(modified from Evenhuis 2002a)

1 Antenna with one flagellomere ( Fig. 14 View FIGURES 12–20 ). Stylus distal, tiny, inconspicuous (visible only in higher magnification); postcranium produced, subequal to eye length ( Figs 12, 13 View FIGURES 12–20 ).......................................... Tamanduamyia   , gen. nov.

- Antenna with two flagellomeres and stylus placed apically ( Fig. 2 View FIGURES 1–11 ) or subapically on the second flagellomere ( Fig. 21 View FIGURES 21–25 ); postcranium not produced ( Fig. 1 View FIGURES 1–11 )....................................................................... 2

2 Antenna with stylus placed apically on second flagellomere.................................................. 3

- Antenna with stylus placed subapically on second flagellomere ( Fig. 21 View FIGURES 21–25 ).......................................... 4

3 Vein A 1 complete, reaching wing margin ( Fig. 22 View FIGURES 21–25 ); costal vein incomplete, ending between R 4+5 and M 1 veins......................................................................................... Mythenteles Hall & Evenhuis  

- Vein A 1 short, incomplete, reaching alular incision level; costal vein circumambient ( Fig. 3 View FIGURES 1–11 )........... Mitinha   , gen. nov.

4 Costal vein circumambient; cell dm fairly short, closed apically ( Fig. 23 View FIGURES 21–25 )...................... Reissa Evenhuis & Baéz  

- Costal vein incomplete, ending just beyond end of vein R 4+5. Cell dm much longer than wide ( Figs 24, 25 View FIGURES 21–25 ) or open apically. 5

5 Wing with well-developed keel-shaped anal lobe; vein separating basal cells not evident ( Fig. 25 View FIGURES 21–25 ); males holoptic................................................................................................ Mythicomyia   ... 6

- Wing with anal lobe normal, not keel-shaped; vein separating basal cells distinct, often well sclerotized ( Fig. 24 View FIGURES 21–25 ); males dichoptic........................................................................................... 7

6 Males with secondary sexual character modifications on the legs (modified shapes of and notches in mid and/or hind legs and presence of pegs and large setae).......................................... Mythicomyia (Mythicomyia) Coquillett  

- Males without secondary sexual character modifications of legs..................... Mythicomyia (Heterhybos) Brèthes  

7 Wing with cell dm open, distal veins faint or effaced; head as wide as or wider than thorax......... Nexus Hall & Evenhuis  

- Wing with cell dm complete ( Fig. 22 View FIGURES 21–25 ); distal veins not faint; head usually narrower than thorax........... Pieza Evenhuis
