Aedeagus and internal sac examined in three or two males, respectively.

DIAGNOSIS. Very similar and close to P. aethiops , being distinctive in having the body barely smaller in general; dorsum with a bit stronger greenish luster; sides of pronotum deeply sinuate in front of obtuse yet sharp basal angles, basal foveae narrow and deep, with inner basal sulcus very shallow to vague, lateral bead less wide in basal half and still less so at base, lateral groove mostly finely yet distinctly punctate in apical two thirds; elytral intervals convex.

Internal sac of aedeagus ( Figs 98–99 , 107–112 , 141 ) similar, except for proximal and distal vesicles small yet distinct and separate from dorsal sclerite.

REDESCRIPTION. BL 12.4–15 mm. Body dorsum black, pronotum often with very slight greenish luster or violaceous luster toward sides of base; elytra with faint greenish luster, interval 9 black or indistinctly violaceous. Pronotum cordate ( Figs 84–86 ). Propleura with a group of coarse and sparse to moderately dense punctures outside sternopleural suture.

GEOGRAPHIC DISTRIBUTION. Thailand; first reported from Vietnam.
