1’ Epiproct lateral lobes, if present, not armed with tooth-like spines or serrae …….………………... 6

2 Lateral epiproct lobes diverging strongly from central axis, or curved strongly laterad near tip ( Figs. 4 View Figs , 7 View Figs ) ..…………...………………………...…. 3

2’ Lateral epiproct lobes variable, but not strongly divergent or apically curved ( Fig. 10 View Figs ) …………. 5

3 Epiproct apex consists of a pair of slender processes set between prominent lateral lobes ( Fig. 7 View Figs ) …………………………………… divergens

3’ Mesoapical section of epiproct consists of a wide, complex process set between lateral lobes ( Figs. 4 View Figs , 19 View Figs ) ………..………………………………………... 4

4 Mesoapical section of epiproct more-or-less cylindrical and projecting beyond lateral lobes ( Fig. 19 View Figs ) …………………………………….….. sapa

4’ Mesoapical section of epiproct somewhat forkshaped and not reaching apex of lateral lobes ( Fig. 4 View Figs ) …………………………………...……….…. caoae

6’ Epiproct apex notched ( Fig. 16 View Figs ) or truncate.…. 9

7 Mesal lobes of epiproct slender and much longer than broadly rounded lateral lobes ( Fig. 13 View Figs ) …. 8

7’ Mesal lobe of epiproct subequal in length and width to slender lateral lobes ( Fig. 24 View Figs ) ………. viet

8 Epiproct apex trifurcate; epiproct bearing several short, stout, ventral spines ( Figs. 13, 15 View Figs ) ………………………………………………. gressitti

8’ Epiproct apex with a long slender, apically notched lobe set between broad, rounded lateral lobes; epiproct without obvious ventral spines ( Figs. 1, 3 View Figs ) …………………………......….. bifurcata

9 Posterior margin of tergum 10 divided into a pair of upturned lobes; inner lobe of paraprocts with a small apical notch.………………….……. hainana
