Type material. Holotype: Male. “Cocun \ PNN Sumapaz/ Bocatoma Cerro El Zapato \ 4° 14’ N; 74° 12’ W \ 3560 msnm \ Malaise \ Nov 6-7/ 2002 \ IAvH (white printed label)” (IAvH)GoogleMaps . Paratypes: 1 female. Same data as holotype (IAvH).
Additional examined material. Three females, same data as holotype (IAvH).
Description. Coloration. Ground color grey. Frons and fronto-orbital plate dark brown. Parafacial and gena grey pollinose. Ocellar triangle dark brown. Antenna, arista and palpus dark brown. Mesonotum brown. Pleurae grey. Calypter whitish. Halter yellowish. Wing light brown. All legs grey, femora weak brown pollinose in the apex. Abdomen grey with brown pollinose on center areas of tergites 2–5.
Male. Body length: 4 mm (holotype).
Head ( Figs 1B, DView FIGURE 1). Ocellar triangle narrow, extending to the ptilineal suture. Five pairs of frontal setae; upper orbital seta only one pair; ocellar setae well developed; postocellar setae same length as ocellar pair; inner convergent and outer divergent vertical setae shorter than ocellar setae. Antennae ( Fig. 1BView FIGURE 1). Postpedicel measuring about 1.5 length of pedicel. Arista long, larger on basal fourth, shortly pubescent.
Thorax ( Fig. 1CView FIGURE 1). Postpronotal lobe, presutural scutum, postsutural scutum and scutellum with a few setulae. Acrostichal pre-sutural setae differentiated, arranged in four pairs of setae; intralar setae 1+2; basal postpronotal setae 2; supra-alar setae 1+1; intrapostalar seta developed. Notopleuron with 2 similar setae, without cilia covering it. Scutellum with sub-basal and an apical pair of strong setae. Prosternum bare; proepisternum, proepimeron bare; anepisternum setulose near notopleuron; anepimeron bare; katerpisternum and katepimeron bare; meron bare.
Wing. Long, slender, anal lobe weakly developed. Vein R 4+5 and M 1 parallel on apical part; vein dm-cu almost straight; vein CuA 2 +A 1 short; vein A 2 long and weak.
Legs ( Fig. 7View FIGURE 7). Fore femur with d, pv, p and pv complete rows of setae. Fore tibia with a median p setae well developed and 3 apical setae (d, pd and pv). Mid femur with irregular ad, av and v rows of setae, longer on apical half and 2 pre-apical setae on pv surface. Mid tibia with 1 median seta on d and ad and 5 apical setae (d, pv, p, v and av). Hind femur with irregular ad, av and pv rows of setae, longer on apical half.
Abdomen ( Figs 1A, CView FIGURE 1). Longer than thorax. Tergites I–IV with developed lateral setae at disc and apex, tergites IV and V with a complete row of setae at disc and apex. Sternite 5 setulose, more concentrated on the lobes ( Fig. 2AView FIGURE 2).
Terminalia ( Figs 2View FIGURE 2 B–E). Epandrium large and divided in the center; cercus setulose, longer than wide ( Fig. 2EView FIGURE 2); surstylus long, about the same length of cercus ( Fig. 2CView FIGURE 2). Phallic complex: hypandrium short tubular; praegonite long, longer than wide; postgonite short with membranous apex; epiphallus long and curved; distiphallus membranous on apex; phallapodeme long and curved on apex ( Fig. 2DView FIGURE 2).
Female: Body length: 4.2 mm.
Similar to male.
Terminalia ( Figs 4View FIGURE 4 A–C). Ovipositor long with microtrichia on sternites 6, 7 and 8; segment 8 without spicules; cerci medium to long and slender; segments 6 and 7 not fused; epiproct well developed; hypoproct not modified, setulose, at most twice as high as wide; tergites 6 and 7 two intermediate to slender plates; 3 spermathecae.
Distribution. The new species is only known from the type locality.
Biology. Unknown. Some authors have discussed characters of the head and mouthparts of muscids. More specifically, Hennig (1965) considered that some characters on the head and mouthparts of flower-visiting species could be associated with their biology. Flower visitors, especially those occurring in high altitudes, tend to have the gena enlarged, resulting in longer parafacials. These characteristic are found in Sumapazomyia inusitata sp. nov.
Etymology. The specific name refers to the strange morphology of the head and mouthparts.
