( Figs 70–76 ) Diagnosis . Tergite 1, anterior margin of tergite 2, tergites 6–7 yellow. Cercus narrow basally, curved medially, bifid at apex ( Fig. 73 ); hypandrium narrower and bifid apically ( Fig. 76 ); phallus sclerotized, with small membranous area apically ( Fig. 75 ). Description . Male ( Fig. 70 ). Head . Dark brown to black, antenna and mouthparts yellow with all setae whitish; ocellar triangle with 1 pair of proclinate setae; anterior ocellus larger. Eyes iridescent black, very narrowly separated on face which bears fine reclinate setulae. Frons with 1 pair setulae; 2–3 pairs of vertical setae contiguous with uniseriate postocular setae; occiput bearing scattered fine hairs. Clypeus with rather dense short downwardly directed pile. Proboscis slightly curved with setae yellow. Antenna with scape and pedicel bearing distinct short dorsal setulae; postpedicel about 1.5X as long as wide, stylus ~ 0.8X as long as postpedicel. Thorax ( Fig. 70 ). Yellow, short, arched ventrally; antepronotum with anterior margin almost straight and scutum with yellow setae, very small and fine except 1 notopleural. Legs ( Fig. 70 ). Whitish yellow. C1 ~ 1.2X longer than distance between C1 and C2, 5X as long as wide with some pale dorsoapical setae. F1 about the same length as C1, 4.0–4.5X as long as wide; femoral formula 5–6/20–21/1+18–19/7–8; denticles confined to distal 0.8, becoming closer together distally, black, 2 rows linear, without distal discontinuity. T1 ~ 0.7X as long as F1, evenly curved, ventral face shallowly concave; with 2 rows of 19–21 sharply pointed spinose setae ventrally; dorsal ciliation of decumbent short pale setulae, denser distally; without apicoventral extension on T1 but with strong apical spine. Mid and hind legs slender with fine setae but T3 with ‘comb’ of short setae posteroapically. Wing ( Fig. 70 ). Membrane faintly yellow, veins brownish; R2+3 long and straight, not strongly curved towards C apically,,joining C ~ 0.6 distance between end of R1 and R4; R4+5 fork angle acute (~ 60°), distal to position of M1+2 fork by ~ 1.5X as long as R4; R5 and M1 convergent distally and diverging at extreme apex; vein R5 ~ 1.5X as long as R4; cell bm+dm short, ending at level of R1, ~ 2.0X as long as cell br. Halter whitish yellow. Abdomen ( Figs 70, 71 ). Tergites with posterior margin of sclerites 2, 3–5 and 8 brownish; tergite 1, anterior margin of tergite 2, tergites 6–7 and sternites yellowish. Tergites 7–8 with pale strong setae laterally on posterior margin; tergite 8 as long as sternite 8. Terminalia . Brownish. Cercus narrow basally, curved medially, bifid at apex ( Fig. 73 ), with very strong inwardly directed setae apically on lower lobe. Epandrium wide, with scattered setae on outer face ( Fig. 73 ). Surstylus simple, with distinct setae apically ( Fig. 74 ). Hypandrium narrower and bifid apically, without distinct setae; gonocoxal apodeme confined to anterior margin of hypandrium, lacking narrow process. Subepandrial sclerite concave posteriorly, without posterior process. Phallus sclerotized basally, extending beyond hypandrium apex, with small membranous area apically ( Fig. 75 ). Ejaculatory apodeme absent. Body length : 1.9 mm ; wing length : 1.7 mm . Female : Unknown. Type material . HOLOTYPE ♂. “BR[asil], AM[azonas], Manaus. R.[eserva] Ducke. IG.[arapé] Bolivia .

Holotype condition . Good. Not dissected. Etymology . The specific name is in tribute to K.G.V. Smith due to his contribution to the knowledge of the Neotropical fauna of Empididae , especially that of Brazil . FIGURES 70–76 .
