Key to Tribes of South American Neopasiphaeinae

1. Forewing with two or three submarginal cells, if with three, then second usually much shorter than third on posterior margin (except in Reedapini ); inner metatibial spur of female ciliate to coarsely pectinate, not at all palmate and not thickened medially; scopa not hiding tibial surface; metabasitarsus of female flat or convex on outer surface, this surface superficially similar to that of metatibia, its setae longer than those of inner surface (ignoring setae of upper margin); apical process of eighth sternum of male usually with flat, bare apical region on upper side, superficially resembling a pygidial plate and usually exposed at apex of metasoma (a noteworthy exception is Eulonchopria Brèthes ) ....................... 2

—. Forewing with three submarginal cells, second usually about as long as third on posterior margin (except Lonchopria Vachal , s.str.); inner metatibial spur of female usually densely palmate-pectinate, bases of branches close together and diverging from thick part of rachis, or uncommonly coarsely pectinate (in Lonchorhyncha Michener ); metatibial scopa (except Lonchoprella Michener and Lonchorhyncha ) extremely dense, obscuring metatibial surface; metabasitarsus of female weakly concave on outer surface near upper margin, this surface unlike that of metatibia in appearance (except in Lonchoprella ), surface easily visible among setae that are usually shorter than those of inner surface; apical process of S8 of male lacking flat apical region resembling a pygidial plate .......... Lonchopriini

2(1). Forewing with two or three submarginal cells, if with three, then second much shorter than third on posterior margin; floccus-like setae absent on female metatrochanter ................................................................................... Eulonchopriini

—. Forewing with three submarginal cells, second about as long as third on posterior margin; floccus-like setae present on female metatrochanter ....... Reedapini
