(modified from Gaimari & Mathis 2011 ) 1. Posterior ocelli in line with inner vertical setae; ocelli arranged in equilateral triangle or with distance between posterior pair greater than between posterior ocellus and anterior ocellus; frons flat to slightly concave. Scutellar disc bare. In profile, face usually distinctly angulate with frons at antennal insertion ( Odiniinae )...................... Odinia Robineau-Desvoidy - Posterior ocelli in front of line between inner vertical setae; ocelli usually arranged in isosceles triangle with distance between posterior pair conspicuously less than between posterior ocellus and anterior ocellus; frons usually relatively arched (sometimes conspicuously tuberculate). Scutellar disc sometimes setulose. In profile, face and frons more or less in line or sloping ( Traginopinae )............................................................................................ 2 2. Ocelli on moderately large to large tubercle, well in front of vertex.............................................. 3 - Ocelli and frons normal, lacking enlarged tubercle, but occasionally on raised bump little larger than diameter of anterior ocellus................................................................................................. 4 3. Arista long plumose. Vein M 1 strongly curved at apex....................................... Paratraginops Hendel - Arista pubescent. Vein M 1 straight ......................................................... Neotraginops Prado 4. Costa extended to vein M 1 . Genal seta present ............................................................... 5 - Costa extended to vein R 4+5 .

Postocellar setae present ................................................................................ 8 - Postocellar setae absent............................................................................... 10 8. Scutellar disc setulose. Several anterior fronto-orbital setae inclinate................................ Shewellia Hennig - Scutellar disc bare. Only one fronto-orbital seta inclinate..................................................... 9 9. Face uniformly yellow, lacking mid-longitudinal stripe. Lunule higher than frons. Antennae separated by a distance greater than 3X the diameter of a single antennal socket. Vein M 1 becoming distinctly weaker from crossvein dm-m towards wing margin.................................................................................... Helgreelia Gaimari - Face brown to black pruinose with white mid-longitudinal grey pruinose stripe. Lunule shorter than frons. Antennae separated by a maximum distance of 2X the diameter of a single antennal socket. Vein M 1 normal, distinctly reaching wing margin........................................................... Inpauema Limeira-de-Oliveira, Marques, Reis & Rafael 10. Four and/or five pairs of fronto-orbital setae. Dorsocentral setae 4 (1+3). Scutellum with setulae anterior to basal scutellar seta. Surstylus articulated with epandrium....................................................... Pradomyia Gaimari - Three pairs of fronto-orbital setae ( Figs 3–4 , 15–16 ). Dorsocentral setae 5 (1+4).
