Head and pronotum without microsculpture (FigsF2-63); pronotum with very dense punctation, midline glossy. ♂: male sternite VIII posteriorly convexly produced, neither concave nor excised (Fig. 64); aedeagus as in Figs 65-67. Sumatra, Bali....................................................................................................................... P. cameronicameroni (SCHEERPELTZ)   
- Head and pronotum with microsculpture; pronotum not with conspicuously dense punctation. ♂: male sternite VIII broadly concave to distinctly excised posteriorly; aedeagus of different morphology................................................................................................... B  
 2. Elytra short, approximately 0.9 times as long as pronotum (Fig. 32). Pronotum and elytra reddish, distinctly contrasting with the blackish-brown head. Pronotum with lateral margins subparallel, short, broadly rounded towards posterior margin (Fig. 32). ♂: sternite VIII posteriorly almost triangularly, broadly, and relatively deeply excised (Fig. 30); aedeagus as in Figs 33-34. Taiwan...................................................................... P. formosanusformosanus sp. n.   
- Elytra approximately as long as, or longer than pronotum. Coloration usually different. Pronotum usually with posteriorly converging and longer lateral margins. ♂: primary and secondary sexual characters different............................................................................ C  
3. ♂: posterior margin of sternite VIII shallowly concave (Figs 10-11, 45-46, 57)........... D  
- ♂: posterior margin of sternite VIII distinctly and more narrowly excised in the middle (Figs 25, 40)................................................................................................................ F
