( Figs.1M , 4 J–K, 5M, 7E, 8M) Diagnosis . Fore tarsus with tarsomeres 3–5 flattened, tarsomere 1 and 2 yellowish on part of v surface. Description. Holotype male ( Fig. 1M ) Head: eye slightly setulose. Frontal vitta velvety black, pollinose. 12 fr . Ocellar triangle black; oc proclinate and developed, 3 less developed setulae on ocellar area. Fronto–orbital plate silver and pollinose. Parafacial bare, silver pollinose. Fronto–genal suture and gena silver pollinose, gena with long setae. Scape black, 2 setae reaching pedicel. Pedicel black pollinose with a dorsal seta developed and surrounded minor setae. Postpedicel black, golden silver 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 2:2–3 arranged in rows. Dc 2:3, long, posterior most postsutural pair developed. Pprn 4, developed. Pra 2. Pro–epimeron setulose. Wing: brownish, with upper third between vein C and half of cell r 2+3 darker. Calypters whitish. Haltere brown with stem and base lighter in color. Legs: black, pulvilli brownish and tarsi black, except for fore tarsomere 1 and 2 with part of them yellowish on v surface. Fore femur setulose on posterior surface with 1 row of long pv and d . Fore tibia with 1 strong pre–apical d ; 1 apical pv ; 1 apical p ; 1 apical v . Fore tarsomere 1 and 2 yellowish on part of v surface; tarsomeres 3–5 flattened ( Fig. 4J ). Mid femur with 2 rows of long pv , hooked apices on apical third and 1 row of developed av decreasing to the apex. Mid tibia on ventral surface with pronounced constriction on basal half area, densely setulose on apical half, 1 v ; 2 median ad ; 1 d ; 2 p ; 1 apical pv ; 1 pd . Hind coxa bare on posterior margin. Hind femur on ventral surface with pre–apical protuberance; av , v and p surfaces setuloses, av setae longer and curved, increasing in size from base to apex ( Fig. 4K ). Hind tibia with 1 median d and 1 pre–apical; 1 median a ; 1 median av and 1 apical ( Fig. 4K ). Abdomen: elongate, black, weakly greyish pollinose with developed setae. Sternite 1 densely setulose. Sternite 5 ( Fig. 5M ). Terminalia ( Fig. 7E ): epandrium wider than long, with apical hook extensions; cercal plate pointed apically, base fused almost completely; surstylus strongly articulated with epandrium, pointed apically; bacilliform process spiral and short near epandrium extensions. Female : unknown. Biology . Label information indicates that this species occurs in the Andean highlands in Ecuador , from 2500 m in the western foothills. Nothing else is known about its habits or biology. Comments . Fannia tsachilas sp. nov. is morphologically similar to Fannia iguaque , F. chingaza and F. sutagao described by Grisales, Wolff and Carvalho (2012), due to the fore tarsomeres 3–5 flattened, but differs in the hind femur and the terminalia. Etymology . Name in apposition. The species epithet refers to the Tsachilás indigenous people, from Ecuador . Type material. Holotype male (MZSP). ECUADOR : N. Latacunga / Ecuador , 3300m ./ XII.1970 / L. E. Peña Leg / MZSP. Paratypes . ECUADOR . Latacunga : N. Latacunga / Ecuador , 3300m ./ XII.1970 / L. E.

Perucho / Otavalo 2000 m ./ Ecuador. I. 1971 / L. E. Peña col./ MZSP ( 1 male , MZSP ) . The holotype has no abdomen because it was taken to dissect the terminalia and it was fixed under the holotype . Distribution . Ecuador : provinces of Cotopaxi , Loja , Santo Domingo de los Tsáchilas and Imbabúra (Andean region) ( Fig. 8M ).
