Key to extant genera of Odiniidae View in CoL View at ENA in the Neotropical Region and to species of the Pauximyia gen. nov.

(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 View in CoL )...................... Odinia Robineau-Desvoidy View in CoL

- 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 View in CoL )............................................................................................ 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 View in CoL

- Arista pubescent. Vein M 1 straight ......................................................... Neotraginops Prado View in CoL

4. Costa extended to vein M 1. Genal seta present ............................................................... 5

- Costa extended to vein R 4+5. Genal seta absent.............................................................. 7

5. Scutellum at most bearing 2–5 setulae along margin.......................................... Lopesiodinia Prado View in CoL

- Scutellar disc and margins bearing numerous setulae......................................................... 6

6. Only anterior fronto-orbital seta inclinate.................................................. Schildomyia Malloch View in CoL

- Several anterior fronto-orbital setae inclinate............................................ Neoschildomyia Gaimari View in CoL

7. Postocellar setae present ................................................................................ 8

- Postocellar setae absent............................................................................... 10

8. Scutellar disc setulose. Several anterior fronto-orbital setae inclinate................................ Shewellia Hennig View in CoL

- 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 View in CoL

- 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 View in CoL 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 View in CoL

- Three pairs of fronto-orbital setae ( Figs 3–4 View FIGURES 1–7 , 15–16 View FIGURES 13–18 ). Dorsocentral setae 5 (1+4). Scutellum lacking setulae. Surstylus non-articulated with epandrium ( Figs 9, 12 View FIGURES 8–12 , 20 View FIGURES 19–23 )............................................... Pauximyia View in CoL gen. nov.... 11

11. Lunule with velvet black band through upper part of antennal bases ( Figs 3–4 View FIGURES 1–7 ). Hind tibia almost as long as fore tibia ( Fig. 1 View FIGURES 1–7 )............................................................................. Pauximyia oliveirai View in CoL , sp. nov.

- Lunule entirely white ( Figs 15–16 View FIGURES 13–18 ). Hind tibia about half the length of the fore tibia ( Fig. 13 View FIGURES 13–18 ).... Pauximyia vidali View in CoL , sp. nov.
