1 Large species (~ 110 mm – ~ 260 mm); long setae present on the integument, abundant on the propodeum; wing fully or partially darkened; wing venation long, 3Rs cell almost touching the apex of the forewing; usually with a prominence on the lower part of the mesopleurum; hind tibia with scale-like spines........................................ Alasagenia Banks  

- Median to small size species (until ~ 110 mm); long setae on integument present or absent; wing usually hyaline or subhyaline; wing venation short, 3Rs cell about its length, or more, distant from the apex of the forewing; never with a prominence on lower part of mesopleurum; hind tibia with or without scale-like spines........................................... 2

2 Head and mesosoma black, metasoma rufous; pronotum elongate and somewhat flat, in profile view, length from the collar to the posterior margin of pronotum larger than its height; hind leg with inner brush distally interrupted........................................................................................ Nemagenia Banks   [ A. longula (Cresson)   ]

- Coloration of integument various; pronotum never elongate, in profile view, length from the collar to the posterior margin of pronotum as long as its height; hind leg usually with inner brush distally continued................................. 3

3 Frons in lateral view somewhat angulate, with swellings above or between the antennal insertion ( A. innuba   lacks distinct swellings)........................................................................................... 4

- Frons in lateral view more or less gently rounded, without swellings above the antennal insertion...................... 5

4 Frons with two large swellings; head black, covered with scale-like setae, except the swellings and the clypeus, which have a polished integument; forewing hyaline with one dark band; mesosoma red, metasoma black...................................................................................... Neotumagenia Fernández   [ A. amazonica Fernández   ]

- Frons with or without swellings, but never as large as described previously; head never covered by scale-like setae; forewing hyaline without dark band; integument various, with pale spots................................... Cyrtagenia Evans  

5 Hind tibia serrate in profile, spines scale-like; propodeum somewhat flat in profile view and without abundant erect setae.......................................................................................... Priophanes Banks  

- Hind tibia not serrate in profile, if spines are present, then never scale-like; propodeum rounded in profile view and with abundant erect setae......................................................................... Ameragenia Banks
