Key to species of Podotarsonemus

1. Female and male: with seta on trochanter IV (e.g., Figs 2 View FIGURE 2 , 4 View FIGURE 4 ); female: coxisternal plates III–IV separate, longitudinal striae between coxisterna ( Fig. 2 View FIGURE 2 ); setae h small to moderate length, not attenuate (length <60); male: tarsus IV present, often rudimentary … australiensis species group................................................................... 2

- Female and male: without seta on trochanter IV; female: coxisternal plates III–IV not separate, lacking longitudinal striae between coxisterna ( Fig. 8 View FIGURE 8 ); setae h attenuate (length> 70); male: tarsus IV absent … boliviensis species group........... 4
