Identification
Elongate oval. Shining black with sinuate yellow vitta on each elytron, vittae broadly attaining margni at apex. Head, pronotum, and elytra closely punctate.

First 4 antennal segments of liebecki light brown, 5-11 dark brown; male with 5th antennal segment stouter than striolata but less stout than in P. zimmermanni.

Elytral pattern shared with P. robusta; in males, the shape and length of antennal segment 5 is different: only slightly shorter than 2-4, dilated apically, but not with internal process like in P. robusta.
