Mesorhaga funebris Parent (Fig. 1 f) Mesorhaga funebris Parent 1929: 16. Type material. Parent described Mesorhaga funebris based on a male from Peru: Loreto, Iquitos (MLUH, not examined). His description and figures allow this species to be identified with confidence.

Possible Ψ of this species: ECUADOR: PINCHINCHA, Santo Domingo, Rio Palenque Stn., 240 m, 29.vii.1976 (CNC); VENEZUELA: T.F.

Head: major setae black; 3 strong postvertical setae present; strong proclinate vertical present on lateral frons; vertex, frons, face, and clypeus dark metallic blue-green, with orientated silvery pruinosity; clypeus narrowed distally and adjacent to margins of eyes; palp dark brown with strong apical seta; proboscis brown; antenna black; first flagellomere rounded, subrectangular, arista dorsal, about as long as head height; ventral postcranium with abundant whitish setae. Thorax: metallic green with bronze reflections; setae black; pleura with some grey pruinosity; 3 pairs long ac, with shorter paired setulae anteriad; lateral scutellar setae almost half as long as median setae. Legs: all coxae, basal two-thirds of FI, basal five-sixths of FII and all leg III dark brown; distal femora, tibiae, and basitarsi I and II, yellow; distal tarsomeres I and II brown; CI and CII with white anterolateral setae; CIII with strong, white, lateral seta and some shorter setae. I: 4.5; 4.7; 2.5/ 1.0/ 0.6/ 0.4/ 0.5; FI with white av and pv setae; TI bare of major setae; tarsus I unmodified. II: 5.1; 6.0; 3.9/ 1.2/ 0.8/ 0.5/ 0.4; FII with white av and pv setae basally, black in distal sixth; TII bare of major setae except for apicoventral seta. III: 6.2; 7.2; 2.8/ 2.0/ 1.2/ 0.7/ 0.5; FII with white av and pv setae basally, black in distal quarter. Wing: (similar to Fig.1 c); with dark brown cloud over basal and anterior part of the wing, extending posteriad of CuA and beyond the bend in vein M; vein M with gentle, right-angle curve at 1/3 between dm-cu crossvein and wing apex; CuAx ratio: 1.2; lower calypter brown with black rim and fan of black setae; halter stalk brown, club black. Abdomen: terga metallic blue-green, with matt purple bands near tergal overlap; with black vestiture; terga 4–5 with long, black ventral setae near lateral margins; sternum 8 with long setae; hypopygium (Fig.1 f) black; phallus and hypandrium elongate and narrow; long epandrial seta at base of epandrial lobe; epandrial lobe ovate, with strong setae at 1/2 and 3/4; surstylus with long subapical seta; cercus bent at right angle, with some long, lateral setae near base of bend, and distal cercus parallel-sided with apical notch. Female: similar to male except: wing: 2.8–3.0; ocellar tubercle not so prominent; face and clypeus wider than in male; pedicel with much shorter ventral apical seta; 1st flagellomere more rounded; ac absent or with 1–2 pairs short ac present anteriorly; abdominal tergum 1 without posterolateral row of long setae. Remarks. Mesorhaga funebris is known from lowland elevations (less than 400 m) in Amazonian Peru, Ecuador and Venezuela.
