices; posterior surface setulose, with long and weak setae with curved apices. Fore tibia with 1 strong pre–apical d; 2 short ad; 1 apical pv; 1 median p and 1 apical; 1 apical v. Fore tarsus with 1 strong and thin v on first tarsomere; tarsomeres 3–5 flattened ( Fig. 3O View FIGURE 3 ). Mid femur constricted on pre–apical ventral surface; 1 row of short ad; 1 row of strong av that decrease in length towards apex; 1 row of long pv with hooked apices, setae decrease in length towards apex; 1 row of weak p with 6 longer on apical third. Mid tibia on ventral surface with pronounced constriction on basal half area, densely setulose on apical half, 1 long and strong apical v; 1 developed pre–apical ad; 1 developed a on mid apical half and 1 apical; 1 developed apical av; 1 apical pv; 2 p. Hind coxa bare on posterior margin. Hind femur strongly curved; ventral surface with strong pre–apical protuberance extending over anterior and posterior surfaces ( Fig. 3P View FIGURE 3 ); 1 row of ad, 4 setae running towards dorsal surface ( Fig. 3P View FIGURE 3 ); anteroventral surface setulose, with setae that increase in length to pre–apical protuberance; protuberance with tuft of long setae with hooked apices; posteroventral and posterior surfaces weakly setulose. Hind tibia with 1 developed median d and 1 pre–apical; 1 long and developed median ad at the same level of d; 1 short apical a; 1 median av, 1 apical.

Abdomen: elongate, black, weakly greyish pollinose and long and with developed setae. Sternite 1 densely setulose. Sternite 5 ( Fig. 5I). Terminalia ( Fig. 7A View FIGURE 7 ): epandrium wider than long, with short apical internal projections and a few fine setae on apical half; cercal plate elongates apically, with short weak setae mainly on the basal third; surstylus articulated with epandrium, curved apically, shaped as a comma in frontal and lateral views, basal half broad; bacilliform process spiral and simple.

Female: unknown.

Biology. Label information indicates that this species occurs in the Andes in southern Ecuador, above 3000 m. Nothing else is known about its habits or biology.

Comments. Fannia polleti sp. nov. is morphologically similar to Fannia chingaza Grisales, Wolff & Carvalho, 2012 from Colombia. Fannia polleti sp. nov differs on the hind femur (with a tuft of more developed setae on preapical protuberance in F. chingaza ) and the fore tarsomere (less flat in F. chingaz a) and the shape of the tip of the cercal plate (square in F. chingaz a).

Etymology. Name in apposition. The species epithet is in homage to Marc Pollet, a researcher who collected a lot of interesting Diptera material in and near Podocarpus National Park (southern Andes, Ecuador) in 2009.
