Diagnosis: This species is somewhat similar to P. taiwanensis sp. nov., and they share the following character states: the short lateral teeth on pronotum of identical size and the row of long erect setae along each lateral margin of elytra. This species can be easily distinguished from P. taiwanensis sp. nov. by the weakly curved anterior margin of pronotum and the not impressed dorsolateral pronotum.

Distribution: Taiwan; Japan.

Remarks: Yoshida and Hirowatari (2013) described this species in detail with the male genital structure. This species was originally described from the Nansei Islands, southeastern Japan. Yoshida and Hirowatari (2013) suggested that this species originated from the southern part of continental China, based on its distribution. The data presented here show that P. hiranoi is distributed throughout Taiwan.
