Key to the species of Onomeris 

The pill millipede fauna of America is still relatively little known. Careful examination of the telopods of any Glomerida  specimen found in America is therefore necessary to identify the species. For example, an undescribed genus co-occurs with O. sinuata  and has similar colouration and size. Additional undescribed Glomerida  species probably occur in the eastern United States.

1. Posterior margin of anal shield in males medially strongly concave ( Fig. 5View FIGURE 5 E). Tibial process of telopod slender, not tapering towards tip; tibia without trichostele ( Fig. 5View FIGURE 5 B)............................................................... 2

- Posterior margin of anal shield in males medially only very weakly concave. Tibial process of telopod triangular, basally wide, apically tapering; tibia with trichostele ( Figs 7View FIGURE 7 C, D). Cumberland Plateau, NW Alabama to Virginia............. O. sinuata 

2. Syncoxital lobe of telopod subtrapeziform ( Fig. 3View FIGURE 3 B). Third antennomere 2 x as long as second, sixth antennomere 2.1 times longer than wide ( Fig. 1View FIGURE 1 A). Known from Alabama, Georgia and Mississippi............................ O. underwoodi 

- Syncoxital lobe of telopod bilobed ( Fig. 6View FIGURE 6 C). Third antennomere 1.5 x as long as second, sixth antennomere 2.5 times longer than wide. Known from Virginia, Georgia and North Carolina......................................... O. australora
