Key to the Species of Phellopsis 

1 Lateral margin of elytra appearing smooth in dorsal view ( Fig. 2View FIGURE 2 A –B); North America. ......................... 2

- Lateral margin of elytra appearing serrate in dorsal view ( Fig. 3View FIGURE 3, 4View FIGURE 4 A –D); Asia ........................................ 3

2 Hypomeron lacking intertuberculate setae ( Fig. 2View FIGURE 2 C); lateral margin of pronotum strongly bisinuate in lateral view; elytral punctures large, discal tubercles less than ¼ diameter of puncture; posterior margin of prointercoxal process straight to weakly concave. Eastern North America. ............... P. obcordata  (Kirby)

Western North America............................ P. porcata  (LeConte)

3 Outer margin of suprantennal ridge emarginate; head between frons with very large tubercles ( Fig. 6View FIGURE 6 B); gula at narrowest point approximately 0.2 X the width of the apex of the submentum ( Fig. 7View FIGURE 7 A). Japan...... ............................................................................................................................................ P. suberea  Lewis

Western China. .................. P. yulongensis  Foley and Ivie n.sp.
