Key to genera related to Odontomera

Odontomera and related genera differ from all other Richardiidae by the following combination of characters: Femora with apicoventral rows of spinose setae; postmetacoxal bridge complete; anal vein (A1) short, not reaching wing margin.

1. Head without orbital setae and lateral vertical seta; size large: body 15 mm, wing 11 mm ............................................................................................ Johnrichardia gen. nov.

­ Head with orbital and lateral vertical setae; size smaller: body less than 10 mm, wing less than 6 mm ............................................................................................................... 2

2. Crossveins r­m and dm­cu coincident or at least not as far part as length of crossvein dm­cu; scutellar setae 2 pairs ...................................................... Antineuromyia Hendel

­ Crossveins r­m and dm­cu farther apart than length of crossvein dm­cu; scutellar seta 1 pair.............................................................................................................................. 3

3. Frons, in lateral view, strongly developed dorsoanteriorly on ventral 1/2, with produced portion almost as long as eye is wide (fig. 4) ................... Oedematella Hendel

­ Frons not so produced, never more than 1/4 as long as eye width (figs. 3, 5)............. 4

4. Occiput, in lateral view, broad dorsally, as broad on dorsal 1/4 as on ventral 1/3 (fig. 5) .......................................................................................................... Sepsisoma Johnson

­ Occiput, in lateral view, narrow dorsally, much narrower on dorsal 1/4 than on ventral 1/3 (fig. 3)...................................................................................................................... 5

5. Postpronotal seta present; ocellar triangle base (posterior margin) well anterior to posterior eye margin ...................................................................... Macrostenomyia Hendel

­ Postpronotum without seta; ocellar triangle base more or less in line with posterior eye margin .......................................................................................... Odontomera Macquart
