This species is like P. peninsularis and gigas, but a little 

 more elongate and with a less conspicuous hairy clothing. 

 The prothorax is exceedingly densely punctured and clothed 

 with closer but shorter hairs, its sides being nearly straight, 

 with a smooth shining margin, the posterior half of which 

 is rather broad. The elytra are well punctured but very 

 shining, and each has three slight costae which bear fine 

 hairs. The lateral edges of both prothorax and elytra are 

 furnished with long and close fringes. The legs are slender.
